Water Pump Replacement Service & Cost

What is the Water Pump all about?

The water pump, a container made of aluminum or iron, is part of the cooling system. It contains an impeller (looks like a fan) that circulates water and coolant throughout the cooling system, keeping the engine from overheating. It is located in the engine compartment. For the water pump to work, it needs to turn. This is accomplished either by the drive belt or timing belt/chain. If the water pump is not working, the coolant will not circulate through the cooling system causing the engine to overheat and get severe damages.

Keep in mind:

  • When the water pump is replaced, the drive belts and timing belt/chain may need to be replaced as well.
  • The entire cooling system should be inspected when the water pump is replaced.
  • Replacing the thermostat at the same time as the water pump can help prevent future problems.

How it's done:

  • Pressure test the cooling system for leaks.
  • Remove and replace the water pump if bad.
  • Fill with new coolant.
  • Install new radiator cap.
  • Install new thermostat.
  • Test drive car.

Our recommendation:

If you see coolant (green, red, or yellow fluid) underneath your car, have the cooling system inspected for leaks. Always keep up with the service intervals as specified by the manufacturer and get the coolant replaced. It is a good practice to get the coolant replaced every 50,000 miles. This will help ensure a long life for the water pump and the entire cooling system.

What common symptoms indicate you may need to replace the Water Pump?

  • Coolant (green, red or yellow fluid) is leaking.
  • Car is overheating.
  • Car does not start.

How important is this service?

A car’s engine generates so much heat that it can damage itself if it is not cooled down. To prevent this, your vehicle has a cooling system. The water pump is responsible for circulating coolant through the engine. This coolant absorbs heat from the engine, and is then cooled down by a fan. When the water pump malfunctions, the cooling system has no way of sending coolant into the engine, and the engine will overheat, which can cause severe damage.

This was our first time to utilize Your Mechanic and we were quite pleased. We selected Alex for our needs based on his ratings. Turns out they were spot on and well-deserved. While we ended up spending more than we had hoped to, we feel as though Alex delivered on the work that needed to be done. He was very knowledgeable and we feel confident in using him for future needs and recommending him to others.

Duane

Really disappointed and frustrated! Car never overheated but I knew my water pump was leaking. After making appointment, day of appointment it got canceled due to part not arriving. The next day he came out and 5 hours later it was done (supposedly). I called Duane stating lights on dash (abs, esp and coolant) and was told to drive it and would go away. I drove it, not even 5 minutes and car is overheating called Duane again and met him at gas station near by where he was filling up. Long and behold now he's telling me that cooling fan kicked the bucket ($1700estimate) and there's air in the system. He would take care of it once he comes out to replace the $1700 cooling fan.
