[QUOTE="SkooterG, post: 235699, member: 118"] Thanks all. I too, was leaning towards the thermostat having some sort of sealing properties. It's not the taking apart I am worried about. It's the putting it back together! You know, I considered that area as a source of the leak, but I spent A LOT of time trying to find the source and while I can't see everything, I am reasonably certain that the leak is not coming from there. Still....... An excellent point. But I was REALLY thorough. Damn. Guess I am going to have to order up some new O-rings and a thermostat and take everything apart. I REALLY don't want to do that, but looks like I have no choice. #33 being a bleed screw also makes sense and was what I was thinking, but here's the problem: The service manual has ABSOLUTELY NOTHING about that screw or a procedure for bleeding the thermostat housing. So how, and when would you bleed? I mean, I have drained the cooling system several times and never bled the T-stat housing. [/QUOTE]
