Help 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 1994-1996 Mercedes-Benz C220 and the 1986-1990 Mercedes-Benz 300E. See the "Vehicles it fits" section for the full list and to confirm your exact vehicle.
- Gauge input: sends engine coolant temperature information to the dash instrument gauge.
- OE-matched: designed to match OE form, fit and function for foreign-nameplate applications.
- Calibrated: made to exact resistance and temperature specifications per the application.
- Construction: made with high quality material and componentry and constructed to withstand an engine environment.
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.
