The following information describes which vehicles, equipped with a 4.3L V6 diesel engine, require altitude adjustments and which are "All Altitude"
systems.
1982 Federal Regals equipped with 4.3L V6 diesel engines (Engine Family C364.3D7ZZT7) were manufactured with either high or low altitude diesel
emission systems. Cars equipped with the high altitude emission system were invoiced with option NA6. The type of system can also be identified by the
emission label attached to the fan shroud. The label will indicate that the car was built for primary use at either high or low altitude. The following
procedures are considered altitude performance adjustments and apply only to in-use vehicles. They should not be used to modify vehicles prior to sale.
1982 California Regals and 1982 Federal and California Centurys equipped with 4.3L V6 diesel engines (Engine Family C3G4.3D7ZZK6) were
manufactured with "All Altitude" Diesel Emission Systems. Altitude performance adjustments must not be used on "All Altitude" vehicles.
