How do I change out the coolant temperature sensor?
What is your question?
Back in Dec.25,2015, I mentioned that I was having problems with 1994 Geo Prizm. I took it to a shop, and found out that my coolant temperature sensor, stopped working. That's why the fan wouldn't turn over like it was supposed to. Even though the fan switch works, I decided I would like to change it out the coolant temperature sensor myself to save a few dollars. Someone gave me advice on how to do it, he said to heat up car, and as it starts to cool down put a rag on the sensor and tap on it until breaks loose, and then unscrew it. Is that true, PLEASE HELP! I rather do it the correct way, and avoid costly repairs later.

That's a good way to get scalded!!!!!... With engine COLD, use a deep well six point socket, ratchet & extension to R&R sensor!.. Theres nothing special about it, have done a BUNCH of times!!!
