I have a 2007 Monte ss and I just got a cold air intake and PCM put into the car after that I had a problem with overheating do to what I thought was because of the relocation of the coolant res. I bought a universal bottle and placed it back up in the original place... Worked like a champ no problems. I just got my AC fixed and not 20 min after driving it in stop and go traffic my AC shuts off and I begun to overhear never reaching the red but above normal operating temp. Anyone have any ideas
