A high pitched undulating wind whistle, starting at about 34/45 mph that can be heard by vehicle occupants as well as by a roadside observer may come
from air flow between the lefthand side of the grille and the fender. This condition may be serviced by modifying the existing lefthand headlight opening
side shield.
NOTE:
The retaining barbs on the shield usually break when it is removed. The replacement part is E3TZ-13B042-A. In either case, use the following
procedure to modify it.
1.
Remove the right and lefthand combination Park/Turn lamps (four exposed screws).
2.
Remove the (two) radiator grille retaining screws (one each side) now visible in the Park/Turn lamp cavity.
3.
Remove the (ten) exposed screws that further retain the radiator grille and lift out the radiator grille.
4.
Using a wide screw driver or gasket scraper, pry out the lefthand headlight opening side shield.
NOTE:
The retaining barbs usually break when the shield is removed. However, if the barbs do not break, the shield can be reused for the
modification.
