How often should you replace the water pump?

qtrmile is on a distinguished road
The all-important water pump, shoots coolant through the your car's cooling system. It's driven by a belt and operates only when the engine is running. Water pumps fail with some regularity--you can expect to replace yours sometime before 100,000 miles, if not sooner.

step1
Turn the engine off and open the hood.

Step2
Locate the water pump pulley. The pulley is the round part that the belt is attached to. To find it, look for the belts. You will see more than one pulley. Your car will have an alternator with a pulley and perhaps an air conditioner, power steering and smog pump pulleys. If you are unsure, ask your mechanic to point out the water pump pulley.

Step3
Grab opposite ends of the round pulley and check for "play" (looseness): Try to rock it back and forth. There should be no give. If there is, the bearings are going and it's time to replace the water pump. By the time you can feel play in the water pump pulley, you may also be able to hear the bad bearing when the engine is running - there may be a low-pitched grinding noise coming from the water pump pulley.

Step4
Visually check the water pump (it's located behind the pulley) for signs of a coolant leak. If the water pump gasket is leaking, it must be replaced. This is a good time to get a new water pump, too, unless it was just recently replaced.

Wow, thanks for the totally worthless post. Work on I4's much? The water pump is on the timing belt, kinda hard to do a quick inspection. Instead of cut and paste post something you KNOW ABOUT.

To the OP, ignore this guy and listen to twokexlv6coupe.

Would a worn down water pump (the blades get smaller over time) decrease fuel efficiency due to higher engine temperatures?
