Fuel Injection Basics for FORT WORTH

All modern FORT WORTH vehicles come with fuel injection systems, so it's a topic FORT WORTH drivers 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 vehicle have? There's one for each cylinder. So four, six or eight for most folks in FORT WORTH, TX. 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.

Westmoreland Transmissions can help FORT WORTH drivers 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 economy.

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 FORT WORTH with fuel prices as high as they are, but major brands in the FORT WORTH, TX, area have better detergents and additives and deliver consistent quality.

What about a good fuel filter? The fuel filter is 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 important to replace the fuel filter when your 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 FORT WORTH 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 FORT WORTH, TX, that can clean fuel injectors. They're best used 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 Westmoreland Transmissions in FORT WORTH. But putting the cleaner in the fuel tank after you've had Westmoreland Transmissions 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 vehicle may be ready for a fuel injector cleaning.

On Board Diagnostics for Your vehicle

Today we're going to talk about on-board diagnostics and the questions we hear from folks around FORT WORTH, TX, who need answers about diagnostic services. They want to know what diagnostics are, what's involved and what the benefits are. They really want to understand the value of diagnostic scans by a trained technician in FORT WORTH.

These are valid concerns. If you don't understand something it's really hard to know its value. Let's start with some history.

Since 1996, all cars and light trucks in FORT WORTH, TX, have been required to use a standardized diagnostic system to help repair technicians determine what's wrong with your vehicle. The diagnostic system works with the vehicle's Engine Control Module – the computer that controls many engine functions.

The computer monitors dozens of components and processes. Depending on what the sensors read, the computer will make adjustments to compensate for conditions and minor problems. When there is a condition that it can't adjust for, the computer will turn on the Check Engine light.

It is also called the 'service engine soon' light on some vehicles. The warning light signals you to get into your local service center so that the trouble code can be read and the problem can be fixed. Your service center will have a scan tool and powerful software that will help the technician diagnose the problem.

If you've searched for Check Engine light on the internet, you may have seen that you can buy an inexpensive scanner or go to an auto parts store to have the trouble code read to tell you exactly what's wrong.

That's a common myth. The code itself doesn't tell you what's broken. It starts you looking in the right place. It tells you what engine parameter is out of range – but it won't tell you what's wrong or how to fix it.

Let's say you think your daughter has a fever. You take her temperature and it reads 102 degrees F/38.9 degrees C. You've confirmed a fever, but you don't know what's causing it. Is it a 24 hour flu, an infection, appendicitis or leukemia? A fever is a symptom of all of these medical problems, but it takes a skilled physician's examination and additional diagnostic tests to find out what is actually causing the fever.

An example of a trouble code could be: P0133, which reads 'Bank 1 sensor 1 circuit slow response.' This means that the front oxygen sensor has a slow response time to changes in the air-fuel mix. If that's all you knew about cars, you would think your oxygen sensor was broken and would replace it. Now, it could be the oxygen sensor – but it could also be a bad or contaminated airflow sensor, exhaust leak, electrical problem, an intake manifold leak or any of a number of other things.

You can imagine a lot of oxygen sensors have been replaced because of that code. So the on-board diagnostics point the way to where the trouble lies, but it takes some skill and high-tech equipment to actually pinpoint the problem. The cheap scan tools that a consumer can buy do not have the ability to retrieve some of the operating history that's stored in the engine control computer. That history's very helpful in diagnosing the problem. Service centers like Westmoreland Transmissions invest a lot of money in high-end diagnostic tools to help solve the mystery and get you back on the road as soon as possible without replacing a lot of parts that don't need replacing.

So, on-board diagnostics provide a powerful starting place for a highly-trained, well-equipped technician to get to the bottom of your problem. When your Check Engine light comes on, get it checked at Westmoreland Transmissions. If the light burns steadily – don't panic. Get in to Westmoreland Transmissions soon to have the engine scanned. A flashing Check Engine light means that there is a severe engine problem. Get in as soon as you can – waiting too long can lead to very expensive damage.

And try to not drive at high speed or tow or haul heavy loads with a flashing Check Engine light.

Make an appointment with Westmoreland Transmissions to have your on board diagnostics analyzed.

Keep Your Tires Well Rounded in FORT WORTH: Tire Rotation and Wheel Balancing at Westmoreland Transmissions

Taking care of our tires is part of vehicle care for FORT WORTH drivers. We know they have to be replaced when they wear out, but tires also require some preventive maintenance. This maintenance will improve and extend the life of the tires, so it's well worth the effort and expense for FORT WORTH drivers to get it done. Tire maintenance includes keeping tires properly inflated, rotating tires and balancing wheels.

The recommended tire pressure for a vehicle's tires is printed on a sticker on the inside of the driver's side doorjamb. A lot of engineering goes into calculating the correct pressure, so it's an important number for FORT WORTH vehicle owners to know. Not following this recommendation can throw off the suspension system and can lead to tire damage. Underinflated tires wear out more quickly than properly inflated tires. Vehicles also get better traction and handling on properly inflated tires. Check your tire pressure at least once a week and add air if necessary.

Don't be tempted to add a bit of extra air to your tires when you fill them. Overinflated tires will cause the center tread to wear unevenly because of improper contact with the road. It will also affect the handling performance of your vehicle.

Rotating tires allows all four tires on a vehicle to wear evenly. Front tires get more wear than rear tires because they do most of the work on turns. Tire rotation allows all of the tires to spend time on the front of the car so they all experience the extra wear.

For most vehicles, tire rotation is simply a matter of moving the front tires to the rear and vice versa. Some vehicles, however, recommend a cross-rotational pattern. Other vehicles use asymmetrical tires, which means the right tires have to stay on the right side of the vehicle and the left tires on the left. Some vehicles use differently sized wheels on the front and back of the car and should not have their tires rotated.

What kind of rotation do you need? Check your owner's manual or talk to your service advisor at Westmoreland Transmissions. Your owner's manual will have information about how to rotate your vehicle's tires as well as letting you know how often you should get it done. For most vehicles, that's usually every 5,000 miles or 8,000 kilometers Your friendly and knowledgeable Westmoreland Transmissions professionals can also offer auto advice about tire rotation. A quick tire inspection can also indicate whether or not your tires are due to be rotated.

When it comes to tire maintenance for FORT WORTH drivers, wheel balancing is usually what we know least about. Balancing a wheel is necessary to keep it in constant contact with the road. If a tire is not balanced properly, it actually hops along the roadway. You can feel this hopping as a vibration in your steering wheel if the unbalanced tire is a front tire. You'll feel the vibration through your seat if a rear tire is unbalance. Properly balancing your tires is important and will extend their life span, improve handling and improve the safety of your vehicle. When you replace your tires, the new tires need to be balanced.

Never use different sized tires on the same axle of a vehicle. In other words, your front tires need to be the same size and your rear tires need to be the same size. Mixing sizes can lead to some serious handling problems for FORT WORTH drivers.

If you have an all-wheel drive or four-wheel drive vehicle, all four tires need to be the same size. If your tires are wearing out, you can sometimes make a new tire purchase fit within your budget by only buying two tires at a time. When you do this, the new tires should be installed on the rear of the vehicle. Rear tires are more in need of the traction than your front tires to avoid spinning out on slippery surfaces. If you drive a vehicle around FORT WORTH, you need tires, so you need to know how to care for them. The safety of your vehicle can depend on the condition of your tires.

Battery Replacement for Your vehicle

Modern vehicles in and around FORT WORTH run on 12 volt electrical systems. 12 volts is enough to get the job done for FORT WORTH drivers without having so much power that there is danger of electrocution. But today's vehicles have more electrical components and do-dads than ever before. This really strains your electrical system, making it hard for the battery to keep up. Think about it: electric seats, seat heaters, power locks windows and sun roofs. And then us TX drivers have all the power outlets for our cell phones, computers and DVD players.

We also have navigation systems and powerful stereos. Plus there are all the engine and transmission computers, traction control, stability control, anti-lock brakes, sensors and on and on. Even the security system is running off the battery while the car is turned off.

Fortunately, battery technology has given FORT WORTH drivers resilient batteries that are able to meet these strenuous requirements. But the fact is, batteries just wear out over time. Eventually, every battery gets to the point where it cannot hold enough of a charge to start your vehicle. Sometimes batteries need to be replaced because they have just worn out. Or, in other cases, they have developed a leak which makes it even more important to get it replaced.

Special safety precautions are taken when working with batteries at Westmoreland Transmissions in FORT WORTH, TX. These precautions also apply to anyone who is poking around the battery. Batteries contain sulfuric acid that can damage your eyes and burn your skin, so safety glasses and rubber gloves are a must for any FORT WORTH resident working with their battery. Be careful to not spill acid on your clothes or the vehicle's paint. Of course, avoid short circuiting the battery as well.

Sometimes there is quite a price range in FORT WORTH auto part stores for batteries that will work in a particular car. Think of it as "good," "better" and "best." More expensive batteries have a longer warranty and are guaranteed to last longer. As with most things, paying a little more up front saves in the long run for FORT WORTH drivers.
