Diesel fuel injectors in Fredericktown, OH face several vulnerabilities due to both environmental and mechanical principles, and our shop has to repair or replace them often. This can be an expensive job, and people often inquire about how to prevent fuel injector failure so they don’t have to absorb that cost again. Here is an explanation of why this essential component fails, and the steps you take to avoid that ordeal.
Why failure occurs
The inside of a diesel engine is a harsh environment, and the injectors receive the worst treatment of all. They frequently fall apart due to structural integrity and fuel quality. Often, these two elements work in tandem to cause the future calamity.
Structural issues involve worn injector balls, leaking feed tubes and blown seals. If there are any cracks, those will eventually lead to failure, too. These are not manufacturer defects, though. Normal wear and tear, especially with work trucks, is the common culprit, but one other item makes the whole scenario worse: fuel quality.
While it is slowly improving, diesel fuel is not as clean or efficient in the U.S. as its counterpart in Europe. This means more debris enters the fuel system, setting up a continuous test against the injectors. This leads to buildup that eventually eats away at the injectors themselves. Without preventative action, you will discover fuel leaks and your car will stall. The first symptom that your injectors are struggling is a car or truck that is difficult to start.
How to prevent
Fuel system maintenance is a vital part of preventing a fuel injector failure. Start with keeping the fuel system clean. Fill your tank only at reliable sources of diesel fuel and change fuel filters regularly. If you are on a job site, avoid filling from the portable tanks, as that fuel is often of a much lower quality or has been sitting around for a while collecting dirt.
When it is time to replace parts, use OEM certified performance diesel parts. You may pay more for this higher quality, but it will pay off in the long run with fewer repair bills and more efficient operation. If you use remanufactured or aftermarket parts, only do so with the endorsement of an experienced diesel mechanic.
If a vehicle is going into storage, start it occasionally so moisture does not corrode the components. Also put in fuel additives, as that will help stabilize any fuel still in the tank and keep it from becoming too dirty.
Older engines do not face this weakness as frequently because they do not generate as much air pressure. Their fuel passages are also larger, meaning fuel quality does not affect them as much. That presents the unfair reality that this is an issue you need to be aware of more for your newer vehicles.
