I know the is another one posted tonight, but i didn't want to muddy the waters in that thread. I am about to blow this thing up, I am so fed up. this is going to be long!
This is the 3rd summer since a ground up rebuild of this Jeep and I still can not solve the overheating issues. I built this to camp and explore but I am afraid to take it beyond cell service.
When I say EXHAUSTIVE, I mean it.
I have built several XJ's before this one and knew exactly what to do and how to solve all the problems.
This is a 98 with a completely rebuilt drive train. Motor and head were rebuilt, aw4 was rebuilt along with the tcase. Axles are stock JK 30/44 running stock JK tires and 3.73 gears.
Currently running CSF radiator, locked fan clutch, stock efan, hayden trans cooler, FlowKooler pump, 50/50 mix w/redline additive, 180 thermostat, and hood vents. I have no cat and all new exhaust. There are no signs/indications of head gasket leaks. I have burped it every way possible. Performance is what you expect for 33's and 3.73's.
Temps have been checked with a laser gun and 2 different sensors. Read via OBDII and Torque app.
My normal commute (13 miles in SLC) temps run 225-238!! Surface streets or freeway at 70, AC on or off, makes no difference. Will drop to 220ish if left to idle. Under 80 days it is fine and runs about 210. Winter about 190-200.
Plugs look good, running full synthetic, not using any oil, timing and vacum seem correct via obdII.
I have tried every combo of the following parts. Stock HD aluminum rad, stock water pump, new XJ fanclutch, new ZJ fanclutch, 160/180/190 thermostat (the good ones), 2 different new caps, and bypassing the heater core.
I have flushed it so many times that I would drink the water out of it. (waterpump off and pressure washer in the block) I even pulled the CSF radiator and had it checked and flushed at the best shop in the state.
I am seriously about to put a stick of dynamite under this thing!! I am beyond frustrated!!
I would LOVE any ideas you all have. I am very experience and tried everything I can think of. I went to the forums and have read hundreds of posts. I am at the end of my rope!!!!hasta
