Common FORD 3.7L V6 Engine Problems
The ford engines have proven itself reliable for many years, the fact that we can all agree. But like every other product, ford engines are not without flaws.
Also, Ford, as a brand, has faced several recall cases due to part defects, which have caused doubt among customers.
Unfortunately, the ford 3.7L V6 happens to fall among the engine models with a few design flaws and problems, which can be detrimental to the engine’s lifespan. Let’s take a quick look at a few of the defects.
01. The water pump failure
The water pump is usually not a part to worry about. But the location and the chain component driving the ford 3.7L v6 puts it up for serious concerns. The water pump is located behind the engine front cover.
The position of the water pump necessitates an engine drop in the event of a water pump failure.
More worrisome is the fact that the chain-driven water pump also times the chain sprocket.
However, if the water pump bearing fails, there is definitely going to be a shift in the timing center that can cause severe damage to the engine.
Coolant leakage as a result of water pump failure ends up inside the engine resulting in total engine damage if not resolved early enough. The fault most times, do not give any prior warning in the form of noise or leakage.
It just happens as a sudden breakdown, mostly on highways, which is quite dangerous.
Although the water pump was built to last the entire lifespan of the engine, it still fails due to various reasons like poor cooling system maintenance, a defective pump, or poor designs.
The chain-driven water pump in Ford’s 3.7L V6 engine has been a topic of debate on various forums and platforms like youtube.
This particular engine flaw has raised severe questions amongst the 3.7 v6 owners with models before 2011.
Ford was sued in October 2018 by the owner of a 2008 Ford Edge model for alleged engine failure due to water pump issues.
Symptoms of a failing water pump
- Coolant leakage
- Overheating engine
- Steam coming from the engine
02. Ticking noise on cold start
Another peculiar problem associated with the 3.7L V6 engine is the ticking sound coming from the driver’s side cylinder head.
This issue has raised lots of concerns from various users who are concerned about the resultant effects of this sound and what could cause it.
Although Ford initially alleged that the ticking noise had no adverse impact on the engine, the company later released TSB 11-8-26 to help solve the problem.
If you notice this ticking noise in your engine, I advise you approach your dealership with the TSB 11-8-26 for Ford recommended step by step approach to fixing it.
03. Oil leak-out issue
The oil leakage issue is also another 3.7L V6 engine issue that is discussed on almost every 3.7L V6 forum and Youtube auto channels. The oil leaks are most often dripping from the oil filters.
A simple replacement of the oil filter and the gasket can be a simple solution in most cases. But in sporadic cases, it could be a sign of a severe engine mishap.
FORD F-150 3.7L V6 Engine Problems
Although the problems facing the 3.7L V6 engine are similar throughout all the ford models using it, it is necessary to single out the F-150.
The F-150 has maintained its premier position as America’s favorite commercial vehicle for 40 years straight.
The 3.7L V6 engine running the F-150 is robust and efficient in every aspect and yet has an excellent fuel economy.
The major problems facing this model is the same as already discussed above. However, there are cases of some noise coming from the engine like:
the engine makes a rattling noise while at idle and also in gear, but the sound seems to disappear when the vehicle is accelerated.
This noise has been a source of serious worry for most of the 3.7L V6 engine owners.
However, changing the alternator and the cam synchronizer and replacing the belt & tensioner could be your engine’s turning point. A typical example of the noise is heard below this video.
Finally, there are no engines that are totally flawless in design and configuration.
To maintain a good engine it is good to keep to routine maintenance processes. Check out for any signs of overheating, have a regular check on the oil, air filters and replace worn out parts.
