Scope 2 (cont’d.) 2.4 Use a round steel-wire brush to grind all corroded areas on the folded seam on the inside of the lid.
Note: Do not use a brass brush. Brass particles can cause electrochemical corrosion in the seam.
2.5 Clean the ground areas with thinner, then apply primer with a small paintbrush. Make sure the
areas are completely covered with primer, particularly the corners and edges. The drying time
of the primer is approximately 1 hour. Using a fan to dry the primer can shorten this time.
2.6 Seal the rear edge and the left and right sides of the folded seam (arrows, figure 2) as follows:
- Apply adhesive tape on the sides of
the folded seam so that the folded
seam is exposed 3 to 5 mm.
- Apply sealant on the folded edge,
spread smooth, and remove the tape.
- Allow the sealant to dry for approxi
mately 4 to 5 hours. Moistening the
applied sealant with water can
shorten the drying time.
2.7 Paint the primed and sealed areas fol-
lowing the instructions in the Porsche Paint Manual, Group L 5. Figure 2
2.8 When the paint is dry, reinstall the seal on the lid.
2.9 Install the lid on the vehicle using the reference marks made to line up the hinges. Install the
bolts and tighten them up lightly.
2.10 Close the rear lid and adjust the gap dimensions. Tighten up the bolts.
2.11 If the latch was removed, install it and align it with the lower latching point. Torque the bolts to 7.5 ftlb.
2.12 Connect the electrical connection and attach the harness to the pneumatic spring on the right hinge.
2.13 Carry out a function test on the rear lid and on the 3rd brake light in the spoiler. On the
cabriolet, check the functioning of the microswitch for the rear-lid/convertible-top interlock. With
the rear lid open, it should not be possible to operate the convertible top.
2.14 Cabriolet only – If a fixed “Carrera” spoiler is fitted, open and close the convertible top gradually
and have a second person check the clearance (A, figure 3) between the convertible-top
compartment lid and the “Carrera” rear spoiler. The dimension must be at least 5 mm.
2.15 Enter the service action into the Warranty and Maintenance booklet.
