Overheating while towing? Low weight.

Wetness is likely power steering fluid. Thermostat is inside the engine block, not an easy fix.


Id guess a normal radiator flush should make a big difference. Also make sure there no.blockage in front of the radiator fins.

I towed 3-4000 lbs 4 hours across the Appalachain mountains with no problems. Outside temp was around 80 deg

Done this a few times

FWIW, isn't the thermo supposed to be "fail safe"...

As in, it'll stick open, rather than closed, if it goes FUBAR?

So does it overheat when you're not towing? Five hundred pounds isn't much weight. Seems like if it overheats pulling 500 lbs it would be overheating all the time...

Ldub, the OEM thermostat isn't the failsafe type. If the diaphram doesn't hold wax, the thermostat won't open.

for the heads up...

I made a false assumption....

Maybe trailer bearings?...
