Inspection and Adjustment

INSPECTION

Wind Deflector

1. Open glass lid assembly fully.
2. Visually check for proper installation, damaged/deteriorated components, or foreign objects within mechanism.

   Correct as required for smooth operation.

3. Check for grease at the wind deflector arm (1) and pivot areas. If necessary, apply a sufficient amount of grease for non-binding operation.

4. Check that the wind deflector (1) moves freely within the sunroof unit assembly while manually pressing down and releasing. If a malfunction is detected, remove the sunroof unit assembly and visually inspect; refer to RF-158, "Removal and Installation". If damage is found, replace either wind deflector (1) or sunroof unit assembly as required.

Link And Wire Assembly

NOTE: Before replacing a suspect part, make sure it is the source of noise being experienced.

1. Check link to determine if coating film has peeled off excessively enough that substrate is visible. Check also to determine if link is the source of noise. Replace as necessary.
2. Visually check to determine if a sufficient amount of grease has been applied to wire or rail groove. If not, add grease as required.
3. Check wire for any damage or deterioration.

Weatherstrip

1. Visually check weatherstrip for damage, deterioration, or deformation.

• Open glass lid partially to inspect front edge of weatherstrip.
• Tilt up glass lid fully to inspect sides and rear edge of weatherstrip.

If any area of the weatherstrip is found to be damaged, replace as required.

2. Check for leakage around glass lid assembly.

• Close glass lid assembly.
• Pour water around surface to determine area of concern.

• For gaps or misalignment, adjust glass lid to specifications. Refer to ADJUSTMENT in this section.
• For damaged sealing surfaces, either replace glass lid weatherstrip, or repair the sealing panel.

ADJUSTMENT

CAUTION:

• Always work with a helper.
• Handle glass lid assembly with care to prevent damage.

NOTE:

• For easier and more accurate installation, always mark each point before removal.
• After any adjustment, check sunroof operation and glass lid assembly alignment.

INSTALLATION

WARNING:

• Keep heat and open flames away as primers and adhesive are flammable.
• The materials contained in the kit are harmful if swallowed, and may irritate skin and eyes. Do not let them contact the skin or eyes.
• Use in an open, well ventilated location. Do not breathe the vapors. They may be harmful if inhaled.

  Move immediately to an area with fresh air if affected by vapor inhalation.

CAUTION: After installing the sunroof unit assembly and glass lid, perform the leak test and check that there is no air or water intrusion.

NOTE:

• Use a genuine Nissan Urethane Adhesive Kit (if available) or an equivalent and follow the instructions furnished with it.
• Inform the customer that the vehicle should remain stationary until the urethane adhesive has completely cured (approximately 24 hours). Curing time varies with temperature and humidity.

1. Using a knife or spatula, trim the adhesive (sealant) remaining on body down to approximately 2 mm thick (a) so that the contour becomes smooth.

CAUTION: If bonded area on body is scratched, be sure to repair it with a 2-component urethane. Do not use lacquer.

2. When installing new sunroof unit assembly frame, mount the roof frame dry (no adhesive) first onto the vehicle and paint mating marks on body and sunroof frame, then remove sunroof frame again.

4. Apply primer to the body and the sunroof frame (lower) surfaces.
5. Apply adhesive along the entire circumference of the sunroof unit assembly frame contact area of body within the time specified in the instructions for the adhesive.

• Open adhesive by cutting off the nozzle tip and set it in a sealant gun.
• Form a continuous bead of adhesive resembling the measurements in applied thickness (A), and in applied width (B) on the body panel.

Adhesive applied thickness (A) : 13 +- 1 mm (0.51 in +- 0.039 in)
Adhesive applied width (B) : 8 +- 1 mm (0.31 +- 0.039 i

7. Press down lightly by hand only on the frame to expand the adhesive contact completely so that it resembles a compressed thickness (A), and a compressed width (B) between the sunroof unit assembly frame and the body.

Adhesive compressed thickness (A) : 5 +2/-1 mm (0.20 +0.079/-0.039 in)
Adhesive compressed width (B) : Front edge 15 mm (0.59 in)
: Side edge 21 mm (0.83 in)
