Original BMW Engine Coolant Hose for BMW 2500, 2800, 2800CS, 3.0CS, and 3.0S (1968–1974)

BMW's genuine hose 11-53-1-251-520 is an engine cooling hose for the M30-engined BMW 2500, 2800, 2800CS, 3.0CS, and 3.0S (1968–1974). BMW names it simply a hose, and it belongs to the engine cooling system, the group that also holds the thermostat and the connecting pipes that keep engine temperature in check. It weighs 394 g (0.9 lb), and BMW production of this number began in September 1968. Coolant hoses carry coolant to and from the radiator and the other cooling components, so a sound hose is basic to keeping one of these classic M30 cars at the right temperature.

Original BMW Parts carry a 24-month parts warranty.

The same hose serves the E3 and the E9, so one number covers the 2500, 2800, and 3.0S on the E3 side and the 2800CS and 3.0CS on the E9 side. To tell a genuine BMW part from a copy, look for the BMW roundel stamp and the short seven-digit number, 1251520 on this hose. Genuine BMW parts are made by established suppliers, so a supplier's stamping alongside BMW's marking is normal.
