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.

Lucas was very friendly and courteous. He arrived on time and replaced the water pump and the thermostat on my car with great care and attention to detail. He did an outstanding job and took the time to explain everything I needed to know. I'm very pleased with his performance and will definitely be using his services in the future as well as recommending "yourmechanic.com" to my family and friends.

He seems professional. I paid for the lights to be addressed and they are all still on including a low engine oil light. He said he would return to check it out further after his next appointment but I did not hear back from him. I was told by BMW that the power steering fluid needs to be drained, flushed and refilled. He sucked it out with a hose twice and this will not ensure that the oil that was accidentally placed in there would be completely removed. I am no mechanic but I am going off of what BMW told me. I wanted to get a lot more work done. I want all the lights to be addressed and fixed so I started with the check engine lights to be looked at and not just reset. I want everything to be fixed. Thank you
