Geez, I know that headgasket #3 cylinder is a culprit - however, many many G2 owners experience overheating that is not the headgasket and Ladies and Gentlemen I am here to tell you that Chris Wade... LMAO... didn't listen. He had is headgaskets replaced at the suggestion of his mechanic at 124k because his temp was going up and down, from mid-point to red and then back to mid-point. Guess what. I drove him to pick up his ride. Not ten minutes down the road he had the same problem. Drove it to Acura - cost 79 to diagnose and repair (the applied the diagnostic fee to the repair action) a connector that had literally rotted. I felt bad for him that he dropped that many duckets, and his mechanic doesn't have the meter that detects exhaust gas in the radiator. He fell into the... could be hairline cracks, headgasket problem, and the recommendation of his mechanic freaked out. More or less went into the Auto Import Specialties and told them what he needed done.
All I'm saying is before you drop approximately 1 to 1.2 theeeeousand dollas - go to Acura, get a printed diagnostic of the repair required to return your vehicle to normal operating specs.
