The upper fitting (petcock valve) allows bleeding air out of the cooling system. It uses a standard 1/8 npt fitting.

The hose fitting for LS1 engines is normally 5/16" on early LS1 engines, but later engines (LS2) use a 1/4" fitting. LT1 engine use a 3/8" fitting. The fittings are standard 1/8 npt fittings, and can be replaced for other applications.
