Hey all - I have a lengthy thread on CF.com about this but it seems to have run its course and a cross-post can't hurt.
95 4.0 5-speed on 35s/4.88s with a motor from a 97; it idles fine but temp likes to live just to the right of 210, but when I'm at 50MPH or faster, it gets up to 230-235 or so, and under load gets there quickly. It really wasn't an issue in the cooler months but now it really is.
I've replaced literally everything. Here's my list so far:
New:
Factory thermostat (tested, opened at 195)
Thermostat housing
Napa fan clutch
Spectra radiator
Hoses
Water pump
Radiator cap
Temp sending unit
I flushed the system and heater core multiple times. I did a compression test and everything was within spec, and I also tested for exhaust in the coolant and found nothing. What on earth could still be causing this??
Sure appreciate any advice!
