Question about 2000 Jeep Grand Cherokee
Hi David, How long did you run the engine before checking the temperature? The thermostat will only begin to open when the engine has warmed and the gauge begins to move. If after giving it a correct warming period it has still remained cold, I suggest the following. As you have already replaced the water pump, thermostat and radiator cap, the radiator may be blocked. Carry out a back flush, meaning, use a good quality radiator flushing chemical and follow the instructions carefully. Run the engine in accordance with the instructions. Let the engine cool and then draining, flushing the system by connecting a hose pipe with a fairly good head of pressure against the usual direction of flow. If that fails you may need to replace the radiator. Let me know how you get on, Happy new year Regards John

Check water pump and make sure that its working. Should be circulating antifreeze in radiator and in engine. You can also check and the head gasket and make sure its NOT blown. Good luck and thanks for using FIX YA

waterpump houseing/shaft seal is on the way out hence the water/coolant, running along the block. when hot the seal does so, when cold and depressurising seal doesnt.

SOURCE: Overheating Jeep!!
did u properly bleed the air out of the cooling system? if u are not sure raise the front of the jeep as high as u can with a floor jack, fill the coolant recovery bottle all the way up with 50/50 coolant mix and run the engine until it gets hot, then shut it down and run cold water over the radiator core, this will cause the air to bleed out and the coolant in the recovery tank to be sucked in, watch the level in the recovery while u do this, don't let it run dry. If this doesn't cure the problem you have other problems like a poss blown head gasket.

This hose you refer to is the breather tube for the differential. It connects to a fitting at the top of the differential housing and runs up the back side of the radiator so you won't run the risk of water entering the differential if you submerge the front axle in water. Reconnect the rubber hose to the fitting on the differentail.
