Welcome to the Poway Auto Repair automotive blog. Today, let’s talk about the effect of tire tread depth on braking. When talking about stopping power, most Poway and Poway motorists tend to focus on our brakes. But our tires are where the rubber meets the road. So having good brakes isn’t enough. Safe Poway drivers need to have tires with enough traction to translate braking power into stopping power.

Let’s focus on stopping in wet Poway conditions. In order for a tire to have good contact with the road, it has to move the water out of the way. If it can’t move the water, the tire will actually ride on top of a thin film of water.

That’s called hydroplaning. If it’s really bad, Poway motorists can actually spin out of control – endangering themselves and the other drivers around them. At best, you won’t stop as fast.

So how does a tire move water? It has channels for water to flow through. Look at your Vehicle tire and you’ll see channels: channels that run around the tire and channels that flow across the tire. They’re designed to direct water away from the tire so it can contact the road better.

And the deeper the channel, the more water it can move. A brand new Poway Auto Repair tire has very deep channels and can easily move a lot of water. As the tire wears down, the channels become shallower and can move less water. When it wears down enough, it can seriously affect your ability to stop your Vehicle on wet Poway roads.

So that’s why it’s so important for California motorists to replace their Vehicle tires when they get worn. Consumer Reports and other advocate groups call for a standard of 3/32 of an inch and they have the studies to prove it.

By comparison, you’ve probably seen the wear indicator that’s molded into tires. When tires are worn 3/32 of an inch, the tread wear bar is visible. So the recommended standard has twice the tread depth as a completely bald Vehicle tire.

At Poway Auto Repair , we want our customers to know that the deeper recommended tread depth makes a big difference. Stopping distances are cut dramatically on wet Poway expressway. A safe stop from California expressway speeds with 4/32 of an inch of tread would result in a crash with worn out tires.

There’s an easy way to tell when a tire’s worn to 4/32 of an inch. Just insert a quarter into the tread. Put it in upside down. If the tread doesn’t cover George Washington’s hairline, it’s time to replace your Vehicle tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.

Many Poway motorists have heard of this technique using a penny and Abe Lincoln’s head – the old method. That measure gives you 2/32 of an inch – half the suggested amount. Of course, Vehicle tires are a major purchase. Most of us in Poway want to get as many miles out of them as we can. But there’s a real safety trade-off. It’s your choice.

Your engine is like a finely choreographed dance. All the parts have to work together. If the timing is off at the ballet, dancers crash into each other and fall down. It the timing is off in your engine, it may not run at all. One of the most intricate dances in your engine, has to do with the combustion cycle.

Your Vehicle engine has cylinders in which a piston travels up and down. At the top of the cylinders are valves open to bring in the air and fuel. And there are valves that open to let out the exhaust after the fuel has been burned.

Call Poway Auto Repair at (858) 748-0561 for answers about your timing belt, or drop by our Poway California service center on 13907 Poway Rd Suite A, 92064

It’s critical that the values be timed to open and close at precisely the right time in the combustion cycle, or the engine will run poorly or not at all.

The timing belt is responsible for rotating the shafts that control the valves. It’s vital and precision work. Timing belts are made of very tough flexible material. They can last a long time. But they eventually wear out and can break. The consequences can be disastrous.

In some engines, the valves actually protrude far enough into the cylinders that they could come in contact with the piston. If the timing belt breaks, the pistons will smash into the valves. Valves get bend or broken. If the engine is spinning fast enough, the broken parts will shred the cylinder head as well. Repairing this damage can cost several thousand dollars.

It’s a sad day when this happens; especially since it usually can be avoided. Manufacturers have issued recommendations for when you should replace your timing belt. For some engines, it’s at 60,000 miles. For others it’s at 90,000 miles or more. If you’re approaching 60,000 miles, or have passed it, make sure you check your owner’s manual or with your Poway California auto service advisor at Poway Auto Repair for when the timing belt should be replaced. Don’t let this one slip by.

Now some timing belts are visible and can be inspected. Others are hidden under a protective cover and are hard to get to. Some timing belts also drive the water pump. If you have a leaky water pump, the coolant will contaminate the timing belt and could make it fail sooner. So if you have this kind of engine, get it in to Poway Auto Repair for an inspection right away if you have a coolant leak.

Most people in the Poway area with this engine design end up with a new timing belt when they replace the water pump. And when you’re having your timing belt replaced on schedule, check with your Poway California auto service advisor at Poway Auto Repair to see if it makes sense to install a new water pump, even if it isn’t currently having problems, since most of the labor is already being done any way for the timing belt replacement.

As a heads up; larger engines will often have metal timing chains rather than belts. The chains don’t need to be replaced like belts.

We’ve already told you how very expensive it can be to get your car running again after a timing belt fails. You also need to know that replacing the timing belt is very labor intensive and is one of the most costly maintenance services you will have. So if you will be at the point where your timing belt should be replaced in the next year or so, ask for an estimate from Poway Auto Repair in Poway California so you can begin to prepare for the expense.

Under-inflated tires waste gas for lots of folks in the Poway area. Think how hard it is to walk in sand – you just have to work harder because of the resistance. When your tires don’t have enough air in them, their rolling resistance is dramatically increased and it simply takes more gas to get from Poway to Poway .

Always check your tire pressure when you gas up at one of our local Poway service stations. If they’re low – even just a little bit – bring them up to proper pressure. There’s a sticker on the inside of your driver’s door that gives the manufacturer’s recommended tire pressure.

And don’t rely on your tire pressure monitoring system to alert you to when you need more air. The TPMS system is set to warn you when pressure drops twenty percent below recommendations. That’s severely under inflated and you needed more air a long time ago. And if you have a slow leak – get it fixed right away at Poway Auto Repair .

Get some air and save some gas.

Our cars have to operate in a wide range of Poway, California temperatures and our engine coolant must be able to perform ‘no matter what’. Think for a moment about the environment where the coolant works. Very hot, high pressure, corrosive…

And all the while, it has to protect the components of the cooling system from corrosion. These components are made from steel and aluminum, plastics and rubber. The coolant has to be formulated to protect against corrosion for all of these different materials. That’s why different manufacturers recommend different types of anti-freeze for our Poway, California vehicles.

There are several different ‘families’ of anti-freeze available to us here in Poway, California. Your owners’ manual will tell you what kind you should use. Of course, Poway Auto Repair will know what to put in your car.

It’s important to stay on top of this because coolant system failure is the most common mechanical problem people have here in Poway, California. Regular service at Poway Auto Repair needs to be done to avoid failures and also to keep your warranty in place.

While the specifics of the service required may vary from vehicle to vehicle, your service consultant at Poway Auto Repair will know what to do. You’ll be advised to replace the coolant at specified intervals.

Some manufacturers may recommend periodic coolant system flushes. A flush adds a cleaning step to the fluid replacement process. Again, check to see what your service consultant recommends.

Someday, you may have to deal with an overheating problem, so you need to know what to do if your coolant temperature warning light comes on or your temperature gauge is in the hot zone.

Now, overheating can be very expensive. You can literally melt down your engine and have to replace the whole thing. So take the warning signs seriously and take immediate steps.

First turn off the air conditioner. This will lower engine temperature right away. Next turn your heater to maximum heat and run the fan at high speed. You might need to roll down the windows, but this will take a lot of heat off the engine.

Pull over as soon as you can safely do so, especially if you are stuck in slow-moving traffic, and shut the car off. It may take as much as 45 minutes for the engine to cool to the point that it’s safe to operate the car again.

If you need to add water or antifreeze, be sure to wait until the car cools down. Opening the radiator cap or even the overflow bottle when the coolant is hot and under pressure may result in serious burns.

So after the engine has cooled for 45 minutes or so, look to see if the coolant is low in the overflow tank. If so, you can cover the overflow tank cap with a large cloth and open the lid. Then start the engine and pour in some water or antifreeze. Pouring it in when the car is running will circulate the new, cool fluid with the warmer fluid in the engine and avoid engine damage.

Of course, overheating is a serious problem and you need to get it fixed right away. Poway Auto Repair can make sure the coolant is right before you drive home.

Those spring and winter inspections really come in handy when they head off a cooling system problem. And don’t forget that severe service driving conditions, like towing or hot, dusty driving around Poway, California, mean that you’ll need to service your coolant more frequently.

At AutoNetTV, we suggest that you have Poway Auto Repair inspect your coolant system to find small problems before they become big, and to change belts and hoses before they fail. After all, we don’t want you to lose your cool out there in Poway, California.

Working up a sweat is a great thing to do in a gym around Poway, but not in your car. When your car’s AC System has a problem, you’ll often feel it right away. The question is, how long do you put up with it? You know, the old comfort versus cost dilemma. But a more comfortable drive around Poway has a lot of benefits, and keeping the AC System well maintained can help prevent expensive repairs.

A common cause for AC failure is water and air in the system. The system does not work as well with air in it. And water can cause rust that leads to damage of the A/C components. Also refrigerant, the stuff that makes the air cold, can leak out, reducing the efficiency of the system, making it work harder to try to cool the air. That is why periodically evacuating the air conditioning system and recharging it keeps the proper amount of clean refrigerant in the system so it cools better and lasts longer.

You should also run the air conditioner regularly, even in the winter, so that it lubricates itself and keeps the seals from drying out. The seals can crack and that leads to leaks. Your owner’s manual will have recommendations for how often to service your air conditioner. Some service centers also have this information as part of their computer databases. Your service advisor at Poway Auto Repair can give you more information.

Of course, if your AC currently isn’t working right, then now is the time to get it checked. Many service centers such as Poway Auto Repair can inspect and test your air conditioning and offer evacuation and recharge services. This goes a long way to avoiding having to bring your air conditioner in for major repairs.

Recent environmental laws have stopped the manufacture of Freon, a refrigerant that was common in cars made before 1993. There is a very limited supply of Freon so the price is very steep. It may not be worth its weight in gold, but it probably is worth its weight in silver. If you have an older vehicle that uses Freon, you may want to consider having it retrofitted to use the new EPA-approved R134a refrigerant. It will pay for itself in the long run.

There was a man in Poway who learned that most car accidents occur within a mile of home – so he moved. (Just Kidding!)

When we think of defensive driving, we often focus on our local California highway situations. The fact of the matter is we need to be just as careful close to home in Poway, because that’s where we do most of our driving. We can’t let our familiar surroundings keep us from driving defensively.

Defensive driving begins with the proper attitude. Have in mind that you won’t let anyone take your safety away from you. You’ll be aware of your surroundings, road conditions, other vehicles and hazards. And the first person to be concerned with is you: start with your own environment.

Don’t leave without securing all occupants including children and pets. Watch for loose items that can become projectiles during evasive maneuvers.

Driving too fast or too slow increases the chance of an accident.

Never drive impaired: Alcohol is a factor in half of all fatal crashes. Never drink and drive.

Other impairments include being sleepy, angry, daydreaming or talking. If you suddenly wonder how you got where you are – you’re not paying enough attention.

Keep your windows clean and uncluttered. No fuzzy dice and stickers.

Keep your car in good shape so that it handles properly: Maintain tires, lights, brakes, suspension, wheel alignment and steering.

Always use your turn signals while driving around Poway California. Avoid other vehicles’ blind spots.

Don’t drive faster than your headlights – if you can’t stop within the distance you can see, you’re going too fast.

Avoid driving over debris in the road. Even harmless looking items can cause damage or an accident.

Keep your wheels straight when waiting to turn at an Poway California intersection. That way if you’re hit from behind, your car won’t be pushed into on-coming traffic.

My daddy always said that when you drive, you’re actually driving five cars: yours, the one in front, the one behind and the ones on either side. You can’t trust that other drivers will do the right thing, so you’ve got to be aware of what they’re doing at all times.

If you see another car driving erratically, weaving, crossing lanes, etc., stay back. Take the next right turn if you’re downtown Poway, or take the next exit on the California highway. Notify the police if you see someone driving dangerously in our Poway community.

Never follow too close. The minimum distance is the two second rule. Pick a landmark ahead, like a tree or road marker. When the car in front of you passes it, start counting: ‘one-one-thousand, two-one-thousand’. If you pass the landmark before reaching two-one-thousand, you’re following too close.

Remember that the two second rule is the minimum – it assumes you’re alert and aware. Three seconds is safer. Move out to five seconds or more if it’s foggy or rainy.

Someone will inevitably move into your forward safety zone – just drop back and keep a safe distance.

If someone follows you too closely, just move over.

Don’t play chicken by contesting your right of way or race to beat someone to a merge. Whoever loses that contest has the potential to lose big and you don’t want any part of that. So stay alert, constantly scan around your car and arrive safely.

You would never like to drink a glass of mud, right? Well, your car feels the same way. It needs a steady supply of clean fuel in order to run well and deliver good fuel economy. The fuel filter’s job is to clean dirt and rust out of the fuel before it gets to your engine. A clogged fuel filter can actually choke off the engine so that it won’t start or run. Some fuel filters have a bypass valve that allows fuel to go around the clogged filter so your car will still run. But, then the contaminated fuel can plug your fuel injectors and allow damaging particles into your engine.

A car with a partially clogged fuel filter might run well around town, but sputter and strain on the highway because it’s starving for gas. There are two things that affect how often you need to replace the filter. They are: where you drive and the gas you buy. If you drive a lot on dirt or gravel roads in rural California, your fuel filter will have a harder time keeping the fuel clean.

And, we hate to say it, but buying the cheapest gas from cut-rate Poway area stations sometimes means dirtier fuel that’ll clog the filter sooner. Major brands tend to be cleaner and certainly have higher levels of detergent additives.

Of course, your manufacturer recommends intervals for changing the fuel filter. But, it’s a little more complicated than that. Some manufacturers stopped listing recommended intervals for fuel filter replacement or have very long intervals like every five years or eighty thousand miles. So you may need to look to other sources for recommendations. Cars older than six or seven years are especially at risk because they have had time for dirt and rust to build up in the fuel tank. A clean fuel filter keeps the gas flowing. Even a partially clogged filter puts added strain on the fuel pump. That can shorten its life and result in a costly repair.

As is often the case, spending a little money now on something as inexpensive as a fuel filter can save money down the road. At Poway Auto Repair in Poway, we can check your fuel filter. It is better than fixing a burned out fuel pump or ruined fuel injectors.

Today we’re going to be talking about serpentine belts for our Poway California customers. Let’s start by talking about the accessories that are driven by the serpentine belt. First is the alternator. That’s the device that makes electricity to power the vehicle and recharge the battery. Then there’s the air conditioning compressor that makes cool air for you while you’re driving around Poway California in the summer.

The power steering and power brake pumps are driven by the serpentine belt in most vehicles. Those pumps make the pressure that assists your steering and braking.

In many vehicles, the water pump is driven by the serpentine belt. The water pump is what circulates the coolant that protects your engine. In some cars around Poway California, the water pump is driven by the timing belt.

The radiator cooling fans on some vehicles are also driven by the serpentine belt. Some have separate electric motors. That’s really a lot of work for one belt.

But modern engine design has a single belt that snakes around the front of the engine and drives most if not all of these accessories. Serpentine belts do a lot of work, but they’re tough and can last for thousands of miles.

Just how long will they last? That’ll vary for each individual car in the Poway California area. Your manufacturer will have a recommendation for when it should be changed, but it could need it sooner. The good news is that a visual inspection can reveal a belt that’s getting close to failing.

Poway Auto Repair can look at the belt: if it has more than three or four cracks per inch it needs to be replaced. A deep crack that’s more than half the depth of the belt – replace. Frayed, missing pieces, a shiny glazed look? It’s out of there.

What’s involved in replacing the belt? First the old belt is removed. Then a new one is fitted around all the pulleys for the accessories and the drive. There’s a special pulley called a tensioner.

This pulley is mounted to the engine block with a spring loaded arm. Its job is to apply the correct amount of tension to the belt to keep it from getting loose and maybe slipping off. Because the spring in the tensioner pulley wears out, AutoNetTV recommends replacing them at the same time as the belt. It just makes sense.

What are the warning signs that there’s a problem with the serpentine belt? You may hear a squealing sound from under the hood when accelerating around our Poway California streets. A loose belt might give you a slow, slapping sound.

What do you do if your belt breaks? If you’ve actually had that happen on our local Poway California freeway, it can be a little scary. Often the first thing you notice is that you have no power steering or power brakes. Don’t panic – you can still steer and brake, but you’ll have to do the work. It’ll be harder to steer and you’ll need more time and effort to stop, so plan accordingly.

Your dashboard will light up will all kinds of warnings. You’ll see a warning about your cooling system if you have a water pump that’s driven by the serpentine belt. This is very critical because without your cooling system working, your engine will overheat. If you don’t stop you’ll have massive engine damage, maybe to the point that you need a new engine. Pull over as quickly as you safely can. Open your windows and turn the heater on full blast to provide a little engine cooling and pulled over as soon as possible.

The battery light will come on because the alternator isn’t working. If your car’s water pump isn’t driven by the serpentine belt, you’re not in danger of overheating so you can drive a little further if necessary. But the battery will run down to the point where the car won’t run and will just shut off. You don’t want that to happen while you’re driving in our local Poway California traffic.

Remember, this does not have to happen if you replace your serpentine belt on schedule. Ask your technician at Poway Auto Repair to check your belts and hoses from time to time so you can take care of them if they need to be replaced prematurely.

This is something really amazing: For every gallon of gas your Poway car burns, it uses 12,000 gallons of air. All of that air has to be filtered to keep your engine clean.

That’s like a hundred gallons of air every block! The engine air filter is just another example of a very inexpensive part that has to do a tremendous amount of work. And when it works, everything goes well. But, when it doesn’t, well, it can lead to costly problems. Of course, your manufacturer recommends intervals for changing your air filter. But like most service intervals, where and how you drive your car affects when your filter needs to be changed.

Dusty conditions in and around Poway or polluted city driving means you’ll need to change your filter more often. Your Poway Auto Repair technician can check your filter for you. In fact, it’s often a routine part of an oil change.

When you think about it, a clogged air filter won’t allow as much air through as a clean filter. Your car needs this air to efficiently burn its fuel, giving you better fuel economy and performance.

Dirtier filters don’t work as well as clean ones. A filter can only hold so much, after that, it allows dirt to pass right into your engine. Air filters come in all shapes and sizes. They also come in different grades. There are high performance air filters available for most cars. These high performance filters cost a little more, but they increase horsepower and may improve fuel economy to boot.

So have your air filter checked. If it needs replacing, it doesn’t cost very much and it should easily pay for itself in better fuel economy before your next oil change.

Stop by Poway Auto Repair at 13907 Poway Rd Suite A, Poway, California 92064, and we’ll take a look at your air filter for you. Feel free to give us a call at (858) 748-0561 to make an appointment.

Ever heard the sad tale of a staggering repair bill from a broken timing belt? Bad news. Let’s take a lesson from their woes and remember to think about our timing belt.

First, let’s review what a timing belt does. The top part of the engine, over the cylinders is called the cylinder head. The head contains the valves. There’s at least one valve that lets the fresh air into the cylinder. This air, mixed with fuel, burns to create power. Then another valve or two open to allow the exhaust out of the engine. Each cylinder has 2 to 4 valves – that’s 12 to 24 valves for a V-6, up to 32 values on a V-8. The opening and closing of the valves is done by a camshaft. The timing belt uses the rotation of the engine to drive the camshaft which opens and close the valves. It’s called a timing belt because it has to be adjusted to rotate the camshaft to keep proper time with the engine so that everything’s in sync.

The timing belt is a toothed rubber belt . But some cars use a timing chain or timing gears instead of a belt. Timing chains and gears are much more durable, but manufacturers are using belts more because they are quieter – and cheaper. If you have a small or mid-sized passenger car, crossover or mini-van, chances are you have a timing belt.

Unfortunately, timing belts fail without any warning. That shuts you down right away. A technician can inspect your timing belt and look for cracks and looseness. But getting to the belt to take a look can be almost as much work as changing it on some cars. That’s why manufacturers recommend replacing the belt from time to time. For most vehicles it’s from 60,000 to 90,000 miles or 95,000 to a 145,000 kilometers. If your owners’ manual doesn’t specify an interval ask your service advisor.

One AutoNetTV producer has had two timing belts fail. The first was while he was waiting at a stop light – that repair cost several thousand dollars. The second was while driving on the highway – that one cost more than twice as much. Both had the cars out in the shop for three weeks. His cars had what we call “interference engines”, meaning that the valves and pistons are very close to each other. If the timing belt slips even one notch, the pistons will slam into the open valves. That’s why our friend’s highway failure was so much more expensive – his engine was traveling so fast that the valves were smashed and they chewed up the cylinder head.

A non-interference engine will just shut down if the timing belt breaks. You’re stranded, but the engine doesn’t suffer permanent damage. In both cases, our hapless friend was just a couple oil changes past the recommended interval for changing the timing belt. This is one of those things that you just cannot put off. Now replacing a timing belt is not cheap – but repairs for a broken belt can be many times as much.

Check your owners’ manual right away – especially if you have more than a 60,000 miles or 95,000 kilometers. You may need to get that belt replaced right away. And on many cars, the timing belt drives the water pump. So, it may be a good idea to replace the water pump while you’re at it because 90% of the work required for the new pump is already done with the belt change. Doing both at the same time saves you a lot of money because as they say, “timing’s everything”. Parts, Timing Belt
