You can know the water pump is bad in a Ford F150, when you hear buzzing sounds, or see leaks in it. Then again, you should also experience low fuel efficiency and loss of power afterwards. The coolant doesn’t circulate properly, and the engine heats up faster, causing the problems.

Uncomfortable Noise

Generally, it’s the level of the coolant. Incorrect coolant level can make the engine go belugas and shake. This is when the noise usually kicks in. 

Fluid Leaks

Due to overuse, old F150 water pumps start to leak from the nooks and crannies of the pump. Sometimes, the transmission may stress out the water pump, causing it to leak. 

Engine Overheating

Here, the Engine heats up too often. The optimum temperature for F150 engines to work is 90-degrees celsius max. Afterwards, you will experience thermal throttling. The water pump either doesn’t have enough coolant level or the pump is broken. 

Loss Of Power

When the engine heats up above 90-degree Celcius, the max power output is decreased. You will be left with a loss of power and a headache on what is happening. Try increasing the fluid level, and fix any leaks you find. This should do the trick. 

Loss Of Fuel Efficiency

If the coolant isn’t circulating properly, then the engine gets into thermal throttle mode. As a result the engine loses its fuel efficiency for everytime it warms up and cools down. This is kinda like a protection feature so that the heat doesn’t toast the engine inside out. 

Loose Water Pump Bolts

Sometimes, the bolt may get loose. Your mechanic may not tighten the bolts properly, or the transmission vibration knocked it loose. Anyhow, you need to tighten it properly. 

Loose Belt

If your F150’s belt is too old, you need to replace it. With time, the belt starts to loosen and it’s one of the most common problems. Cracks or fraying may also cause the belt to loosen up and malfunction. 

Transmission Problem

Fluid leaks from the water pump is to blame here. A broken seal in the pump will allow the coolant to leak out, and the transmission system will go nuts. However, you may have other leaks in the transmission system, which causes this problem. You need to seal them all.

Pro-Tip: Sometimes, the problem isn’t in the water pump. You need to check the Ford F150 6-Speed Transmission to resolve any transmission problem.

  • Next, remove the bolt that secures the water pump housing to the engine block. Use a socket wrench for this. 
  • Examine the water pump impeller for cracks or chips. In rare cases, you need to replace the impeller.
