CRANKCASE VENT FILTER
All engines have a crankcase vent filter. The filter
cleans outside air before it enters the PCV system.
On 2.5L engines, the filter mounts to the upper shell
assembly of the air cleaner. On 2.5L MPI (Flexible
Fuel AA-body) and Turbo III engines, the filter at-
taches to the inside of the filter element box, next to
the filter element. On 3.0L engines, it attaches to the
inside of the filter element box under the filter ele- ment. On the 3.3L engines, the filter mounts to the
bottom of the filter element box. Refer to Group 0 for
mileage intervals and service procedures.
