This kit is used with a garden hose to flush out an automotive cooling system. It comes with 3 different "T" adapters to connect into the heater core hose, a garden hose adapter, hose clamps, and an adapter to plug into the fill area of the radiator for the old coolant to get flushed out. AutoZone sells individual "T" adapters if you want to install them on more than one vehicle without buying another kit. It is universal for every brand, and model.
