Do you remember the part in Dogma...

...where Jay is driving and the engine is revved pretty high, and Bethany leans up and asks, "What gear are you in?", and Jay says, "GEAR??!"

Well, that's what went through my head when I pulled the coolant header tank off the cylinder block to inspect the gasket and the thermostat.

Wait... there's no thermostat!

Please note the blue circle and arrow.. yes, there is something missing. :+)

Jeremy of Jeremy and Colleen fame had given me a spare thermostat he had laying about from his Perkins 4-108. How convenient! So, when I put the engine back together there will one less part to source. Hooray!

No thermostat, thats crazy. I should have checked sooner.
