The 3 Most Common Ford F-150 3.7 Liter V6 Problems

Learning about what causes to fail your Ford 3.7 Liter V6 Cyclone engine

We shall now be focusing on the three issues I outlined in the intro above.

A detailed analysis of the problem will surely help you.

1. Failure Of The Water Pump


The water pump failure is one of those that plague many Ford engines. This does include the 3.7L V6 engine.

Normally the issue can be resolved without any difficulty, thanks to the easy access to the location of the pump, but in the case of the 3.7L engine, buyers had some questions.

The water pump on the 3.7L V6 has been designed so that if it fails, the engine will stop working. This is because the company has used a chain-driven water pump.

The same pump is also used to time the chain sprocket. Ford made the process of making this pump functional complicated.

This has never been seen before on an engine, and with a part as simple as a water pump.


So, what will happen if the water pump leaks or fails?

Many issues can arise that can deal light or heavy damage to the V6 engine.

For example, if the bearings on the pump fail, you are looking at major damage to the engine, which is a consequence of a shift in the timing center.

That is not all. Coolant leakage due to a failure of the water pump can also cause damage to the engine.

The leakage can also cause sudden engine shutdown on a highway, which is quite dangerous for not only the driver and the passengers in the vehicle but the vehicles around it too.

There are a few reasons that can cause the water pump to fail. The main cause for this issue is the poor design.

Ford should have designed the water pump to be able to handle intense usage. This ranges from being able to handle shocks and impacts to the high engine temperature.

Unfortunately, they did not do that, which caused the pump to create issues for users.

Ford has had a history of creating at least one part that is not up to par. It needs to focus on them to ensure buyers don’t end up with a damaged engine.


The main symptoms of a failing water pump are as follows:

  • Leakage of the coolant into the engine
  • Engine overheating due to insufficient cooling
  • Engine outputting steam

So, what can a person do to address this issue?

If you are lucky and the vehicle has not stopped on the road, you should park it at the side and call a towing service.

You should take the truck to a nearby mechanic to get the problem professionally diagnosed and fixed. With any luck, you can expect minimal damage to the engine.

2. Ticking Noise When The Engine Is Cold Starting

Another issue that has bothered many users is the ticking noise coming from the engine when users are trying to cold start their engines.

The sound itself is not the problem, but there could be an underlying problem that scared many customers.

Ford’s Response

Due to the growing concerns of consumers about this issue, Ford had to issue some sort of response to calm the public down.

They assured F150 owners that the V6 engine, with the ticking noise, had no impact on the performance, nor was there an underlying problem.

But a few months later, the company issued a recall program by the name of TSB 11-8-26.

As the name states, the service bulletin was valid for all F150s manufactured on or before the 28th of August 2011.

The company clarified that the noise originated from the cylinder head that is on the driver’s side.

The bulletin instructed the dealerships to make the appropriate replacements, so users would not experience the same thing again.

This was strange behavior on the company’s part. The double statements and the recall are something that definitely would have gotten many users curious.

Regardless, the company did take a step in the right direction in the end.


To confirm that your truck has the same issue, you have to start your engine at various times of the day. If the issue is present, then it will tick when you could start in the morning.

The ticking should last around 10 minutes. You should also start the engine when it is warmed up. The sound should not be present.

If everything happens the same way it is written, then you can drive up to the dealership to get the engine repaired without any additional cost.

If you are visiting the dealership, I recommend getting a full check-up just in case.

You can never be too safe, can you?


Fortunately, as Ford stated, the issue does not do any damage to the engine. You can keep driving around without any worry that the V6 engine will cause any further issues.

But, if your truck meets the service bulletin requirements, I would advise that you get the repair done because it will not cost you anything.

You do have to present the bulletin at an authorized dealership to get the free repair.

So, to confirm that you are eligible for a free repair:

  • You should confirm if the knocking and ticking noises are not persistent.
  • The engine’s manufacturing date is before 26th of August 2011.

If the engine checks these boxes, then you can go ahead and get the repair done without any charges.

Ford made sure that users did not have too many complaints, and they stepped in to make their mistake right.

3. Unexpected Oil Leakage

The final problem of this article is yet another one that must not be taken lightly.

Owners of trucks with the 3.7L V6 engine under the hood complained that their engine abruptly started to leak oil.

So, let’s see what the source of this problem is and how users can address it.

Cause Of The Leakage

There are two possible reasons for the oil leaking from your engine. Most users noted that the leakage was from the oil filter.

If that is the case, then you only have to replace the oil filter and gasket. The replacement for both is quite cheap, and you can do it at home or via a mechanic.

But that is not the only reason that can cause an oil leak on the 3.7L V6 engine. Some buyers reported that this could be caused due to a defective oil seal too.

The main seal on the engine can fail, which can cause oil leakage. The speed of the leakage depends on how much the seal is damaged.


An oil leak can be identified quite easily. The easiest way to check for a leak is to look for droplets on the ground on which the truck is standing.

Oil has a distinct dark color, so it will be easy to spot. Another thing that some of you might notice is overheating of the engine. Oil also transfers heat, which keeps the engine cool.

If there is insufficient oil, then the 3.7L engine may overheat quickly, which can be observed by the indicator light that turns on.

Finally, another symptom of oil leakage is that the vehicle stops abruptly, or it refuses to start at all. If that is the case, then it may be that there is oil leakage.

A vehicle refusing to start can be a symptom of some other underlying issue, so this is definitely not a proper test.

How To Address The Problem

If you suspect a sudden oil leakage while driving, then there are some things that you can do:

  • Park your car on the side of the road.
  • Arrange water to pour on the engine to keep it cool.
  • Call a towing company to haul your truck to the nearest dealership.

You should not drive the truck any further, and the water will help cool things down because high temperatures have never been good for anybody.
