This kit fits Cummins-powered trucks and covers the coolant routing between the radiator, engine block, and heater core with three hose sizes (one, five, and one piece) plus two smaller clamps and twelve larger ones. It supplies a matched set of hoses and clamps so the full coolant hose run can be replaced without sourcing each piece separately.
