Thermo Valve Location

PURPOSE

To provide control over EGR operation based on coolant temperature.

LOCATION

Located on the thermostat housing, 

CONSTRUCTION

The valve, is a thermo-wax type.

OPERATION

As the engine temperature rises above a preset point, a wax element in the unit expands moving a mechanical valve in the unit. This closes off the
vented port (closing the valve) providing vacuum to the EGR valve.
