EXHAUST - 3.0L AND 4.0L - ALUMINIZED MUFFLER CORRODES PREMATURELY
LIGHT TRUCK:

ISSUE:
The aluminized muffler may corrode prematurely on some vehicles. This occurs because the aluminized cold rolled muffler material may be susceptible
to rust under certain conditions.
ACTION:
If service is required, replace the existing muffler and outlet pipe assembly with a stainless steel muffler and outlet pipe assembly which is more
corrosion resistant. Refer to the 1992/1993 Aerostar Service Manual, Section 09-00, for the removal and installation procedures.
