running to cool

Can anything other than the thermostate make my jeep run to cool. ( about 125) I've changed the
thermostat twice and it's still running cool so the heat isn't very warm.

A sticky clutch fan could be the culprit.[img]/wwwthreads_images/icons/wink.gif[/img]

Re: running to cool

Could it be that you're in Pennsylvania and its butt-f*ck*n COLD up there!!!???

Seriously, though, since you have a 401, i doubt TOO much cooling is an issue, so check that fan clutch, and also this may sound crazy, but be sure that the gauge is reading correctly. Your coolant temperature sensor may also be done for. I cant tell you much more...

Re: running to cool

in the winter i usually keep a piece of cardboard in the jeep a little smaller than the grill for freeway driving. my engine gets overcooled when driving fast when its below about 20 degrees outside.

Re: running to cool

Check the sensor that could be it, also put a real high tep thermostat and see if that does anything. Also it could just be the cold weather, when was the last time you flused your coolant, now might be the time to do so.

Re: running to cool

Flushing the coolant? How would this help make it run hotter... I think if there was some sort of cloggin or anything the engine would probably run hotter..
