SUBJECT:
WASHER BOTTLES CRACKING
MODEL:
1988 - 1991 S/T TRUCKS
Some 1988 - 1991 S/T trucks may be experiencing a condition of windshield wiper washer bottles cracking and then leaking washer fluid.
This condition can be caused by an increased amount of pressure exerted by the two fastening nuts and screws. This increase in pressure causes the
screws to cut into the plastic and initiate cracks. To correct the situation new parts have been released with a wider flange, and the torque requirement
has also been revised. The new torque requirement is now 5-8 N-m (3.7 - 5.9 ft.lb.) instead of the old 8-11 N-m (5.9 - 8.1 ft.lb.). When ordering a new
washer bottle be sure and order new bolts and nuts with the revised flanges.
