Nice, Olaf! I'm going to have to study this and learn about cooling stuff!
Oh, tiny note: the 'intake air temp sensor 0-ring' fits the temp sensor on the lower hose of the radiator...so if someone wants to save $10 or so and not buy a new sensor, that's the 0-ring to get.
I'm so depressed. No one wants to come see me. :(
Mangofy your E46!
