94 S-10 Overheated Now..........


Recommended Posts

Posted

My 4.3L S-10 got real hot today (235) and I now have a rough idle and exhaust sounds deeper and a tick in the engine now. The radiator didn't boil over or anything like that. I just noticed it was between the 210 and 250 temp on the gauge. :chevrolet: Any ideas what may have happened? Is it serious?? It overheated with the AC on so i turned it off and it cooled back down to 185 but now I have all those things going on. I drove it home without the AC and it stayed 185-190 which I think it has a 185 T-Stat in it anyway so I assume that's the right operating temp. Any ideas? Thanks for your input.

Try changing the thermostat, cheap thing to do. Also check the oil and anti freeze. Make sure that they aren't blending in either system. if they are your intake gaskets could be gone or your head gaskets are.

OOPS! I guess I should dig around under the hood more before assuming the worst. A plug wire came off and when I put it back on all my problems disappeared....... :D Thanks for the input! :wtf:
