I checked the coolant and it is about 1" below the minimum mark, which is bad. According to the guy I talked to at the Porsche dealer, if the coolant level is low the engine could be heating up more than the gauge is showing. Is that true?
Also, should I just add coolant, or should I flush it?
Thanks!
