Mike-The thermister part number is 102480. It is underneath the intake manifold. You will have to remove all of it to get at it. You will also have to sop up the coolant that runs out while you're changing it and re-bleed the cooling system after. Like I said, a very irritating problem. The intake manifold itself seals with six o-rings, one each around each intake port. There are other gaskets and seals involved for which we have a kit. Surprise. It's part number K111171.
