Jeep runs hot
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.

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.
