Beck/Arnley Engine Coolant Temperature Switch P/N:201-1522
Keep an accurate coolant temperature reading on your dash with the Beck/Arnley Engine Coolant Temperature Switch (P/N 201-1528, also written 2011528). This temperature sending switch provides water temperature information to the dash instrument gauge, and it drops in as a direct replacement across a wide range of older Mercedes-Benz models — including the 1974-1983 240D, 1975-1981 300D, 1986-1990 300E, 1973-1980 450SL, 1986-1990 560SEL and the 1994-1996 C220. See the Buyer's Guide tab for the full 31-application list and to confirm your exact vehicle.
Signs this switch may need replacing include an erratic, stuck, or non-reading temperature gauge. Because those symptoms can have other causes, diagnose the circuit before replacing.
