I honestly don't know.
But he's a very reputable Porsche guy here in Lawndale CA.
He was pretty insistent that there is no air in the system when I asked him earlier today.
I was unable to ask him before he closed for the 3 day weekend if he uses a vacuum or not.
But what doesn't make sense to me is that if there is a circulation problem as he indicates, why wouldn't the temp go up or it overheat?
A second opinion mechanic (a very reputable guy in OC) told me to drive it tomorrow stone cold and not refill the coolant and see what it does.
He also suggested a test for hydrocarbons in the coolant.
Please weigh in, there are some very kind and knowledgeable people here who do not have skin in this game.
Thank you.
