Fuel Injection Basics For Brea

All modern Brea vehicles come with fuel injection systems, so it’s a topic La Habra auto owners need to know something about. The mighty fuel injector is a valve that delivers the gas or diesel fuel to the right place, in the right amount, at the right time; to be mixed with air and burned in the engine.

So how many fuel injectors does your car have? There’s one for each cylinder. So four, six or eight for most folks in Brea, California. Some vehicles have 10 or 12 cylinders. The engine control computer makes adjustments to the fuel injector as it monitors the engine and other sensors. Fuel injectors are a pretty high-tech.

Jax Auto Repair can help La Habra motorists with a fuel injector cleaning service. What’s the benefit? In order to work right, the fuel injectors have to deliver the fuel at a precise pressure at a very precise time. It’s important that the fuel is sprayed in a particular pattern as determined by the engine design.

Over time, varnish can start to build up in the fuel injectors, effecting the pressure, pattern and timing of the fuel charge. The result is that the fuel doesn’t get burned as efficiently as it could. That robs performance and hurts fuel efficiency.

What about dirty fuel – how does that affect the fuel injectors? The fuel injectors are the last stop in the fuel system. It starts at the fuel tank. Frankly, the best way to keep your fuel injectors working well is to use high quality fuel. It’s tempting to shop for bargains in  La Habra with fuel prices as high as they are, but major brands in the Brea, California area have better detergents and additives and deliver consistent quality.

What about a good fuel filter? The fuel filter is an important component of the fuel system. Its job is to filter out the dirt and rust that collect in the fuel tank. If it’s clogged up, the dirt will bypass the filter and head upstream to the fuel injectors.

It’s vital to replace the fuel filter when your auto manufacturer recommends it. That’s part of a comprehensive fuel system cleaning.

There are different kinds of fuel injection systems. Port fuel injection systems, the kind most gasoline engines have, operate at 60 pounds per square inch. The injectors for the new gas direct injection engines Brea drivers are starting to see require 10 to 30 times as much pressure. And some diesel engines for passenger vehicles have injectors that operate at 30,000 pounds or more per square inch. There’s no room for dirt and gum in a precision part like that.

There are a lot of good products available in Brea, California that can clean fuel injectors. They’re best used by Brea auto owners to prevent fouling in the fuel injectors. Many can’t clean a seriously gummed up injector – that requires a professional deep cleaning, like those we offer at Jax Auto Repair in Brea. But putting the cleaner in the fuel tank after you’ve had Jax Auto Repair take a look at your fuel system will help keep it clean. Be sure to read the label for directions.

Give us a call if you think your sedan may be ready for a fuel injector cleaning.

Water Pump

Your cooling system is very important. It circulates coolant through the radiator and your engine to protect your car from overheating. There are five main components to the cooling system:

  • the radiator
  • the radiator cap
  • the hoses
  • the thermostat and
  • the water pump

The cooling system is important for Brea drivers. It circulates coolant through the radiator and your engine to protect your sedan from overheating. There are five main components to the cooling system:

the radiator
the radiator cap
the hoses
the thermostat and
the water pump

The water pump’s like the heart of your cooling system, circulating the fluid throughout your sedan. It’s a small pump that’s driven by the engine; usually by belt, but sometimes by a chain or gear.

The water pump only operates when the engine’s running. Water pump failure is pretty routine. We see it often at Jax Auto Repair. Some start failing at around 40,000 miles, but most fail by 100,000 miles. Consult your automobile manufacturer’s owners’ manual or friendly Jax Auto Repair service advisor to see what’s recommended.

Since a water pump either works or it doesn’t, you need to change it when it fails. Water pumps fail in one of two ways: the bearings fail or they begin to leak. It’s possible to have a leak from a cracked water pump, but it usually leaks at the gasket where it attaches to the engine.

So how can Brea motorists tell when the water pump is failing? If you can hear a low-pitched grinding sound coming from the water pump – it’s got a problem. If you can see coolant in that area, you’ve got a leak.

Some water pumps are driven off the timing belt. They might be under a plastic cover so you can’t see the water pump. Look for coolant on the driveway. If you see some, have your Jax Auto Repair service specialist check it out.

Most timing belts need to be changed at 60,000 miles – some longer. It’s a good idea to change your water pump at the same time if it’s one of those that’s driven off the timing belt. To start with, 90% of the work’s already done with the timing belt change. And, if you don’t, and develop a leak later, you’ll have to change the belt again along with the water pump because the belt will have been contaminated by the leaking coolant.

Brea drivers can replace a failed water pump with a brand spankin’ new one or with a rebuilt pump. Rebuilt will save you some money, but ask your friendly Jax Auto Repair technician what he thinks. Don’t feel too bad if your water pump gives out. They will all wear out eventually. Your Jax Auto Repair service professional can get you back on the road and on with your life.

Questions To Ask Your Brea Service Advisor

We find that a lot of Brea service and repair at Jax Auto Repair are a little tentative when they talk with their automotive advisors. They want to ask questions, but don’t want to be embarrassed or to seem pushy. Cars are very complicated and there’s more to know about them than most of us have the time to learn. Maybe it’s because cars have become so much more reliable that the average person just doesn’t need to know as much to keep their vehicle on the road.

You know, your local hospital has a Patient’s Bill of Rights that they post throughout the hospital. We think our Brea automotive service customers also have a right to ask any question they need to understand what is wrong with their car and what it will take to fix it. They need to feel free to ask the cost and benefits of recommended services. And they certainly have a right to understand the financial end of the transaction.

It’s all about the communication. It’s a little harder when you’re trying to find the right service center in Brea. But once you’ve developed a relationship, the communication should come easier.

What are some of the barriers to communication? Well, let’s go back to the medical example. When your doctor’s explaining something to you, it’s something that she understands very well and is very familiar with. So she may use jargon you don’t understand or that you don’t have the education and training that’s foundational to understanding what she’s trying to explain.

So you fall behind and get frustrated.

It can be the same with your Brea automotive service advisors. Most of them are very busy trying to service and fix cars to get their customers back on the road. So, just ask when you feel you need more information.

Financial related issues seem to be most frustrating to customers. If you’re not sure, ask what the payment policies are. For example, there’s a big difference between giving your car a quick once over and doing a thorough inspection. Diagnosing a problem may take quite a while. Make sure you know what’s done as a courtesy and what has a fee. Remember, you still have to pay for the office visit even if the doctor says you only have a cold.

Communication is a two way street. If you have some real budget concerns, ask your Brea service advisor what he can do. He can give you priorities and options. He can tell you what needs to be taken care of right away for safety or financial reasons. Then you can work out a plan for when to get the rest done. He can also help you with options on the parts. The preference is to always use a high-quality part with a reputation for reliability. But if money is real tight, he might be able to find a rebuilt part or a used part. He should tell you the difference in the guarantee for the part so you can make a good decision.

Ask about warranties for parts and labor. Be sure to get all the paperwork you need to make a possible claim in the future. Your service center and its technicians stand behind their work and want you to understand precisely what that means.

Be sure to ask for and keep a detailed explanation of all the work that’s done on your vehicle. These records will help you keep track of service, warranties and document the good care your vehicle has received when the time comes to sell it.

Tire Tread Depth for Brea, California Drivers




Driving on bald tires is like playing roulette. Though you may be fine today, eventually your luck is going to run out.

The Feds don’t have any laws for tread depth, but 42 of the states, and all of Canada, do have regulations. They consider two-thirty-seconds of an inch to be the minimum legal tread depth. Two other states, including California, consider one-thirty-second to be the minimum and six states have no standards at all. Call us at Jax Auto Repair; (just call (714) 529-2886) to find out what your requirements are in the Brea, California area.

Since 1968, U.S. law has required that a raised bar be molded across all tires. When tires are worn enough that this bar becomes visible, there’s just 2/32” of tread left. But does that older standard give Brea car owners enough safety?

Consider this: Consumer Reports recommends tire replacement when tread reaches 4/32”. And the recommendation is backed by some very compelling studies. Now before we go into the studies, you need to know that the vital issue is braking on wet surfaces.

We tend to think of the brakes doing all the stopping, but Brea auto owners also need to have effective tires to actually stop the car. When it’s wet or snowy in Brea California, the tread of the tire is critical to stopping power.

Picture this: you’re driving in Brea over a water-covered stretch of road. Your tires actually need to be in contact with the road in order to stop. That means the tire has to channel the water away so the tire is actually contacting the road and not floating on a thin film of water – a harmful condition known as hydroplaning. When there’s not enough tread depth on a tire, it can’t move the water out of the way and you start to hydroplane.

This is where the studies come in. We think Brea car owners will be surprised. A section of a test track was flooded with a thin layer of water. If you laid a dime flat on the track, the water would be deep enough to surround the coin, but not enough to submerge it. 

A car and a full-sized pick-up truck were brought up to 70 mph and then made a hard stop in the wet test area. Stopping distance and time were measured for three different tire depths. First, they tested new tires. Then tires worn to legal limits. And finally, tires with 4/32” of tread were tested (the depth suggested by Consumer Reports.)

When the car with the legally worn tires had braked for the distance required to stop the car with new tires, it was still going 55 mph. The stopping distance was nearly doubled. That means if you barely have room to stop with new tires, then you would hit the car in front of you at 55 mph with the worn tires.

Now with the partially worn tires – at the depth recommended by Consumer Reports – the car was still going at 45 mph at the point where new tires brought the car to a halt. That’s a big improvement – you can see why Consumer Reports and others are calling for a new standard.

Now without going into all the details, let us tell you that stopping the truck with worn tires needed almost 1/10 of a mile of clear road ahead to come to a safe stop. How many Brea motorists follow that far behind the sedan ahead? Obviously, this is a key safety issue.

The tests were conducted with the same vehicles, but with different sets of tires. The brakes were the same, so the only variable was the tires.

How do Brea motorists know when their tires are at 4/32”? Well, it’s pretty easy. 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 tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.

Now you may remember doing that with pennies. But a penny gives you 2/32” of an inch to Abraham Lincoln’s head. The quarter is the new standard – 4/32”.

Tires are a big ticket item and most drivers in Brea, California want to get thousands of miles out of them. Just remember: driving on bald tires is like playing roulette.

Have Mr. Washington look at your tires today. If he recommends a new set, come see us at Jax Auto Repair in Brea.

Tracking True In California: Wheel Alignment In Yorba Linda

Wheel alignment is often overlooked by busy Yorba Linda and Buena Park auto owners until serious tire damage has been done. One wheel can be knocked out of alignment by hitting a curb or pothole on a La Habra freeway or surface street.

When a vehicle’s out of alignment, one or more of the wheels does not track true and pulls against the others. This causes several serious problems. First off, the tires will wear out faster and will need to be replaced prematurely. It could also lead to expensive sedan suspension problems.

Tracking True In California: Wheel Alignment In Yorba Linda

But the big issue for Yorba Linda, Buena Park, and Brea auto owners is safety. When your sedan wheels are out of alignment, the vehicle will pull to one side, which could lead to an accident. When you’re out of alignment, you should have it taken care of right away at Jax Auto Repair in Brea.

When undergoing an alignment service at Jax Auto Repair, your sedan is put on an alignment rack where the tires, steering and suspension parts are checked for damage. Then the alignment is charted and checked against the factory settings.

Precision adjustments are made to bring the wheels back into alignment. This gets all four wheels going in exactly the same direction.

Buena Park auto owners should be aware of the signs of alignment problems. These include the car pulling to one side. Also, the steering wheel may not be centered when you’re going straight. If you see the edges of one or more tires rapidly wearing down, you should have your La Habra service center look it over. If you’ve been in an auto accident in California that involved a wheel, you should get your alignment checked.

Obviously, a big jolt can seriously knock things out of alignment, but Yorba Linda drivers also need to understand that a series of smaller ones can add up.

That’s why vehicle manufacturers recommend periodic alignment checks. If your sedan owner’s manual doesn’t specify, once a year might be appropriate. Or check with Jack Tafreshi or your service advisor at Jax Auto Repair in Brea.

One thing’s for sure: the cost of the alignment at Jax Auto Repair is cheaper for Yorba Linda auto owners than having to buy a couple of new tires because of neglect.
