C.Exchange Procedure:

Once the above preliminary diagnosis is made and an exchange unit is deemed necessary, call the TAC (Miscellaneous Group).

The TAC group will arrange to ship an exchange unit to your dealership and provide your dealership with a TAC reference number. This number must be written on the return engine intake plenum chamber, before returning the unit.

To increase the effectiveness of the program, the concerned unit must be returned immediately (not later than 1 week after date of receipt of replacement unit).

FAILURE TO RETURN THE CONCERNED UNIT WILL RESULT IN THE DEALERSHIP BEING BILLED THE VALUE OF AN EXCHANGE ENGINE.

All procedural steps must be followed to ensure that your dealership is not billed for this engine.

The removed unit must be returned complete as removed from the vehicle in the container provided, without examination of the unit other than as described in Paragraph A above. Engine dress on the removed unit must remain same as replacement engine was shipped (i.e. manifolds, throttle body, etc.). Dealerships returning units that have been even partially disassembled will be judged as violating this procedure and as such will be subject to being billed for all materials furnished.

The exchange unit will be shipped with minimum quantity of oil; add oil per specifications.


The exchange unit will have an envelope attached to it. This envelope will contain:

- Plastic bottles (for oil sample and coolant sample)
- Return shipping label (freight is prepaid).
- Leak identification charts.

NOTE: An exchange engine will be shipped within twenty-four (24) hours or one working day. The engine plant will make every effort to assure delivery to dealer within forty-eight (48) hours or two working days.
