What Every Owner Needs to Know
AUGUST 15, 2016 By POWERTRAIN PRO
The engine is the heart of every vehicle, and it’s the most expensive component to repair or overhaul. It does not matter what kind of vehicle you own or how you use it – the quality of the engine will play a major role in your overall satisfaction and your total repair costs.
The Ford 5.4-liter engine has been one of the most popular powertrains for more than a decade now, and over the years it has proven to be both reliable and fuel efficient. Even so, this engine’s owners have identified some common problems, and it is important to be on the lookout for the early warning signs.
The sooner you catch a problem with the Ford 5.4-liter engine, or any other one for that matter, the less costly the eventual repairs can be. Here’s what you need to know:
Fuel Pump Failure:
The fuel pump has a vital role to play, and unfortunately it has been a weak spot in 5.4-liter Ford engines thus far. More specifically, it is the fuel pump driver module that has been such a big issue. Over time, the fuel pump driver module can corrode, essentially eating a hole through its aluminum housing. Once the housing has become compromised and the delicate electronics have been exposed, it is just a matter of time before the fuel pump driver module fails.
Keeping a close eye on this driver module and watching for signs of corrosion is the best defense. You want to repair or replace the module at the first sign of corrosion, before the electronics are exposed and subsequently damaged.
Other Common Issues:
There have also been reported problems with the timing chain and tensioners as well as issues with the variable valve timing. If they go undetected, these problems can lead to the premature failure of the entire engine, or at least a big repair bill.
Unfortunately, problems with the tensioners, timing chain and other systems are not always readily apparent. The best defense is to have these items checked at least once a year by a mechanic who has experience with the Ford 5.4-liter engine. Premature wear on the timing chain, variable valve timing and tensioners can be subtle, and that is why working with an experienced Ford mechanic is so important.
Replacing Your Engine:
Should your engine fail, it’s important to be informed about your options for replacement. Many people do not realize that it is actually very cost effective to purchase a replacement engine and/or transmission and have it installed by a reputable local mechanic.
