Installing the roof cowl

An opening is made at a suitable position in the roof
to install the cowl� Make sure that there is no electrical
wiring (e�g� roof-mounted air conditioning unit) or roof
reinforcement struts in the vicinity of the opening�
 Inform the vehicle manufacturer of the location of
any wiring or roof struts�
The distance between the centre of the opening and
side walls must be at least 55 mm or 60 mm�
Make an opening of 60 mm or 70 mm in diameter at
a suitable position in the roof�

 If the roof has a double layer, line the cavity with
suitable heat-resistant material (Fig� 25-1)� This will
stiffen the roof so that it is not deformed when the
screws are tightened and remains watertight�
 Sealing is done with the rubber seal (Fig� 25-2),
which is attached to the cowl� Do not use any other
sealant (silicone or the like)�
Insert the cowl through the roof opening from
above�
Tighten from the inside with the screwing ring
(Fig� 25-3)�
Secure the screwing ring with a screw (Fig� 25-4)�
