Subject: SUNROOF WATER LEAKS


1985-87 SUNBIRD COUPES
Bulletin revised to correct part number for hinges from 206950 to 20696950. Please discard bulletin 87-10-35 issued 2/88.

Some Sunbird coupes with a sunroof may develop a water leak. This may occur between the glass and the seal near the center line of the car and could be the result of the glass contour. If the glass contour and the roof do not match, the glass should be replaced with new glass, part number 20717541.

This new glass has been contoured to match the coupe roof line and was introduced with the start of 1988 production. The new contoured glass is only for the coupe sunroof application and may be identified by a "C" marking in the glass monogram block.

It is also important when correcting water leaks on 1985 and 1986 models, to use the new hinges, part number 20696950 which were released in July 1986 to address wind noise and water leaks due to hinge deformation.
