Squeal at 2k RPM.

aI get a whine from the engine at 2k rpm when it is under load. Almost sounds like a fan belt squeal.

I just replaced the water pump 500 miles ago, it was shot, it would make the noise before the pump change.

I can't recreate the noise in my garage. Any suggestions?

Thank you!

-Josh

Hi Josh I remove the drive belt and replace it with a rubber belt that i can tie off to a miss out a component to test, this allows me to test individual components by eliminating them from the drive belt.

It may be the alternator bearings, remove the drive belt and turn the pulley by hand to feel for play or roughness.

hope this helps

What are you using for your rubber belt?

Hi Josh a piece of the ribbed rubber mat from the floor of my tub cut into a strip with holes punched into it so i can adjust the length.

You can also isolate a squeaky belt with soap and water. Spray it on the suspect belt, and it should go quiet for a short time until the water evaporates. Just don't use any of the "belt quiet" sprays on there. It really does a number on the belt, doesn't last long, and you need to clean it off all the pulleys when you finally do change the belt.

Could also be the alternator bearing, or the tensioner bearing.
