Hey all,

ive researched here trying to diagnose a overheat at idle problem. Fuses/relays seem good by visual inspection. Condenser fan comes on with a/c but cooling fan does not at operating temp. I added some coolant recently since problem surfaced a week ago, and that seems to have helped a lot. But fan not coming on. I’ve bought a new thermostat to replace to see if that’s the issues. Would the coolant temp sensor throw a code if it was bad or should I replace too? Or maybe it’s just a bad cooling fan??
