How to replace engine belt jeep

This is also valid on any jeep from 1996-2004 with the 4.0 Inline 6. Can also be used for earlier jeeps too! Feel free to ask me any questions!

I have a 1998 jeep cherokee sport that has went through 3 belts in 2 weeks I am thinking it night be the tentioner pully but it isn't a clean break in is it is riping strands at a time off

@davidhowington One of your pulleys is out of alignment

Your Jeep is very clean! Never go offroading?

@Sykora171 occasionally, but its washed and waxed frequently and kept covered

I have a 2002 Jeep Wrangler and after a few minutes on the freeway, I get a high pitch noise that only goes away when I accelerate. If I let the engine idle after the noise starts, it is a constant whine. I am assuming its a bad pulley so Im replacing the idler pulley and the belt. I hope thats all it is. Thanks for the vid.

@fltopp1 Hope it helps. But here is my advice. Its not your belt. Its most likely the idler pulley, but in some rare cases such as mine, it was the water pump. Other cases, its something inside the engine. Take the belt off first, start the car and run it for 5 seconds, if it doesnt make the noise, then its one of the two. While the belt is off, twist each one and check for noises, resistance, or play in the pulley. Then youll have your answer

@fltopp1 yea i dont think its the belt, its probably your pulley my 2000 jeep wrangler was making the same noise...but when i would accelerate the high pitch would get louder =( so yea

@chaosimproved I love that haynes manual. Its my bible. lol. I didnt use it to do the belt though. It wasnt really necessary. Belts are easy

[chaosimproved]

Thanks for posting this video.  Came in handy for replacing mine. I can't tell you how annoying that Haynes manual was getting.
