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.

I am not aware of any engine oil cooling system, but I am old school. If you are refering to transmission cooling, yea, if no aftermarket, it cools through the radiator.

 

Most GM's of this era have an engine oil cooler in the radiator on the opposite side of the tranny cooler, the lines run from the engine via fittings at block for the oil filter.

 

Thanks, I didn't know that.

 

This might be of some help.
How do you remove the engine oil cooler adapter from a 91 350 and reinstall fi
