Anyone know where to find a thermo switch for a 1985 928 I can't find it in the description at pelican or 928 specialists? ti had two vacuum ports and a cap.

There is one on the passenger side rear of the cylinder head that controls vacuum to the diverter valve if I recall correctly. I believe it senses coolant temperature and connects vaccum from the intake to the diverter valve for the air pump.

32v or 16v ?

32 valve, i will post a picture later. It has the numbers 928.110, 28.00, 5 004, 21112 01

I took a short loop of hose, and at the firewall, under the overflow tank, connected the vapor line from the tank, to the line which dumps in the middle of the back bumper, euro style. I removed the rest of the system, including the thermo-switch.

I think that might be 86-, though. Before 86, there is a hose that connects to the airfilter box instead of a line to the back of the car. 86 still have the hose barb on the filter box, but it is not drilled.

#17 is a thermo valve....is that what you're looking for?

mdarney

#17 is it! if I bypass it is it bypassed open or closed?

Bypassing that (#17) opens the diverter valve which sits in between the passenger side cam cover and the windshield washer resevoir filler neck.
