ZJ Belt Squeak

[AJeepZJ]

I've included a picture. My belt has begun squeaking ever since it started getting cold. Just an FYI, the 96 V8 has a self-adjusting tensioner to the belt. The belt is not coming off track, it's not damaged (it's a brand new belt I put in), I've applied conditioner to the belt - and this worked untill it started getting cold.

The tensioner is not the cause of the squeak. I've included arrows on the picture as to what I think IS causing the squeak. Taps, squeaks, and creeks drive me insane - I MUST FIX this. In order to determine what THIS is, I need a little help.

Now that I've had a chance to break this ZJ in - I've found some issues I'd like to try and resolve.

First - What is the pulley that my arrows are pointing to (I think it's the water pump) and what does it control.
Second - Is there anything else that can cause the belt to squeak?
3rd - My heat ONLY works when the thermo is on max heat - What could be causing this and is it related to my squeak
4th - I've heard that if you here a squishing/gushing sound when you start the car and the AC/Heat is on - there is something wrong with the Heater Core - can anyone confirm, and is this a pricey fix - and is this related to my 3rd problem.


Thats all for now.

How do you know it's not the tensioner?

1st Whats hooked up to it? Don't look like your alternator but maybe the compressor. Look and see what kind of lines are hooked to it.
2nd Lots of stuff can cause a squeak bro.
3rd what do you mean max heat using the temperature blend?
4th If you hear gushing or gurgling sounds it's probably air in the system that would be my guess.

1st - I don't have a pic available to show me whats hooked up to it. I'll get it first thing in the morning
2nd - Lets list those things, lol.
3rd - Heat only comes out when you turn the heat all the way up, not the fan. The temperature.
4th - Is this normal or is there a way to purge this air out.

It's definitely not the alternator, thats to the left. The arrows I think are pointing either to the Air Compressor or the Water Pump. Confirm?

[Sal-XK]

That would be weird water pump so I'll go with compressor.

Is your blend door operated by a cable it may need adjustment I'm not sure when they stopped using cables on those.

Everything that the belt drives can cause a squeak bro so that's a long list to include all the pulleys.

alternator on the left, your arrow points to AC compressor, water pump is down there below in the middle ( I think, hard to see ) power steering pump bottom right. I replaced the tensioner pulley and the idler pulley yesterday, one of them was starting to make a grinding - bearing sound on start up in the cold. Fix it right up.

Still think its the waterpump.....

Sounds like the bearings on the Compressor.

It is. Well Kinda.. All the problems I have are Heat/AC related. Heat only working when it's turned up all the way, A squeak that goes away after 10 minutes but returns when you turn on the Heat or AC. I've actually decided to sell it, but not because of these issues. I'm going to fix it, and sell it. I can't keep track of two vehicles in college. Especially when I head off to Army next year. I've become a little blind to some of the things that the WK needs. ZJ will be gone within the next month. I can start pumping money into my WK. If everything goes as planned... I'll have another grand sometime late next year.

yup... that sucks

May i suggest: Dorman 34178. $30

Got a link? What it will cost to fix actually ain't that bad at all. I can also replace the bearings, pulley and some other component for about 110, but you suggestion sure beats the hell out of that.

just Google the part number.. its an AC delete kit.

When you replace the bearings and stuff don't forget the a/c recharge. Its gonna be more than $100 for everything. BUT, if you want AC that's what you have to do...

[jcoulter]

Did you replace the bearing? How bad is it to pull?
