HELP! Age old overheating-I'm lost
Okay so to start I have read through several threads and have done everything I can think of but at this point I'm lost.
So here's what my '96 XJ, 4.0 is doing. When starting it cold it will warm up to about 200*, temp will drop as the T-stat opens to about 185-190, then the temp will just continue to slowly rise and when it hits the line right before redline I shut it down. While sitting it will take about 20 minutes to get to redline, driving a bit less. The temp won't even drop while driving 65 on the freeway, it more-or-less just doesn't go up. I have a 4.5in Rubicon Express lift, 32in BFG All Terrain Tires, stock 3.73 gearing, Random Technology catalytic converter maybe three years old, Borla cat-back exhaust 3 years old.
I made a rookie mistake and let a friend borrow my Jeep about a year ago and he let it overheat and blew the head gasket. Since then it hasn't been staying cool, runs really smooth, just won't stay cool.
The work I've done:
- New Head gasket
- replaced heads with reman head
- new water pump
- three new 185* t-stats(first two were bad out of the box)
- new three core CSF steel radiator
- new rad cap
- new hoses; Lower hose has a spring in it
- new temp sensor at the back of the cylinder head
- clutch fan replaced with three e-fans covering 90% of radiator; I have a switch on my dash to work the fans manually so I don't have to rely on temp sensor
- aux cooler for transmission
- Cooling system has been flushed and pressure tested
- cooling system has been properly burped with the heater running.
So I've done all this work progressively throughout the past year and like I said I need help...I'm at a loss. Any info would be beneficial. Thanks a lot in advance guys
