Beck/Arnley Engine Coolant Thermostat P/N:143-0799
Beck/Arnley 143-0602 thermostat for the 1994-2002 Mercedes-Benz SL600 V12 6.0L and other vehicles opens and closes to control coolant flow and keep the engine at its working temperature. The Beck/Arnley thermostat is a direct replacement for the original, with the form, fit and function matched to OE.
An engine coolant thermostat that sticks can lead to overheating or a slow warm-up, though low coolant or a leak can lead to similar symptoms. With the engine off and cool, look at the coolant level and the hoses and joints for leaks first; a shop can test the thermostat itself.
The vehicles it fits include the 2005-2007 Mercedes-Benz SL65 AMG V12 6.0L and the 1994-1999 Mercedes-Benz S320 6-cylinder 3.2L, along with many other Mercedes-Benz and Volvo models and more. Each engine takes one thermostat. If your car isn't named here, enter its year and engine in the "Vehicles it fits" section.
