I don't have any coolant leaks and I don't appear to be loosing any coolant. I don't see any bubbles or other indications of a head gasket leak.

My fan switch and thermostat are all "stock" (80C) so I think they match. I'll check that later. The fans pretty much turn on and off as they should.

I have a laser infrared temp gun. The temps read on that seem to match the gauge. If I shoot the area at the bleed it is about 90C, the area at the sender is hard to shoot but I think it is a bit hotter.

I'll research the Autozone tool. I'm pretty friendly with the local guys. Porsche isn't the only "odd" toy. I have an Early Bronco with a lot of not-Bronco parts too... I guess I'll try some water wetter. 30 degs... we'll see.

Any other ideas? I really appreciate the help! I'm out of ideas...
