Another overheating thread added lol. Searched through and didnt find a fix. Ok so ive got a 96 RS with a 3.8 automatic with a fresh rebuilt engine. Drove it myself for around 2 weeks and now its overheating. Everything has been replaced ie: water pump, radiator, 2 thermostats, and a temp sensor. The car does just fine down the highway but the fans wont come on to keep it cooled in traffic and turning the ac on makes no difference. I have swapped out the relays already and to no avail nothing is fixed. When i put the 2nd Tstat in it after replacing the temp sensor i warmed it up and it seemed to not build pressure on the upper radiator hose even after bleeding it, shut it off at around 250degrees and coolant shot out of the radiator so gauges are reading. Long story short no fans unless theyre run directly off of battery. Any thoughts?
