Gents,
Trying to find 2 parts and I have no clue what the name is. Engine is a 216

1. Engine block (water jacket) Drain plug. “T” handle looking plug on the drivers side of the truck that drains the antifreeze.

2. The shut off valve to stop antifreeze from going to the heater core.

If you guys know the names, I will go research them.

Thanks,
Chris
