TH350 - where can i measure oil temperature

Warewolf SD · Apr 2, 2021

I used an aluminum block tapped three times to Tee one into the output to the cooler. Gives you an idea of how hot stuff is getting. Same theory of getting oil pressure after your heads and coolant temps at the cylinders.

Here's another screenshot taken from that RV forum I was in with GM instructions regarding both the output and sump. This explains it better than I did so not just trying to beat a dead horse here.

I'm running mine off the output to the cooler at the transmission. Use one of these and a shorty sending unit. Normally runs 160-180° can hit 210° on long climbs or beat downs.

My past experience ive used the output line before the cooler.
Basically what that last rv screenshot post was talking about is what i was told a while back.
Those temps get scary lol.
Only issue i ran into was the guage (electric sender) not reading because its not grounded being inline with a rubber hose.
