My Saturn is a 1.9. Gets 30 mpg without fail, however, if I am in traffic with the AC on or off it will overheat within 15 minutes + or -. I have taken it to several good mechanics who have changed the fan motor to no avail. Please help me. Pastor Timothy ---

The radiator fan circuit also includes a coolant temp sensor and a relay. If either of these are defective, the fan won’t operate. Were either of these checked out? Tester ---

Has your cooling system ever been flushed out? This type of thing needs to be done every 50-60,000 miles on that year car. A partially plugged cooling system and a fan that will not turn on can cause severe overheating. Both should be checked out. You “good” mechanics should have used some diagnostic skills. I can change a fan motor in a few minutes, but if the switch is defective, the problem will remain. We call such maechanics “parts hangers”. In the medical profession they are called “quacks”.
