A follow-up on my oil pressure switch replacement (1990 K1500 5.7L): works
great now- thanks for the help!
BUT, my manual (1990 GM Service Manual- "the big one") said the switch was
located on the driver's side, above the oil filter. The Haynes manual said
the same thing. Looked at that location: there was a hole alright- and it
was threaded for the switch- but it was empty.
First thought: someone removed it and plugged the hole
Second thought: couldn't be b/c the gauge is working, only inaccurate
2 hours later, went to the least helpful manual I have just to see if
something was different in Chilton's: voila! It indicated the switch was on
top, by the distributor! Bingo! The third manual wins!
My ex always thought it was weird that I had different manuals on the same
vehicle but here was a good reason why! Anyone know when the change
occurred? Would a 1991 GM service manual be more accurate for a 1990 K1500?
Thanks again to everyone who helped with the problem!
