This is the second highest point on the engine after the filler neck. When there have been air bubbles in the system, the indicated pressure goes up rapidly, more than temperature would warrant, to more than 30psi indicated. It helps me to know to get more of the bubbles out, and then pressure reads about 23psi at 190 on the coolant temp. Regards, Tommy<>< Re: Mystery of the leaking coolant In "The Book" Tracy strongly suggests installing a coolant system pressure gauge. It sounds like it might be a good suggestion, in light of the trouble you had. --- [Pre-scanned for viruses by Internet America.]
