I just bought a 1998 Toyota Corolla with 139k miles on it. It is in great shape except for one issue: it runs hot (about 3/4 gauge). I had the cooling system flushed to see if it would help with no improvement. When I drove to work this AM I noticed the following:
1- It heats up/gets hotter while driving
2- It cools down a little bit when stopped at lights
3- It cools down significantly when stopped and I blast the heat
I have been going through the coolant flow over and over then rememberer the electric fans. With the car idling in the parking garage, I waited to see if the fans came on. Both fans come on when the temp gauge goes over 3/4 guage. And then cycle off, suggesting the fans are not coming on at the right temperature.
From my reading/research online, I believe simply unplugging the fan temp switch will cause the fans to run constantly in "fail safe" mode. Is this correct? If so, would you agree I should try making the 40 minute drive home with the fans running constantly to see if it resolve the temperature problem and, if it does, the switch is the culprit?
