Thanks guys, and yes they did replace the hoses and clamps and as far as using the right coolant I would hope a Porsche dealer would know. My first thought this morning after I simmered down was air in the system also, but since it is a warranty isssue I decided not to take any chances and had it towed to the dealer. The technician was not in on Saturday so I will find out Monday what is up. On the funny side, the tow truck driver said that he just got done picking up a '63 boxster....I said yeah right, that was a great year...
