Cooling lines on turbo 350-which is oil out, which is return?
I have just purchased an external transmission oil cooler for the roadster pickup, and the recomendation is that it be hooked in series with the cooling loop in the bottom of the radiator, downstream from the radiator, which would be in the return line leading into the turbo 350. On a turbo 350 the 2 oil cooling ports are vertically aligned, one above the other. Does anybody know which of these ports is for the return line?
THM 350 cooler line ports
Got yer info right here, straight from a 1980 Chevrolet Light Duty Truck Service Manual:
page 7A-17, upper left hand corner, shows a picture of a Turbo 350, with a label for the upper port as the pressure line to the radiator, and the lower port as the suction line (return) from the radiator.
So there's a bonafide reference to back up what the other guys have already told you.
