Take the belt off check the clutch fan and spin all the pullies insure they spin freely and do not wobble if any do replace them if all checks out ok put a new belt on. make sure the belt tension is not to tight should have about 3/4 inch play.

Screeching noise from somewhere in belt pattern. Not idler, tensioner, power steering or belt. Does not run hot as if it were the water pump. It does get louder as the RPM's rise. I think it's the be


It doesnt have to be over heating if the water pump bearings are bad. I take wd-40 and spray one pulley at a time on the back side if possible to isolate the bad pully bearings. Start with your ac compressor first because next to the idler the ac pulley sqeals alot.

I have a 1998 jeep cherokee classic with 4 litre 6 it just developed a coolant leak in the front center of the engine pulley for water pump has a little play in it and i cant tell if its the water pump...


It sounds like your water pump is going out. Water pumps have a weep hole on them and when the seal is going out it will start leaking. Also you shouldn't have any play on the pulley.

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.

1995 Jeep Grand Cherokee squeaking and power steering


It very well could be the pawer steering pump. But to isolate the squeking sound, take that can of wd-40 and find the idler pully and tensior pully. Spray the bearing area of both pulleys. If your bearing in those pulleys are going bad then it will make that noise. If the wd-40 quits the noise at one of those tow pulleys then you know which one to replace. If its does not, then start looking to replace the powersteering pump. I take it you have checked the power steering fluid levels and they are ok?? Also, you stated that the noise started after you bought the alternator, then try a new alternator. It might of just been a faulty alternator. Happens all the time. One last inexpensive tip is replacing all belts with new. Belts get glazed over and dirty and cause noise too. One last question. Did you make sure the belts were tight enough? Just a little variance in the belt tension can make the difference.

Timing belt and pulley


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.

91 Jeep Cherokee Loredo/serpintine belt travels and shreds inside part of belt! Has new water pump and idle pulley(had a new belt!).


Possibly who ever replaced the water pump did not line up one of the pulleys or an idler correctly. If it is not spaced correctly the serpentine belt will not follow the grooves in the pulley. This will cause the belt to jump out of the grooves and jump track and rub on the pulley and shred it within a few minutes or seconds depending on how badly it is misaligned.Check the alignment on the pulleys and the routing path of the belt. Both must be correct in order to work properly.
