5.2 Ultrasonic Sensor Serial Number Arrangement

When installing the sensors, start with the smallest serial number on the left-hand side, and
proceed to the largest serial number on the right hand side. Each sensor has a serial number

stamped on the sensor housing.

Apply a light coating of the supplied Permatex Anti-seize grease to all threaded
parts upon installation.
