ZJ Belt Squeak

[NeilSmith]

a water pump can be the culprit when you hear a noise like that. they typically make a grinding noise cause the bearings are wearing out. the water pump of course will make it run hot and could affect your heat. the idler and tensioner pulleys are an easy and cheap fix, probably the cheapest place to start. the ones for the V6 Commander were $16 each from Advance. I would start here since you already did the belt. The ac compressor usually doesnt make a lot of noise , they just lock up. are you losing any antifreeze ? The water pump should have a weep hole where you would see some oily/antifreeze seepage.

I will check the the hole for seepage and antifreeze. (I also know it needs oil, but this wont cause the squeak). Yes I can tell the squeak is coming SPECIFICALLY from where those arrows are pointing. No where else. This squeak is different than from the summer. So what if it is the bearings for the AC Compressor going out. Can those be replaced easily?

Using what? Your calibrated ear drums?

OR one of these?




If I were you, i'd pick up one of those stethoscopes and probe around to pinpoint the actual origin of the squeak. The thing about metal and mechanical systems is that noises are transferred through components very quickly and they'll often resonate the most at a location further away then expected, causing you to look in the wrong spot for the root cause.

^^^^LMAO

lol i wasn't being facetious

Customers don't like when you start throwing parts at a vehicle to eliminate the squeak they're complaining about. Those stethoscopes are a "must have" for this type of troubleshooting IMO

Ive used an extension from a socket set , place it against the ear, not as good as a stethascope though
