I'm trying to locate the thermostat on my 2000 jeep grand cherokee

Passenger side, front of engine, where the lower hose comes out of the engine, its behind the black plastic thermostat housing that is bolted to the aluminum front timing chain cover. Two bolts hold it on, 8mm socket gets them off.

Locate the top radiator hose...follow it down to the motor...the housing that the hose connects to is where the thermostat is..usually there are 2 screws to remove and then it just comes up and the thermostat is inside

2000 Grand Cherokee allso called WJ, go to 1999-2004 Jeeps; check here for the Fuse Location and Description.

Hope helps (remember rated this). TY for using Fixya.

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 follow the top radiator hose to the engine you will find the thermostat...there shuld be a clamp holding the hose on the housing and there are two bolts that hold the thermostat housing on. once you pull the two bolts you will see the thermostat

follow top radiator hose from radiator to engine wear hose ends, it will be clamped to whats called the gooseneck, thermostat is under that. you will have to drain coolant, not all, maybe 1 half gal. before you remove it. 2 bolts new gasget new thermostat, just remember spring on new thermostat goes in engine.

When the engine is at operating temp check the electric cooling fan. If it is not moving then i would check the fan relay which is located under the right side headlamp. 9 times out of 10 this is the problem
