Parts Needed

Dealers will need to order parts for this Program.

1 - 7C2519 Hose (needed only if the existing hose is cut)

Action Required

Loosen the hose clamp nearest the inlet manifold, and inspect the hose for any signs having been cut. If the hose has any signs of having been cut, replace it with a new 7C2519 Hose. Tighten the clamps to a torque of 7 N·M. Refer to the Illustration below for location of the parts.

NOTE: Products equipped with an air inlet heater are NOT affected by this Program because a different air inlet elbow is used.
