My 1998 Jeep Grand Cherokee is over heating and I have already replaced the water pump. Someone told me it might be the heat censor. Could this be right and if so how much is it going to cost me.

Be careful, with engine at normal oper. temp. feel both upper and lower radiator hoses, they should both feel the same, warm to hot, if not the same temp. replace the thermostat.Heat sensor either work's or not, if it reads hot, engine is hot, or will not work at all.

I think you may be on the right track. If the timing is too far advanced, the engine can overheat. The computer uses the crank sensor input to time the engine. Let us know if it still over heats with the new crank sensor in.

My Jeep is overheaeting, I have replaced the

Try replacing the overflow tank cap, the cap can be pressured checked. If it can't hold the pressure, it will cause the car to overheat slightly or majorly. This is something that a lot of shops and people overlook. Is the belt tight, if not it won't turn the water pump pulley to keep water flowing correctly. Do you see water leaking from any area? Usually if the pump is bad or going out it has a (weep) hole that water will leak from.

Are you losing coolant. If you are I would check your heater core which is located under the glove compartment.

First I need to ask you,when you add 1/2 gallon each weekend,are you putting it in the radiator or reserve container.
Second,when you say it over heats and the reserve tank is always full,Is it clear full and coming out the fill lid.
heater cores can only block water going in to them,it could never cause an over heating problem.
you need to verify the basic system is working properly first.when it is running hot or you hear something different in the engine,what does your temp on the dash say,is it verifying over heating,or not.
the ECT switch is the eyes and ears for the computer,it tells the computer the engine is getting hot and then the computer turns on the radiator fans to cool it down.if the switch is lying or giving false info to the computer,it will never turn the fans on.if you take it to a shop they can test the whole system with a hand held computer and test each part of the system.

From the last portion about your drving conditions, it is normal gets hot, especially going up hills with the A/C on. Sometime the water pumps start to weaken but also a clogged radiator, slowing the flow of cooled coolant through your motor or even through the radiator....check to be sure you have the proper level of coolant also.

With the water pump removed, you have to heat the body of the water pump. There is a O-Ring that seizes the tube into the water pump. Sometimes you can just loosen the bolt and heat the pump with it still bolted up the engine. Use some pliers to wiggle the tube while pulling the tube. When you put it back together replace the o-ring and add some rtv sealant around the o-ring too. This helps the seizing problem. Hope this helps
