This is a replacement sensor for the BennettBuilt coolant tank. Thread sealant is applied to the sensor before shipping. Simply thread this sensor in until tight making sure the arrow on the side points down.
When installing this sensor, the coolant tank must be sitting on the opposite end from the sensor to prevent the sensor from breaking during installation! This is to keep the sensor straight up and down while turning otherwise the sensor will hinge and get caught on the tank causing it to fail.
