I'm driving myself crazy looking for a 1985 EGR Temperature switch. I've just bought the car and am pulling the plenum/etc for cleaning and want to replace parts while I've got it off.
Apparently this is a single year model switch and I can't find anything except the 86+ version, which I'm sure closes at a different temperature based on it's location.
I'm starting to wonder if I need to find a way to make one. If I knew the open/close temperature I might be able to. Does anyone know of a source, alternate, or work around for this?
Look for a Z28 temp switch from 85-89. The Z28 EGR switch was the same all years as the 85 only Vette part. Its rare but it may help expand your search.
Thanks, I'll keep an eye out. Not seeing anything right now. Really wish I knew the temp open/close as I might be able to cobble something together if I did
