SHACMAN Coolant Return Hose DZ97259539024 The DZ97259539024 is the coolant return hose that runs between the expansion tank and the engine cooling circuit on SHACMAN heavy trucks. It feeds coolant back to the tank while the system expands and contracts, which keeps the pressure in the circuit within its normal range. The hose is built from moulded rubber with a metal fitting on the end, so it seals onto the tank outlet without extra adapters. It is kept in stock for SHACMAN
