for some odd reason the fan began to work again. but the temp gauge is jumping up and down. this is puzzling to me. never had one act this way.daytonafanatic said:fan isn't coming on. unplugged temp sensor at the themostat. fan then came on. can anyone tell me whats going on. just pulled the 3.0 out of a 91 daytona and replaced it in my 90 model. even changed wiring harness inside and out. the fan was working in the wrecked 91.
