Here is the internet explenation of what this "spacer" does. Can't find it new. My 76 came with it for a reason....since I stripped mine, I'm looking for another....maybe still stuck on one of the heads laying around somewhere



Workarounds:
Recently I came across a section in the ProTraining manual that said, "A temperature spacer 022 133 079 is available for cars which run well on initial start-up and when fully warm, but have performance problems only during warm-up. This spacer does not affect the resistance values when the engine is cold or when it is fully warm, but it does delay the change in resistance during warm-up, The spacer temporarily insulates the temperature sensor housing from the heat of the cylinder head".

This is a common problem and I've experienced it myself. When I researched the issue I found no information only stories from other owners with the same issue. It seems many are content to suffer through the warm-up until the bus is at operating temperature when it seems to operate correctly.

I always wondered what item #14 was in the fiche alongside the temp sensor (item #41) and it appears to be this spacer. When I get my hands on one I'll try it out. The aircooled Vanagon CV engine has no such spacer available but the parts diagram for the FI Superbeetle does.
