Re: TJ overheating with winch covered...
i guess i should back up a bit. about a year ago, i got in some deep mud that somehow got into the radiator (though the overflow i assume) and the jeep over heated. so removed the radiator, pressure washed the outside and flushed it internally. it still ran hot so, i replaced the tstat and bought some preston radiator flush. after a few weeks, the fluid was brown again so i flushed it several more times and it still ran hot. so i had it professionally flush at a radiator shop, replaced the water pump (it was leaking), put in a new tstat, and bought a new 3 core radiator. I haven't had any problems since. but sat, i threw the cover on the winch, went driving down the road (with a/c on) and next thing i know, the idiot light is on and the gauge was in the red. i turned on the heater to cool it down. took off the winch cover and had no problems since (even with a/c on) so my conclusion was that little extra area that the cover blocks is apparently the difference and if everyone that has a TJ, must leave their winch uncovered! am i wrong?
