Unlike our original tapped housing, which uses a 1/8npt sensor that can not be removed, the EZ bleed housing uses a M12 sensor with a gasket.

The VDO sensor installed uses a ring terminal connection for your signal wire to the gauge.</p> <p> </p> <p>*Not recommended for use with a silicone upper radiator hose</p> <p> </p> <p><strong>Kit Includes:</strong></p> <ul> <li>EZ Bleed Aluminum Thermostat Housing</li> <li>Gasket</li> <li>VDO 250 Degree F Coolant Sensor</li> </ul> <p> </p> <p>Note: You must use a VDO temperature gauge for this to work.
