Gates Radiator Coolant Hose P/N:21603
Gates 22234 upper radiator coolant hose for the 1997-1998 Mercedes-Benz C230 4-cylinder 2.3L and other vehicles carries engine coolant between the engine and the radiator.
A hose that is cracked, bulging or leaking at the ends can be wearing out, though overheating and coolant loss can have other causes. Before you replace the hose, rule out a faulty radiator cap, a weak thermostat or a leak at another connection. Each engine takes one upper hose, so this single hose covers it.
It fits the 1997-1998 Mercedes-Benz C230 4-cylinder 2.3L and the 1994-1996 Mercedes-Benz C220 4-cylinder 2.2L.
