Cooling system Volvo 1800 (1967-73)

The group includes radiators and radiator hoses, water pumps, hose clamps, expansion tanks plus seal rings and O-rings for connections and the pump gasket. During a cooling-system overhaul, the water pump's shaft play and any coolant leakage from the weep hole are typical check points – a worn pump bearing often makes noise before it gives out. Take the chance to replace cracked hoses and tired clamps while the system is drained anyway, so you avoid another teardown shortly afterward. If the car has the BW35 automatic, the radiator's connection for transmission oil can differ, so check the design before you order. The families cover both upper and lower hose routing as well as seals that often dry out and start to weep over the years.
