o.k. replaced the radiator that had a large crack in the top tank.

removed and filed off corrosion off grounds and put dialectric grease on all of it and refastened.

drove around and still gets almost up to 100! but as i was driving around defeated last-night, it looked like the gauge all of a sudden was driving right where i like it ~90ish. drove it up to 65 mph for a while and didnt move (same course that previously would bring it up to 100) and so i figured the system burped itself or the gauge sorted itself out.

Drove it in this morning to work and popped onto the highway for about 5 miles and then it steadily climbs to around 105. when i knock the gauge, it appears to drop to 95 sometimes and but immediately flicks back up to 105.

Got to work and turned the car off and felt that the radiator was warm up top but cool to the touch down low and the lower pipe was cool to the touch. is that normal? i would expect it to be a bit warm on the return.

the entire cooling system is basically new. new radiator, new water pump, new temp sensor, hoses, thermostat. the radiator cap tested OK by the radiator shop. the only thing left would be the instrument cluster....

Should i keep trying to burp the damn thing or replace the cluster or throw a match to the friggin thing!!!!!!!!?!?!?!?!?!??!?!?

Any and all advice appreciated. :wtf:
