01 start up sounds like dying baby seal

Almost everytime I start my XJ I get terrible screeching from the engine compartment, if i turn off the AC and turn it back on it sometimes stops. Is anybody else having this problem and have you figured out what the problem is?

Damn posted just as you were! LOL

Nope
Need a 15 mm wrench and a 15 mm socket. adjustment is on the idler wheel just below the power steering pump.
Loosen the bolt holding the wheel. then tighten the 15 mm bolt head facing up just below the temp sensor on the thermostat housing. There is a tool u can get to check the tension of the belt. It should be at 125 PSI on that tool. I don;t have it so I just tighten until I can pluck the belt like a string.
Now re-tighten the bolt holding the wheel.

So would it be a good idea for me to just get a new belt?

And I was going to suggest changing the dying baby Seal for a more healthy one...

Oftentimes, a new belt needs to be "retightened" once after it has been run for a few miles. They can stretch just a tad and that can leave you with "baby seal" noise. I have had to retighten the belts I have installed on my 99 every single time.

But even with 7k on it, you still need to perform a close inspection for "glazing" (shiny spots) and if it is glazed, replace it. I prefer the Goodyear Gatorback for the replacement belt on the 4.0 engine.

Without "data", all you have is an opinion!

you should be fine with the belt you got, you just need to tighten it up like the others said. very easy to do. obviously do it with engine off.

if your standing in front of the jeep with the hood open, below the power steering pump there is a belt pulley with a 15mm bolt, sort of hard to reach but get a wrench on there and turn it left towards the passenger side . Watch your hand on the metal fan when you do this. once this bolt is loosened you can begin to adjust your belt.

There is another 15mm bolt sort of behind the power steering pump, near the valve cover. its on a slant. a ratchet with an extension and 15mm works great or you can use a wrench again, it will just be slower. You want to turn this bolt clockwise to tighten the belt. so if your wrench is on the bolt, you want to turn it towards the front of the jeep. tighten the bolt a few turns and then tighten the pulley down below.

start the jeep up and give it a quick rev with the a/c on. if the squeal is still there, repeat the above until its no longer squealing.

it should take maybe 10 minutes to do
