I got a 1996 jeep Cherokee 3-1/2 inch lift on 33" tires ever since i got it it over heats to red and it shuts off. I've replaced thermostat, radiator, flushed coolant, fan hub. None of this have helped at all some times when I run the A/C keeps it cooler for longer but it will over heat even if I'm driving on the high way doin 65/75MPH. If anyone of u guys out there knows what the problem is I will appreciate your help! Thanks!! I'm about ready to get rid of it cuz I'm tired of it! But at the same time i dont I just wanna fix and keep it!

 

over heats as boils over and water comes out the over flo bottle??

 

New water pump? When u say fan hub, do u mean fan clutch? Air flow thru condenser and rad being block in any way? Both fan shrouds intact?

 

Summer and hotter weather is here, I am looking at mt temp guage rising also and hoped the flushed radiator and thermostat change would help too. Better, but not good enough. If you are In a southern climate and thats the original radiator since 96 you are doing good. I am going to bite the bullit and replace mine, Here in Tampa their life is much shorter, I rolled the dice a few years ago on another truck and put it off. Ended up with a blown head gasket.
I have been spraying my transmission line fittings with "Blaster" every few days while I shop for new one. The job goes a lot smoother if those connections come apart clean. May invest in a seperate transmision cooler also.

 

No never boils over. It just shuts off when it gets too hot

 

I've been thinking about putting in a new water pump. Yea the fan clutch. The condenser looks fine I just put a new rad on it and I mean new not used. The fan shrouds look fine.

 

are you sure its over heating, and its not the sensor that power the gauge is not bad causing the ecm to shut the motor off

 

Well the hood feels really hot more then usual but that could be just me over thinking... also put a new sensor on the the end of the valve cover by the firewall. Should I be replacing the one on the thermostat housing as well? Is there another sensor somewhere that I'm not aware of?? Do you know?

 

the one in the back of the head control the gauge the other in the thermostat housing controls the cooling fan

 

So the one in the back would be the one telling the ECM to shut it off cuz it's too hot right?

 

does it over heat when idleing or driving or both

 

pretty sure that just powers the gauge

 

get a new viscous fan clutch, or a new water pump

 

Both even while driving on the highway doin 65\75MPH

 

I think the new water pump is next...
