Every Glendora car owner who has taken their car in for an oil change has been told that their engine air filter’s dirty.

Here’s what goes into the determination of when to change the filter: First, your sedan owner’s manual will have a recommendation of when to change the filter. Second, a visual inspection by your Los Angeles technician may determine that your filter it is visibly dirty and needs to be changed.

So between your owner’s manual and your Los Angeles technician’s inspection there’s really no guesswork involved.

Now, most air filters purchased in Azusa, Covina, or San Dimas don’t cost a lot to replace. It’s just that California people hate getting caught with an unexpected expense. On the plus side, though, changing a dirty air filter at Certified Auto Specialists can often save enough on gas to pay for itself before your next oil change in Los Angeles.

Think about a dirty furnace filter in your Covina home. When it’s all clogged up, enough clean air can’t get through. In your sedan, that means that your engine can’t get as much air as it needs to burn the fuel efficiently. So it makes do with less air and has to use more expensive California gas to move your vehicle around Los Angeles roads.

Your sedan actually needs about 12,000 gallons of air for every gallon of gas it burns. Engine air filters don’t cost much in Glendora at Certified Auto Specialists. When it’s time to change yours, just get it done. You’ll buy less fuel, have better performance and protect your engine.

Today we’re going to be talking about serpentine belts for our Glendora, 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 sedan and recharge the battery. Then there’s the air conditioning compressor that makes cool air for you while you’re driving around California in the summer.

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

In many sedans, 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 Glendora, California, the water pump is driven by the timing belt.

The radiator cooling fans on some sedans 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 Glendora, California area. Your auto 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 at Certified Auto Specialists can detect a belt that’s getting close to failing.

Your reliable Certified Auto Specialists tech 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? Toss it.

What’s involved in replacing the belt at Certified Auto Specialists? 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 and the automotive professionals at Certified Auto Specialists recommend 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 Glendora 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 a busy Los Angeles highway, it can be a little scary. The first thing Glendora car owners usually notice is that they 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. Open your windows and turn the heater on full blast to provide a little engine cooling. Pull over as quickly as you safely can!

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 will just shut off. You don’t want that to happen while you’re driving in our local Glendora, California traffic.

Remember, you can avoid this stressful scenario if you replace your sedan serpentine belt on schedule. Ask your reliable Certified Auto Specialists service specialist to check your belts and hoses from time to time so you can take care of them if they need to be replaced prematurely.

The hottest Glendora news story may be different everyday, but there’s one topic that seems to come up over and over again – the price of gas in Glendora. But we’ve found several basic things that any Glendora vehicle owner can do to greatly reduce their gas consumption, save money, and help the Los Angeles environment. You can really impact your fuel economy by how you drive – but first, here’s a review of things you can do for your car that’ll save gas no matter how you drive.

The first one is keeping your tires properly inflated. That can save two miles per gallon. Driving on low tires is like driving through sand – your car just has to work harder. Most Glendora service centers will fill up your tires for free, so just ask your service advisor. Also, make a habit of checking your tire pressure whenever you get gas in your car. Many Glendora gas stations have an air hose you can use for free.

Another important item is to keep your air filter clean. An air filter all clogged up with dirt and bugs doesn’t let enough clean air through to efficiently burn fuel. Using a dirty air filter will cost you almost two miles per gallon in reduced fuel efficiency. And worn spark plugs can cost another two. A spark plug can fire as many as 3,000,000 times for every thousand miles driven. Check the owner’s manual for replacement recommendations.

The biggest item is the oxygen sensor. This device provides the engine management computer with information it needs to fine-tune the fuel/air mix. When that’s messed up it can cost up to three miles per gallon. And of course, there’s dirty or substandard oil. Dirty oil causes extra drag. The wrong grade may be too thick. That’s another .4 miles per gallon right there.

One item Glendora residents seldom think about is their gas cap. A worn, loose or missing gas cap can cost another two miles per gallon. Adding up all of these worn, missing or sub-par items leads to a total of almost 11.4 miles per gallon in reduced fuel efficiency! And with current gas prices in the Glendora area, the cost really adds up. Taking care of these simple maintenance items will save big bucks at the pump.

Now most people aren’t missing on all of these items, but think about which ones might affect you right now! And don’t forget tune-ups, dragging brakes, low transmission fluid, fuel system cleaning, wheels out of alignment, PCV valve, fuel filter and other key services spelled out in your owners’ manual.

Certified Auto Specialists knows all this stuff and can tell you when you’re scheduled to take care of each item. Create a system of your own to track your service schedules, or just use the computer system at Certified Auto Specialists – which may also be updated with recall notices and maintenance schedule items from your manufacturer.

If you aren’t currently using synthetic motor oil in your Glendora vehicle, maybe now’s the time to consider it. Need more information? Well, synthetic motor oil is a substitute for petroleum based oil.

Synthetic oil doesn’t gel or gum-up like petroleum based oil and it doesn’t vaporize as easily. It protects better in severe driving conditions like stop and go driving around Glendora, as well as in very hot or very cold conditions. More and more new vehicles are being delivered with full synthetic motor oil; with the recommendation to use synthetic for the life of the vehicle.

Why is this? Synthetic motor oil maximizes engine power and fuel economy. To see why; we’d need a microscope, so we’ll have to settle for using our imaginations.

The molecules of conventional motor oil are long hydrocarbon chains. Synthetic motor oil, on the other hand, has uniform, round molecules. Which is more slippery, a pile of pencils or a pile of marbles?

Synthetic motor oil lubricates better because there’s less friction. That means better wear protection, cooler operating temperatures, more power and better fuel economy. And synthetic oil doesn’t sludge up like conventional oil, so it prevents those small oil passages from clogging up.

Some manufacturers are extending oil change intervals. The added protection of synthetic oil covers you for these longer intervals. Talk with your service advisor about how you drive and see if he thinks you can benefit from synthetic oil. Also ask about the appropriate oil change interval for synthetic, because it may very well be longer than for conventional oil.

Most of us here in Glendora have a busy life and might occasionally miss an oil change; go ahead admit it. Since we’re not perfect, doesn’t it make sense to use a motor oil that’s got your back?

Now synthetic oil costs more. But it lasts longer, protects better and increases fuel economy. You’ll likely save money in the long run. If you’re serious about making your car last longer, start using synthetic motor oil right away.

If you’re reading this article in Glendora, California, then you probably care about your car and how it runs. Even though you care, there is still that moment of dread when your service technician tells you the manufacturer recommends some additional service. Your heart beats a little faster, your blood pressure rises. You worry about spending more money than you had planned. And you worry that if you say “no”, you might be harming your sedan or risking your family’s safety.

At the risk of sounding like your dad, you really should have done your homework. Service recommendations are in your owner’s manual. But it is not like you want to keep your sedan auto maintenance schedule on your nightstand for bedtime reading.

Cars are complicated machines and it takes some effort for Glendora auto owners to keep them running well. That is why auto makers have maintenance schedules that explain how to keep your sedan performing efficiently and prevent costly breakdowns. In a typical owners manual you’ll find: oil change, brake fluid and pad change, coolant system service, transmission service, battery electrolyte levels, cables and terminals, tire pressure and wear, CV boots, cabin air filter, air conditioning, heater, fuel filter, air filter, belts and hoses, power steering fluid, differential service, fuel system cleaning, and wheel alignment. And then there are mechanical service requirements like timing belt changes, valve adjustment, steering function, engine and exhaust leaks – yeah, it is a really long list!

Fortunately, this isn’t a test: Covina auto owners don’t need to have it memorized. Your reliable Certified Auto Specialists service advisor has access to your manufacturer’s recommendations. Don’t be surprised when your service advisor at Certified Auto Specialists reminds you something is due. Your manufacturer has taken great care in putting together your maintenance schedule. Let Certified Auto Specialists help you stay on top of important maintenance. You can expect them to suggest recommended services and tell you what problems they find under the hood. We’ll also explain how urgent these services are so you can work them into your budget.

In our auto video today we’ll be talking with Alan Peterson about myths surrounding automotive maintenance. You can lump these myths into the statement that “modern cars are so reliable, they are virtually maintenance free”.

Any good myth has some elements of truth. No offense to Glendora Bigfoot fans, but this maintenance-free myth has more evidence than most. If we look at some isolated areas of auto maintenance, we could conclude that maintenance isn’t so important. But other areas would just as easily lead you to believe that maintenance is more important than ever.

Here are some examples for our friends in Glendora.

• Some cars in Glendora no longer require chassis lubrication. They’re made with self-lubricating materials and have sealed joints. There’s literally is no way to grease those joints.

-Chalk one up for the myth.

On the other side, some vehicles come with sophisticated variable valve timing. A lot of complicated parts up in the valve train that didn’t even exist not that many years ago. These parts are very vulnerable to oil sludge.

• So, skipping an oil change here and there could lead to very expensive damage.

-A point to maintenance.

• Electronic ignition has eliminated replacing points.

-Myth gets a point.

• Fuel injectors on direct injection engines are very expensive to replace so one must be sure to get a fuel system cleaning on schedule.

-Point for maintenance.

I think you get the picture. As automotive technology advances, it eliminates or reduces some maintenance requirements. And maintenance becomes more critical for some items. Most others remain very similar to what they’ve always been.

So the maintenance mindset is still important for car owners in Glendora if we want our vehicles to last a long time. The checklist may change over time, but there’ll always be a check list.

Let me mention a couple of items on modern vehicles that folks need to be aware of. One of the most of the most important is timing belt replacement. Used to be that all engines had timing chains – you know, metal chains. They rarely broke.

It’s cheaper to make engines with timing belts rather than chains, so replacing the timing belt is on most engines’ maintenance list. The money the manufacturer saves by using a belt is more than off-set by what the vehicle owner has to pay to replace the belt. And it’s a drop in the bucket compared to the cost of repairing the damage if the timing belt breaks.

So make sure you know when your timing belt needs to be replaced. You don’t want to miss that. If you have 60,000 miles or more, break out your owner’s manual or ask your Glendora service advisor at Certified Auto Specialists to check on the recommendation right away.

Another is sealed wheel bearing assemblies on some vehicles. As you might have guessed, it’s cheaper to make a sealed unit than one that has access to inspect or service the wheel bearings. The problem is that when the bearings fail, you have to replace the entire unit, not just the bearings. That’ll cost 5 or 6 times as much.

For our friends in Glendora, we hope this has underscored the importance of knowing and following your maintenance schedule. Come in and see us at Certified Auto Specialists. You’ll find us at 476 Vermont Avenue in Glendora, California 91741. Just give us a call at 626-963-0814.

Sometimes we hear people say, “What’s up with all this maintenance stuff? Modern cars just don’t break down.” While it is true that today’s cars and trucks are extremely reliable, they are also becoming increasingly complicated and use more exotic materials than ever before. All that complexity demands higher tolerances for everything. For example, most folks don’t realize how high tech automotive fluids have become. Fluids like, engine oil, transmission fluid, coolant and brake fluid.

Did you know that a modern engine would not run for more than a few months using motor oil formulas from 30 years ago? Today’s automotive fluids contain a much higher percentage of additives to protect your vehicle’s components from premature wear and corrosion. Time and miles march on for all of our cars. Please don’t think we’re using scare tactics to get you to take care of your maintenance – but here are some personal stories from AutoNetTV staff members to emphasize the importance of getting things done when they are due. Names are withheld to avoid embarrassment to those who should know better. Even though they should know better, it usually comes down to real life: time and budget. But they are tales of a stitch in time saves nine.

The first comes from a staffer who bought a used pick-up truck for his son. The oil was clean and all the fluids were topped off. A short time later, the truck overheated on the highway and shut down. The repair shop diagnosed the problem: the radiator pan was corroded and dumped the coolant. Even though the coolant level was correct, it was clear that the coolant had never been exchanged – just topped off from time to time. While this kept the engine cool, all of the anti-corrosion additives had worn out; the coolant became acidic and ate through the radiator pan. The cost: hundred of dollars and four days in the shop. This demonstrates the need to get your coolant exchanged on schedule.

Another story involves the true cost of skipping an annual inspection. Our staffer took his SUV in for the California safety inspection to renew his registration. At the inspection station, he learned that the law had changed and that his newer rig only required an inspection every two years. He was very happy to save the $45 bucks. The problem was, his rear brake pads were very worn. Two months later, it was bad enough that he could hear the grind – over the radio, DVD player and the kids. He took it in to get the bad news. Both of the rear brake rotors were damaged. The left one could be resurfaced. The right had to be replaced. So saving a few bucks on his safety inspection turned into an extra $500 over what brake pad replacement would have been. Moral of the story: don’t skip your annual inspections. The irony is that many Glendora service centers would have done a brake inspection for free.

Next: a teenage daughter and a curb. Daddy’s little princess smacked a curb when she turned into a shopping center and popped the tire. The problem came when Dad didn’t get an alignment. The impact was hard enough to ruin the tire – so it was hard enough wreck the alignment. But instead of an alignment after the first tire, Papa ended up buying a second tire a few months later – and then an alignment.

Situation: son and wife with cars from the same manufacturer with essentially the same engine. Our staffer checked the son’s maintenance schedule and saw that it needed a timing belt replacement at 90,000 miles/145,000 km. He had it done – it cost several hundred dollars. His wife’s car had about 60,000 miles/97,000 km, so it should be ok for a while. Right? Wrong. The problem was that the wife had the turbo charged version. Its belt was scheduled for replacement at 60,000 mi/97,000 km. At 63,000 mi./101,000 km, the belt snapped on the interstate. The valves all crashed down into the cylinders at high speed and the entire head was shredded and had to be replaced. The cost: several thousand dollars. Does he wish he had checked the maintenance schedule? You bet he does – every time he passes a big-screen TV.

We’re talking about taking care of little things before they become big things. And when you take care of the little things, your car runs better and is more economical to operate. Remember to save those maintenance records. It’ll show potential buyers that you’ve taken care of your vehicle and it will help you get a better price. Or when you buy a used car, check those records. If there aren’t any, assume that the maintenance hasn’t been done and take it to your Covina or San Dimas service center for an inspection. Take care of unperformed maintenance sooner rather than later.

We live in such a disposable society. It’s amazing all the stuff we throw away. New stuff comes out so fast, we just toss the old and move on. In the old days people were real sticklers about taking care of their things. If something got lost or ruined by neglect, tough – they had to do without. Most people couldn’t afford new cars very often, so they had to make them last as long as they could.

It’s a good thing that cars are more reliable these days. They just don’t break down as often. And the good news for us California penny pinchers is that a modern car can easily go 200,000 miles/320,000 km with proper care. The engineering and the manufacturing quality is tremendous. The missing ingredient is us Glendora car owners making sure we follow the manufacturer’s recommended maintenance schedules.

Every time you go a couple thousand extra miles between an oil change, you have created an opportunity for sludge to be formed and clog passages. Then some parts don’t get properly lubricated and they start to wear out faster. Skip a cooling system service, and the corrosion inhibitors become depleted, and the radiator starts being damaged – one step closer to a failure. Same thing is true for transmission service, power brakes, fuel system cleaning – really everything on your schedule.

It is probably even more important for older vehicles. Those engines and other systems have had more time to get dirty, so they are a bit more stressed anyway. But it is never too late to get back on track with your maintenance and to hold off further damage.

And it really does start with the oil change. When you get a full service oil change they top off all your fluids and check for other items that are on your maintenance schedule. It’s like your safety net. Go in for an oil change on time, and let your service advisor help you keep track of the rest.

Some things are going to wear out along the way, things like alternators, water pumps, etc. But fixing those at Certified Auto Specialists is cheaper than a new car payment. And taking care of problems early means they have less time to mess with other things. It is like having high cholesterol – you don’t want to wait for a heart attack before you address it.
