Overheating...

Post by 99-SLE »

Just got back from a drive out to the mall, maybe 25k long. On the way out noticed car felt like it was driving "weird" Don't know how to explain it any better than that... sat in a drive thru and noticed my scangauge was reading 125C, it normally sits at when fully warm, between 85-90ish (not sure what that converts over to)

Once I exited, pulled into a spot, popped the hood. Not low on coolant, but noticed a slight bit of smoke/steam from the rear of the engine. Quickly dissipated, and could no longer see it. Gave the throttle a few blips, and it seemed to hiccup a bit. No CEL, or pending codes.

Decided F it, and jumped on highway for home. quickly cooled down to 95ish. Car has fresh coolant, new thermostat, as well as new UIM, and LIM, and gaskets. I have to drive back to BC on Saturday....

Also the odd time, I'll go to brake, and pedal sinks, nothing there, and then firms right up.....

Poked around a bit further... Turned on A/C, and fans didn't turn on, neither did they with defrost, even with it running at about 125C.

Will try finding the relay tomorrow (underhood panel I assume?) and swapping for a similar looking one to see. I have two fans, If it makes a difference
