I have a 1988 jeep Cherokee she started running hot so I replaced these items water pump,fan clutch wired the e-fan to run all the time,replaced the radiator, the thermostat and housing,and the coolant reservoir ,we just did a compression test on it and 2 cylinder register 145,2 register @ 140 and 2 @ 120 wtf is my head gasket blown? Any ideas why she could be running hot still.....

 

Fan shrouds intact/in place, condenser clear of mud/bugs etc., no obstruction for good air thru the grille? R the 2 low cylinders next to each other?

 

IV been having the same issues, everything IV got has been replaced and I'm still running warm.

Are you loosing coolant or oil?
Is your coolant a murkey color?
Do you still have the old style cooling system with pressurized bubble on passenger side?
If so you may have a large air pocket in the radiator causeing your problems.

 

no shrouds and no obstructions in the grill I'm gonna try the air pocket theory but I don't think that's It and it stays hot even on the road unless I run the heater

 

No the cylinders that are at 120 are the 1st and last cylinders

 

Fan shrouds direct max air flow thru the rad....might consider replacing them. Might want to do a cylinder leak down test.

 

The caps for the coolant bottle are generally cheap chinese crap. Is that redundant? Get a cap number 703-1396 for your bottle from Napa.

 

I will and post the results sorry for the double post of this thread just need to fix it cuz its my daily driver and my buddy says its time to do a head gasket
