95 satun overheating ihave changed the thermastat bur the cooling fan wont kick in

Here's a link to removing your thermostat.

check thermastat sencer it is loctated on thermastat housing or block

Possibilities include blown fuse due to too much fan current draw, faulty wiring, faulty cooling fan relay, check the cooling fan relay in underhood fuse box. the contacts may be burnt and sticking.

Sounds like your cooling fan relay is bad the jeep grand cherokees are known for this, first thing i would do is unplug the radiator cooling fan and run 2 jumper wires direct from the battery to the fan connector if the fan kicks on your fan motor is good and the relay is bad, if the fan doesnt kick on replace the fan motor with a new unit, the cooling fan relay on your particular model jeep is located under the passenger headlight and requires you remove the front bumper to replace it, however some people cut a small hole under the headlight to access the relay the faster way but if your not to keen on cutting holes in your car remove the bumper and replace the relay if the fan checks out and you wont be overheating anymore...

Alot of time you have to bleed the cooling system after changing a thermostat it gets an air pocket in it look for a bleeder valve near or on the thermastat housing if so bleed it to get the air out.check the radiator and make sure its full because if you filled it up after changing the thermastat once the thermastat opened after the engine ran awhile well the cooling system needs refilled.

YOUR WATER PUMP COULD BE BAD.CHECK TO SEE IF WEEP HOLE LEAKING IS SO REPLACE IT IF NOT.MAKE SURE COOLANT FAN IS WORKING.HAVE RADIATOR SHOP PRESSURIZE COOLANT SYSTEM.TO CHECK FOR LEAKING HEAD GASKET.ALSO HAVE RADIATOR SHOP FLUSH RADIATOR.IF ITS CLOGGED UP.IT WILL CAUSE OVERHEATING PROBLEMS.ALSO MAKE SURE YOUR ENGINE COOLANT MIXTURE 50% WATER 50% ANTIFREEZE.TOO MUCH WATER IN RADIATOR WILL CAUSE OVERHEATING.

first useing a scanner or temp gun check the actual engine temp. if it is hot check for fan opperation, air lock in the cooling system water pump operation I think youll find the prblem to be the fan

Could be the FAN MOTOR, COOLING FAN TURN ON SENSOR, even the PCM. There are 2 fuses . Also check fuse panel under hood in engine compartment

95 in celsius is 202 degrees in fahrenheit. the cooling fans kick on at 190 degrees. 202 is hot but if its been a long time the thermostat been change . change it.wont hurt it.

Make sure your fan is functional. If the fan is not working this can be a problem as it will not cool the engine.
