Jeep Grand Cherokee making a squealing noise

My Jeep is making a squealing noise. I don't think it's the water pump but wondering if it could be the serpentine belt or a pully that needs replace

SOURCE: HOW DO I CHANGE THE WATER PUMP ON A 99 JEEP GRAND CHEROKEE ?

At least you have the 4 liter 6. Once you get all the **** out of the way its like replacing a W/P on an "old school" engine, very much like a Ford or Chevy straight 6. 1) Remove radiator top retainer (the metal U that looks like its the top of the radiator (#13 or 14mm sockets I think). 2) To completely get if off you also have to remove the grill (4-6 phillips screws), then 3) unbolt it from the tubular bumper retainers underneath the grill. 4) DO NOT remove the latch cable - no need. 5) Remove the top bolts holding down the fan shroud. Lift the shroud off its bottom "tabs" and push over the fan. 6) Using #10mm socket remove fan from fan clutch, then remove bolts holding fan clutch onto water pump pulley. 7) Pull out shroud, then fan, then fan clutch. Be very patient, lots of wiggling may be needed. 8) Locate belt tensioner on idler puller below the Power steering pump. Losen very little the pulleys center bolt (10mm), then use a 10mm w/entension to losen the pulley's tension (use counter clockwise/normal rotation to losen). 9) Draw a diagram of the belt routing - you will Never remember it correctly otherwise. 10) Tap the w/p pully and pull if off - do not hit radiator fins! 11) Drain the radiator (clockwise/right rotation opens petoc from factory radiators - counterclock used on aftermaket rads). 12) Remove lower raditor hose at radiator, then at pump (it will be a challenge). 13) Remove upper radiator hose from rad and from thermostat housing. 14) losen the Rubber heater hose from the metal hose screwed into the W/P. 15) Remove 4 bolts from W/P (13 or 14mm I think). The one at the 4oclock position is longer than the others. One is hidden at 6oclock.
16) Remove 2 bolts (14-15mm??) on bottom of Power Steering mount - these go through the W/P case to the block. You may also need to losen the top PS bolts so the PS Bracket can be loose at the W/P case. 17) Wiggle the W/P out from under the PS bracket. and pull off. (16b if needed, remove the upper idler pulley near the A/C unit.) 18) Remove the Thermostat (upper hose return) housing. Scrape off old gasket. Replace with 160deg or 190deg thermostat. Use silicone on gasket. 19) Carefully use a 17 or 19mm box wrench to remove the metal heater hose return line from the upper part of the old water pump. Coat threads with spark plug thread antiseize and screw onto new W/P. 20) Install new W/P gasket w/silcone, be careful to Not block the water holes. 21) Slide W/P under the P/S bracket and jiggle into place. Hand thread one of the top bolts to hold the W/P in place. 22) Insert the P/S bracket bolts and lightly tighten. 23) Jiggle W/P around and insert other bolts, start with the 6oc hidden bolt. Add remaining bolts and tighten to 25 or 250?ftlb (about 3/4 past socket-snug). 24) Tighten ALL P/S bolts. 25) Adjust metal heater pipe. Reinstall rubber heater hose. 26) Reinstall W/P pulley and Fan clutch, and upper idler if it was removed. 27) Thread NEW Belt on pulleys. 28) Tighten tension on idler. Tighten idler axle bolt. 29) Install lower rad hose. 30) Slide shroud over pulleys. 31) Install fan on clutch. 32) Clip shroud retainer bolt mounts back on top of radiator. 33) Install shroud. 34) Connect upper hose. 35) Reinstall radiator retainer. 36) Bolt retainer to Tubular bumper mounts. 37) Reinstall grill. 38) Wonder where the extra bolts etc are supposed to go. 39) Cuss - pray -cuss - pray. 40 ) sip some beer. 41) carefully inspect everything to ensure its back to the way it looked before (several pictures from a digital camera taken during the disassembly will help). 42) Close the rad petok. 43) Add 1 gallons of antifreeze. 44) Start engine and add another gallon of A/F. 45) Turn heater controls to HOT inside (no need for fan). 46) Water guage should show 180 to 210F. 47) Add 1 gallon of water. 48) Install New 18PSI rad cap. 49) Turn off engine and add water or A/F to overflow tank. 50) 1 hour later open Cap to see if level has settled. Add Water as needed to fill rad.

SOURCE: Loud squealing sound in my engine

Try removing the belt and turning each pulley by hand. If everything is smooth and free, with the belt still off, drive down the block once and see if the noise is there (this will eliminate all rotating accessories on the front). If you hear the noise, then there is a problem deeper inside. Oil pressure is good? Dont' forget when doing this, you will have no power steering, so be careful.

Faceing the Engine The Tentioner is on the LEFT side next Pulley Down from the Alternator , Use A Box end 6 point Wrench to Turn Tentioner To the Right (CLOCKWISE) to Loosen the Belt, Take A Good Look at it If there is No Belt Diagram to Remember the Way It is Routed if thats all you need then you R on your way. Good luck !

I have a 1996 jeep grand Cherokee. It runs fine except for the squealing belt! Just replaced the water pump and the belt and it's now worse than it was before! Any ideas? I checked the auto tensioner...


You have an out of alignment belt run across the pulleys of the engine, this causes the belt to make noise as it rubs on the edge. Many times this is causes by the crankshaft vibration damper coming part and the pulley walking outward.

Squeal while accellerating in 1995 jeep grand cherokee


The idler pulleys on the Cherokees are known to squeal and make noises when their bearings are bad. They are also known to eventually break off and disable the vehicle, if not replaced when they're bad.

I have a 2003 Jeep Grand Cherokee. When I turn my steering wheel to the left it makes a air compressed noise. What could this be? It only does it when it turns left.


You don't say how far you are turning the wheel. If you are turning it all the way, you will hear the power steering pump bypassing. It does that so it won't blow hoses. If you hear it at a slight turn, You may have air in the line and needs to be bled. That should only happen when the pump is replaced.

My 1998 jeep grand cherokee is running hot and leaking water, is the water pump bad?


well first i would check all the water hoses in the engine compartment for cracks and leaks then check around the radiater for leaks if you don't see any water leaking from the hoses or the radiater then try to see if you see water coming from the water pump behind the cooling fan if the water is leaking from behind the cooling fan then it is most likely your water pump

2005 grand cherokee squealing and loss of coolant


Check belt tension, squeeling is most likely due to belt slippage. Have you noticed any fluid leaking from under your Jeep? Coolant level drop could be from bad water pump, when the pump needs replacing, water flows out of a "weep hole". It could be leaking onto your belt also, causing it to squeel

My jeep grand cherokee started overheating at idle


try the water pump - first - make sure the radiator is really full - take the cap off cold and fill - if it looks full - start and run 8 minutes or so - then fill it up - look at ur fan belt - is it tight - tight is about how much pressure u use to make a firm hand shake with little movement - any movement over about an inch is loose - when the jeep warms up the belt can slip and not even make a noise - - new materials don't always squeal. - then be sure ur water pump is ok - they go slowing - the fins wear down - one more thing is the radiator - u don't say how many miles or what maintenance schedules you have or not so that's it for now
