Hello all
I been wandering around this site for an hours now but not finding what I'm looking for (lots of other good stuff found!)

Chevy, 1990 Z71 extended cab, 4 x 4, 350, auto

Where is the oil pressure sending unit?
Part #'s for the engine oil cooling lines (no luck at Napa)
Diagram & discription of the engine oil cooling system
Is there a tech section on this forum with info?

thanks!

I have the factory manuals but no good info.

 

The oil press switch is located behind the dist. A dealer should be able to provide part numbers. A visual insp. should provide routing of oil cooler lines.
