Figure No. 1 - Front Grille Cracks
Some 1985 - early 1987 M vans are experiencing cracks in the grille assembly at the upper left and/or right attaching tabs (Figure No. 1). This condition
is due in part to a misalignment between the grille tabs and the radiator support attaching holes. Insufficient hood to grille clearance resulting from loose
hood bumper-stop bolts also contributes to grille tab cracking.
REPAIR
A new grille assembly has been released to repair this condition. The new grille assembly outer tab thickness has been increased and the upper left
(driver's side) tab attachment hole has been changed to a 5 x 10 mm slot Hood bumper-stop bolt retention can be improved with the following procedure.
^
Adjust bumper bolts to achieve the proper hood to fender alignment.
^
Note the number of threads exposed at each bumper bolt.
^
Remove and clean the threads on the bumper bolt and the threads in the radiator support.
^
Apply Loctite Black Max (R) or equivalent to the bolt threads.
