Four Seasons Engine Coolant Temperature Sensor P/N:37906
Four Seasons 37825 switch for the 2006 BMW 650 Series and other vehicles is a coolant temp sensor switch that reads engine coolant temperature.
A temperature gauge reading that jumps around, or a check engine light, can mean this switch is failing. Before you replace it, rule out a low coolant level (check it only with the engine cool), a damaged wire or a loose connector, since those can lead to similar readings.
The 2006 BMW 650 Series, the 2006 BMW 650i and the 2000-2006 BMW X5 are among the vehicles this switch fits, along with other BMW and Land Rover models. If your car is not named here, find it on the Buyer's Guide tab, which also shows the engine for each application.
The switch comes with gaskets, o-rings or seals for a proper replacement.
