I have my car in at the dealership currently for a CEL. They told me its a MAF sensor and a coolant temp sensor. The MAF sensor is easy and I have an aem CAI. However, I don't know how to replace the coolant temp sensor. I know it's the sensor located on the radiator but was wondering if someone could help me out in figuring out how to replace it so I don't have to pay their outrageous charges. However, it may just be worth it so I dont get coolant everywhere.
