Bonding Sensor Bracket In Radiator Protective Grille

Bonding Sensor Bracket In Radiator Protective Grille

When bonding the sensor bracket in radiator grille, take special care that the sensor bracket is aligned centrally to the punch hole in the radiator protective grille, since there is no enclosing joint present on the sensor bracket in this case. Should the sensor retainer not be perfectly aligned straight and centered relative to the sensor location (punched hole) in the radiator grille, the coupling ring will be stressed upon installation of the sensor, and system function may be adversely affected. Before proceeding with bonding procedure, ensure sensor retainer and radiator grille materials are between 15 °C and 25 °C (59° and 77 °F).

Procedure

- Clean the adhesive surface on the inside of the radiator grille thoroughly with isopropyl.






1. Sensor for parking aid.

2. Decoupling ring.

3. Sensor mount.

4. Adhesive surface on the inside of the bumper.


- Apply the bonding agent "Scotchmount 4298" evenly in the adhesion surface around the punched hole.

- Let the adhesive air dry for approximately 5 minutes.

- Allocate the sensor brackets to be bonded to their proper installation location.

Front bumper cover, refer to=> [ Sensor retainer allocation in inner side of front bumper cover from MY 11 ] Left Front Parking Aid Sensors (G255)/Front Right Parking Aid Sensor (G252).

- Insert chrome-covered sensor - 1 - into sensor bracket - 3 - until both retaining clips click into place.

- Remove both protection foils from sensor retainer bonding area - 3 - so that a gray surface becomes visible.

- Align the sensor head exactly in the middle of the punched hole in the radiator grille.

If sensor head is not aligned exactly in the center of the punch hole in the radiator protective grille, the decoupling ring (black silicone ring) on the chrome sensor is under pressure after installation, causing parking aid system malfunctions.

- Press the sensor bracket 2 with significant pressure into the radiator grille for approximately 10 seconds.

The contact pressure and pressing time are crucial for the adhesive durability!
