I have a 93 Jeep Grand Cherokee inline 6 4.0L and it keeps overheating I have replaced the thermostat, top hose, water pump, bottom radiator hose, and the fan. I need help it is still getting very warm when I stop at lights or anything else that requires sitting with it on. Thanks.

 

How hot is it getting?The reason i ask the 4.0 runs hotter then most engines,The thermostat don't open tell like 195 and then its just getting to a happy temp.

 

It is almost red lining.

 

its an old vehicle, how is the condition of the radiator? that is the only component that you have not replaced yet.

 

what fan or what part of the fan did you replace? e-fan? fan clutch? if not already done I'd replace the clutch.

does your e-fan kicks on when your gauge rises past 215? if not change your temp sensor in the thermostat housing.

if those things don't help, and based on what you already replaced, then i'd look into a new radiator.

 

Hi guys, i think that radiator is clogged, cheers!

 

What degrees is it running at ?Or take a infrared temperature gun and check the temp of the upper radiator hose.
