Autowave Inc On Your Serpentine Belt

September 27, 2011 autowaveinc No comments

Today we’re going to be talking about serpentine belts for our Huntington Beach 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 Huntington Beach 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 Huntington Beach 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 Huntington Beach 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.

Autowave Inc 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 Huntington Beach 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 Huntington Beach 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 Huntington Beach California traffic.

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

How Your Check Engine Light Works

September 23, 2011 autowaveinc No comments

Have you ever had an experience like this in Huntington Beach California? You drive through the one of those automatic car washes. When you get to the end, where the dryer is blowing, your check engine light started flashing!

You fear the worst, but within a block or two, the light stopped flashing, but stayed on. By the next day, the light was off.

You wonder; “What was going on?” Well, it’s actually a good lesson in how the Check Engine light works.

Your air intake system has a sensor that measures how much air is coming through it. When you went under the high-speed dryer, all that air was blasting past the sensor. Your engine computer was saying, there shouldn’t be that much air when the engine is just idling. Something’s wrong. Whatever’s wrong could cause some serious engine damage.

Warning, warning! It flashes the check engine light, to alert you to take immediate action.

It stopped flashing because once you were out from under the dryer, the airflow returned to normal. Now the engine control computer says the danger is past, but I’m still concerned, I’ll keep this light on for now.

Then the Check Engine Light goes off in a day or two.

The condition never did recur, so the computer says whatever it was, it’s gone now. The danger is past, I’ll turn that light off.

Now a flashing check engine light is serious. You need to get it into our Huntington Beach California shop as soon as possible. But if it stops flashing, so you have time to see if the problem will clear itself or if you need to get it checked. How does the computer know when to clear itself?

Think of it this way. The engine control computer is the brain that can make adjustments to manage the engine. Things like alter the air to fuel mix, spark advance, and so on. The computer relies on a series of sensors to get the information it needs to make decisions on what to do.

The computer knows what readings are in a normal range for various conditions. Get out of range, and it logs a trouble code and lights up the check engine warning.

The computer will then try to make adjustments if it can. If the computer can’t compensate for the problem, the check engine light stays on.

The computer logs a trouble code. Some people think the code will tell the technician exactly what’s wrong?

Actually, the code will tell the technician what sensor reading is out of parameters. It can’t really tell you why, because there could be any number of causes.

Let’s say you’re feeling hot. You get your heat sensor out – a thermometer – put it under our tongue and in a minute or two you learn that you have a fever of 104 degrees.

You know your symptom – a fever – but you don’t know what’s causing it. Is it the flu, a sinus infection or appendicitis?

You need more information than just that one sensor reading. But it does give you a place to start and narrows down the possible problems.

There are reports on the internet telling you that you can just go down to an auto parts store and get them to read your trouble code or buy a cheap scan tool to do it yourself.

There are two problems with that. First, the computer stores some trouble codes in short term memory, and some in permanent memory. Each manufacturer’s computer stores generic trouble codes, but they also store codes that are specific to their brand.

A cheap, generic scan tool, like you can buy or that the auto parts store uses, doesn’t have the ability to retrieve long-term storage or manufacturer specific codes. Your Huntington Beach California service center has spent a lot of money on high-end scan tools and software to do a deep retrieval of information from your engine control computer.

The second problem is that once you’ve got the information, do you know what to do with it? For example, a very common trouble code comes up when the reading on the oxygen sensor is out of whack.

So the common solution is for the auto parts store to sell you a new oxygen sensor, which are not cheap, and send you off on your way. Now your oxygen sensor may indeed have been bad and needed replacing. But the error code could have come from any of a dozen of other problems.

How do you know the right solution? Back to the fever analogy, do you need surgery or an aspirin? Leave it to the pros at Autowave Inc. Give us a call at (657) 666-0157 and let us help you resolve your check engine light issue.

ICE – In Case Of Emergency In Huntington Beach California

September 15, 2011 autowaveinc No comments

Sometimes the unthinkable happens in Huntington Beach California. A terrible accident and those involved aren’t able to provide rescuers with emergency contact information.

You have people in the Huntington Beach California area who you’ll want to be contacted to arrange help, give consent to treatment, and inform paramedics of medical conditions, allergies or medications.

Too often, our California police and rescue workers must sift through pockets, glove compartments, wallets, purses and cell phone directories for clues – often wasting precious time.

A brilliantly simple solution is now spreading around the globe: ICE. ICE – standing for In Case of Emergency, is a way to identify emergency contacts in your cell phone directory.

Simply put ‘ICE’ before a contact name in your cell phone, like ‘ICE – Dad’, ‘ICE – Nancy’, or ‘ICE – Doctor Roberts’. Rescuers will be able to quickly identify your emergency contacts, saving valuable time.

Bob Brotchie, a Cambridge, England paramedic came up with the idea and started a promotional campaign in England in 2005. This powerful idea is now being heavily promoted in Huntington Beach California and in other countries. Rescue workers all know of how many times they are unable to find a wallet or purse on an accident victim, yet they are seldom without their cell phone.

There are national and worldwide disaster databases, but participation can cost up to two hundred dollars a year. ‘ICE’ is free to the 276 million cell phone users in the U.S.

It is easy and just takes a few minutes to designate some ICE contacts in your cell phone. Remember to keep the listings current.

Please join Autowave Inc in getting the word out. Help us put Huntington Beach California on ICE!

Service to Improve Fuel Economy

September 6, 2011 autowaveinc No comments

The price of gas has got everyone talking. It seems that people who need a bigger vehicle to carry family and gear, or provide four wheel drive, are especially hit hard. That is why we thought it would be good to review some things that anyone can do to improve fuel economy.

First let’s start with how we drive. People may not realize that they can really save on gas by just changing a few driving habits. One of the biggest is jackrabbit starts – you know, flooring the gas as soon as the light turns green. That really wastes a lot of fuel. Building up your speed at a slower pace uses less fuel and is easier on your engine and drive train. And don’t drive with one foot on the brake. That’s also a drag on fuel economy, and it wears out your brakes faster too.

Another thing is to drive slower – but only when it’s safe. Sometimes on the highway we drive an extra five … ten . . . twenty … over the speed limit. We do it to save time, but it only saves a few minutes out of maybe an hour long drive, and we may use 10 to 15 % more gas. Just leave a little bit earlier, save some money and arrive more relaxed.

You can also try and group all of your errands for the day into just one trip, rather than several. If you can put off a trip today that can be combined with one tomorrow – you can save some time and money.

Using your cruise control can save money too. Driving at a constant speed really improves fuel economy. Be sure to only use your cruise control under safe conditions – you can look in your owner’s manual for some good tips on using your cruise control.

Did you know that reducing the weight in your vehicle saves gas? Clean out the trunk or back seat from time to time so that you are not paying to carry around a lot of stuff you do not need in the car. If you live where there is snow and ice, clear it off your car. They add weight and mess with aerodynamics too.

Another tip is to avoid long idle times, which includes warming it up when you start. Modern engines do not require a long warm up to get going – just take it easy for a couple of miles.

Be sure to get a new gas cap if yours leaks or is worn.

Now, let’s start talking mechanical. Bottom line – the better you maintain your vehicle, the less fuel you will use. It all adds up in a big way. For example, replacing your dirty engine air filter will pay for itself in fuel savings before your next oil change – and will keep saving you money after that.

A clean, well-maintained fuel system really pays big dividends. A clogged fuel filter wastes gas. So does a dirty fuel system, grimy fuel injectors and plugged up PCV valves. A fuel system service decreases the gas you use, and increases the power – so you can’t go wrong with that.

Some of us ignore our Check Engine light. But fixing the problem that caused the light to come on will usually save some fuel as well. It may be a bad oxygen sensor that can really rob your fuel economy.

And, it may be time for a tune-up. Tune-ups should improve your fuel economy. Don’t overlook the routine maintenance items, like scheduled oil changes, transmission and cooling system service. Dirty or low fluids actually use more fuel. Just look at your manufacturer’s recommended service intervals in the owner’s manual, or ask your Autowave Inc service advisor for the schedule.

Don’t forget your tires. Underinflated tires waste gas. And if your wheels are out of alignment you won’t get the economy you need.

None of these things are very complicated or expensive to stay on top of. When you maintain your car properly, you save gas today, and prevent costly repairs tomorrow.
