Diesel Injectors

Diesel Injectors in Goodyear and Surprise, AZ


What are Injectors and what do they do for my Diesel?

Diesel Injectors deliver (i.e. injects) fuel directly into the cylinders, mixing with pressurized air for combustion. There is a direct correlation between how many cylinders you have and how many Injectors you have. For example, if you have 8 cylinders, you will have 8 Injectors.

What can I do to get the full life out of my Injectors?

Fuel quality plays a big part in the efficiency and life span of your Injectors. Regulations over the years have reduced the amount of lubricity by limiting levels of sulfur and cetane in diesel fuel. In order to help preserve your injectors, you should use a diesel fuel additive and make sure to stay up on your preventative maintenance, such as a fuel injection cleaning and changing your fuel filters regularly.

What is Diesel Fuel Additive?

Fuel additives were introduced to help compensate for what has been removed from diesel fuel over the years. Specifically, fuel additive brings the lubricity and cetane levels back up to help your diesel engine run smoother and help you get the full life out of your fuel system. Fuel additive is available for purchase at several places, including Champs Family Automotive in both Surprise and Goodyear. Fuel additive is added directly to your fuel tank and should be used EVERY time you fill your tank to ensure you get the most benefit from the product. Diesel Fuel additive will help lubricate your engine, assist with combustion, create the heat it needs to clean out the catalytic systems, and EGR (Exhaust Gas Recirculation), and DPF (Diesel Particulate Filter) systems.

If you only use fuel additive once in a while, it most likely will not help your diesels efficiency and performance. For example, let’s say you have a Ford F350 which hold 38 gallons of fuel and gets hypothetically 20 miles to the gallon. This would equate to roughly 760 miles per tank. Now if you only used fuel additive in every other tank, you’re now running your diesel nearly half the time without the proper chemicals it needs to keep it running smoothly and efficiently. This can cause premature wear and tear to your fuel system.

Diesel Fuel Additive

Do all Diesel vehicles need to use fuel additive?

We recommend all diesel vehicles, especially the newer diesel vehicles, always use fuel additive in every tank of fuel they put in their vehicle. Always read the instructions on the additive container to identify how much additive your specific diesel vehicle needs. If you are not sure if you should be using fuel additive or if you would like more information about what fuel additive can do for your diesel, contact us at Champs Family Automotive.

Fuel Injection Cleaning

What is Fuel Injection Cleaning?

Fuel Injection cleaning is a process that cleans the tips (Nozzle, Pintal) of the injectors and removes carbon build-up. When injectors are clean and free from carbon build-up, they can inject fuel properly which allows your diesel to work efficiently. If the injectors are not clean, you can get smoke from the tail pipe, a rough idle, or in some cases a check engine light may turn on. We’ve seen injectors get so dirty and built up with carbon that they don’t spray fuel correctly and instead they begin to spray like a water jet, continuously spraying on one defined area. This can cause holes in pistons, and other places, depending on how and where the fuel is being sprayed. A clean, properly working Injector will actually spray more of a mist into the cylinder, not a jet stream of fuel. Fuel injection cleaning can prevent premature failure in your injectors and help you save time and money on costly repairs. Always remember, fuel injection cleaning will not repair an injector or repair damage that has already been done by lack of maintenance. Fuel injection cleaning is a preventative maintenance procedure and will not overcome Injector design issues or nature failure of Injectors.

How often should I have a Fuel Injection Cleaning done?

Typically, we recommend having your injectors cleaned at least once a year. This does depend on your driving habits and your use of Fuel Additive.

How will I know if an injector is bad?

In most cases, there are no warning signs that an injector(s) is going bad. Usually, by the time you notice something is wrong with your vehicle and it’s related to injectors, it’s too late and an injector needs to be replaced.

If injector(s) fail, can I only replace the one(s) that failed, or should I replace all my injectors at the same time?

The short answer is yes, you can only replace the injector(s) that have failed. Typically, replacing injectors is very time-consuming process. Depending on why your injector(s) failed, we may recommend replacing just the injector that failed, a bank, or all injectors. There are a lot of variables to consider when trying to determine what injector or injectors should be replaced. Our technicians use experience, training, and state of the art equipment to determine where the problem may be and how many injector(s) should be replaced. We always work with our customers to help them make the best educated decision about their vehicle.

Do I have to use OEM Injectors on my Diesel?

Diesel injectors are proprietary, and the manufacturers own the specific rights to their products. Injectors for your vehicle have to meet specific specifications. Buying aftermarket injectors may be cheaper, yes, but they’re cheaper for a reason. After market injectors may work, but they may not work for long, or could cause other problems. Aftermarket injectors are not manufactured or engineered to the same exact specifications as OEM Injectors are, therefore, we do not recommend using aftermarket injectors.
