Question about 1999 Jeep Grand Cherokee

1 Answer

I have a 1999 Jeep Grand Cherokee Limited with a 4.7 liter engine and a leaking radiator I'm trying to replace. The cooling fan clutch assembly is supposed to come out together with the fan shroud because the shroud alone will not clear the fan blades and clutch. How does the clutch assembly come off? I have the 36 mm wrench for the nut behind the fan but there is nothing to hold the fan belt pulley so I can wrench against the nut. They turn together. Is there a special tool needed? Then I would like to know how the radiator comes out. On the left side it seems to be held in by very close a/c tubes. I got the two top bolts out that hold the radiator in place but the condenser moves with it and those tubes are in the way. I'd appreciate your help a lot. Thanks

    You really don't need to remove the fan. just push the shroud back out of the way and leave it there. The top support over the radiator should be removed entirely so you can lift the radiator up.

    Yup, I tried that but the electric cooling fan bolted to the inside of the shroud keeps me from pushing it back far enough.

    Electric fan is bolted...not welded...unbolt it.

My info showed a spanner wrench to hold it. I can't see anything from here, I don't know if you could rig up something else to hold it? In the past, I have used a pipe wrench to hold a pulley, If no other way, or a pair of vice grips? You have to be careful not to damage anything.

SOURCE: 1999 Jeep Grand Cherokee : Replaced Water Pump and Drive Belt now Jeep won't start?

When you replaced the Water Pump, did you replace the Timing Belt? Any time you replace a Water Pump you have to replace the timing belt because it stretches out. If you did not then most likely your Engine is out of time and there for will not start, but it will turn over. hope this helps, good luck.

I don't know of any real proceedure, Just make sure its full and there is no air traped in the system, If there are any bleeders like around the thermostat housing, or any where in the cooling system open them up while you fill it to let any air to excape If not just fill radiator untill your sure you can't get any more in it before you start it.

If you have the same pulley arrangement that most 4.0 engines have that pulley is an idler not a tensioner. Your power steering pump has a pivot bolt, and a slide under the pump. You adjust belt tension using the pump.

I have a 98 jeep grand Cherokee limited ONLY when i run the a/c it overheats replaced the water pump,thermostat,upper and lower hose,there no leaks anywhere only has a mechanical fan how do I fix


By any chance, does the electric cooling fan shut off when you turn the AC on? If so, either the wiring to the fan assembly has been compromised, or the cooling fan relay is bad.

Typically you need to replace the fan clutch. (This is presuming that you are not overheating and not near too hot. Under hot condition, your issue is normal.) The clutch can fail in the locked position.

Jeep Grand Cherokee running hot. I've changed the


Check your radiator for external and internal obstructions (leaves, bugs etc on the a/c condenser or leaves between the condenser and radiator, rust or calcium deposits inside the radiator core all cause loss of heat transfer)
Also make sure that the system is full and that the electric fan and the clutch fan are operating properly. (electric fan should come on just above normal operating temp and clutch fan should not be "freewheeling" above temp either)
Note: If you need to have the radiator flushed, do it separately from the engine. especially the inline 6 and 4 engines rust up inside and if the system is flushed with the radiator connected, the debris will pack up inside it and actually can worsen the condition.

How do i change a water pump on 1996 grand cherokee limited V8


I'll assume you have a 4.0l

The 4.0L engine is equipped with a reverse rotation (counterclockwise) water pump. The word REVERSE is stamped or imprinted on the cover of the viscous fan drive and on the inner side of t he fan. The letter R is stamped onto the water pump impeller. When replacing water pump, ensure proper pump is installed. Installation of the wrong water pump will cause engine overheating.

NOTE:On models with 4.0 L engine, front grill must be removed to access radiator draincock. Draining cooling system can be accomplished by removing drain plug from side of block as well as by loosening radiator draincock. Drain plug is located on lower left side of engine block.

Disconnect negative battery cable. Drain cooling system. Disconnect electric cooling fan connector. Remove electric cooling fan and electric fan shroud assembly (if equipped).
Loosen, but do not remove, 4 water pump pulley-to-water pump hub bolts and 4 viscous fan-to-idler pulley nuts. Remove accessory drive belt. Remove 4 viscous fan to idler pulley nuts, and remove fan and shroud together.
Remove 4 water pump pulley bolts and remove pulley. Remove power steering pump and bracket. Disconnect heater hoses and lower radiator hose at water pump. Remove 4 water pump retaining bolts. Remove water pump.

I have a 1994 Jeep Grand Cherokee Limited, 5.2 liter engine. There is transmission fluid leaking out from around the radiator. Were are the transmission lines leading to and from the radiator located?


Check both connections to make sure they are tight. Look carefully to see if fluid is coming from the fitting or where the nipple comes out of the radiator...If leaking there it usually can be fixed by any decent radiator shop.
