Upper radiator hose tee/bleeder
The hose fitting shown above is for installing the LS1, LS2, or LT1 steam vent tube into the upper radiator hose.
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 engines use a 3/8" fitting. The fittings are standard 1/8 npt fittings, and can be replaced for other applications.
Also available are steam vent tees with sight glasses to monitor coolant foaming and air in the system.
