Beck/Arnley 143-0822 engine coolant thermostat housing assembly for the 1994-1999 Mercedes-Benz S420 V8 4.2L and other vehicles combines the thermostat and its housing in one unit. As the engine warms, the thermostat opens to let coolant flow toward the radiator.
A coolant leak at the housing, overheating or an engine that is slow to warm up can be signs of a failing thermostat. A weak water pump, a leaking radiator hose or a faulty coolant temperature sensor can produce similar symptoms, so find the source before you buy.
It is listed for a wide range of Mercedes-Benz models, including the 1994-1999 Mercedes-Benz S500 V8 5.0L and the 1998-1999 Mercedes-Benz CL500 V8 5.0L. It is made to match OE form, fit and function.
