1.Your engine has an internal timing chain, not a belt.
Therefore I'm going to assume that you mean the serpentine drive belt.
Common causes for belt to fail is either a mis-aligned or damaged pulley, improper belt tension, or bad tensioner spring (if equipped with spring loaded tensioner) You mentioned a loose pulley but didn't say which one! That's what I'd look at first! Also, make sure that all pulleys have no "wobble" indicating a bad pulley bearing Most common: water pump or idler pulley.

1996 jeep cherokee sport with 4.0 does not have a tensioner on the fan belt. How do you change it?


One of the idler pulleys has a built in spring loaded tensioner. You have to use a ratchet to turn it, which relieves tension on the belt while removing and also when replacing the belt.

Hello, how to relieve the belt tension on jeep grand cherokee 1995?


Hi,


In order to relieve the belt tension in your cherokee jeep,you have to locate the belt tensioner pulley first, which is found between the crankshaft and a component toward the top of the hood area.

Afterwards,Rotate the belt tensioner pulley, using a wrench spanner to relieve the tension on the belt.



Good luck.

the power steering pump has a seperate adjuster bolt ont the bottom left of the pump if you loosen this off then loosen the pulley bolt it iwill move in to allow for the belt then tighten the adjuster bolt till the tension on the belt only allows for a 1/2 inch movement up or down then tighten pulley bolt

I need the drive belt configuration for a 1988 Jeep Cherokee.


To replace belt, first loosen the pivot and slide bolt on the steering pump, then use the jack bolt below the pump to move it. Belt goes (ccw) around outside of ps pump, under idler pulley, over a/c compressorover alternator over fan pulley, over crank pulley over water pump and back to the ps pump. best bottom (grooved area) should match with any pulley with grooves, back of belt should contact smooth pulleys. 9example...grooved part contacts ps pulley, smooth back goes under idler pulley) When finished the water pump should spin ccw (I've seen them put on incorrectly so it turns backwards) Tighten jack bolt till the long strech of belt is giving about 1" deflection, then lock pivot and slide bolts down.

Drive belt came off pulley loose on 2007 jeep grand laredo


The center pully is the IDLER PULLEY.
It is also referred to as the TENSIONER.

It has a coiled spring that creates the belt tension. Replace it ($15) (and the belt) ($8).

Hope this helps!

Jeep cherokee country tensioner pulley noise


May be a weak tensioner that needs replacing. Make sure you clean pulleys well with brake cleaner or similar as well. I have had one with similar problem, that Gator back belt was causing it. I'm not 100% convinced that a notched belt will get as good a grip as a complete rib all the way around the belt. Just doesn't add up to me. If you compare that to tire grip, then you'd be telling me that snow tires would work better on the Nascar circuit?

Serpentine belt wont stop slipping


sounds like your belt tensioner pulley may be defective, also check all the pulleys for excessive play in the pulley bearings, these are the most common causes.

Replacing fan belt


1.Most modern cars have an IDLER pulley in the fan belt train of pulleys with a heavy spring on it that keeps tension on the timing belt.

2. Get a spanner/socket and put it on the nut in the middle of the idler pulley.

3.heave on the spannner and the pulley will swing up/down out of the way realeasing tension on the belt. (depending on the tensioner setup)

4. Simply remove old belt and thread new belt on. Simple.
