Express 3/4 Ton Van V8-4.8L VIN V (2003)
The torque specification has changed for the fittings to case. The torque has changed from 38 Nm (28 lb ft) to 32 Nm (23 lb ft).
Tighten
Tighten the new cooler fittings to 32 Nm (23 lb ft).
The converter drain back check ball (420C) has been removed from the cooler line fitting and is now located in the channel plate.
If you get a concern of no movement in the morning or after sitting for several hours, the cooler check ball should be inspected.
The best way to determine where the check ball is located is to look at the cooler line fittings. The old fittings are different sizes (3/8-18 NPSF & 1/4-18
NPSF) and would contain the cooler check ball. The new fittings are the same size as each other (9/16-18 UNF) and do not have a cooler check ball.
