okay guys i got an issue that i cant figure out, maybe yall can help, so i was driving last friday, and blew the serpentine belt, here my water pump went so i replaced that stuff then the temperature sensor, still over heating, replaced the fan clutch and still over heating, replaced the thermostat and still over heating... flushed out the whole system and still runs at like 215, it always ran at 180 before this happened, when i realized my belt took a **** my coolant was boiling...? obviously from over heating. but does anyone know what this could be?

 

A clogged radiator or a blown head gasket.

 

i flushed the radiator and just started to run it again, it gets hot but runs at about 210-215.. if the head gasket was blow wouldnt i have mixing oil and coolant? cause there both the colors there supposed to be and one dosnt have more in it then they should..

 

Check the actual temp with a thermometer, or put your old temp sensor back and see if the reading drops back to normal. Your old sensor may have read a bit low, the new one a bit high....they aren't all that accurate.

 

210 is a perfectly normal operating temp for a 4.0.

 

X2.

Does your electric fan come on?

 

yes my electric fan kicks on at about 200, but my jeep always ran around 180 before i blew this belt, i drive about 25 mins everyday to and from work and it seems to stay at 210 but im afraid to take it for a long drive cause of the high temp..

 

Just a FYI. I understand about your temp before. Not sure why is was too low. However 210-218 is a normal SAFe temperature to drive at. And since the electric fan works and passes air over engine dropping temp too 205-210 then you're golden.
