Trunk - Procedure for Additional Ventilation

88jaguar01

TRUNK VENTILATION
SECTION: 76
No: 18
Model: XJ-S Date: JANUARY, 1988
KEY POINTS: ADDITIONAL AIR FLOW FOR TRUNK VENTILATION
Additional trunk ventilation can be achieved by increasing air flow from the passenger compartment to the trunk area via two extra vent assemblies mounted above the rear parcel shelf. This air is then ducted to the atmosphere through four vented grommets fitted to the trunk floor. This modification is incorporated into all XJ-S coupe vehicles from VIN 142987.

To carry out this modification the following procedure should be followed:

1. Remove the rear seat cushion and backrest, rear seat belts and rear parcel shelf trim.

2. Remove the spare wheel, fuel pump cover, fuel tank trim cover and floor carpet.

FIGURE 1:

3. Mark out the parcel shelf rear vertical panel (Fig. 1, A) for fitment of the vent assembly.
4. Using a 1.5" hole saw, cut four holes as directed. Drill eight holes 1/8" for the vent assembly fixings. Apply paint primer to any exposed bare metal.

5. Apply Seelastrip or similar to the vent assembly's mating face and place in position from the trunk side (Fig. 1, B). Secure the assemblies with pop rivets from within the passenger compartment.

6. Place the parcel shelf assembly onto a clean surface, remove the retaining clips and separate the panels.

7. Discard the rear trim panel, BAC 5566PA and replace with the new vented panel, BDC 4024PA. Refit the clips and refit the assembly to the vehicle.

8. Refit the seat belts, seat squab and cushion.

9. From inside the trunk mark out and cut two 15/16" holes into the trunk floor (Fig. 2) (NOTE: Left side of trunk floor shown). Apply-paint primer to exposed bare metal and fit two additional vented grommets BD 46778, ensuring that the vents face to the rear of the vehicle (Fig. 2).
NOTE: It is important that air flow to the grommets is unrestricted. It may be necessary to trim back the trunk floor carpets.
