If your dealership receives a customer concern on this engine, follow the procedure below.

A. DIAGNOSIS ------------ If any internal engine components require replacement, the engine must be exchanged. Only the valve rocker covers and the oil pan may be removed to determine whether the engine must be replaced. If a replacement engine is needed, any of the above mentioned parts that were removed must be reinstalled (i.e., complete engines are required for exchange).

C. PREPARATION FOR SHIPPING --------------------------- The removed engine must be returned in the container provided, without examination other than as described in section A above. Engine dress must remain the same as the replacement engine (i.e., manifolds, throttle body, etc.). Dealerships returning units even partially disassembled will be judged as violating this procedure and as such will be subjected to being billed for all materials furnished.

After the Bill of Lading has been dated and signed by the carrier, retain the last copy with your repair order and provide the other two copies to the carrier. Your copy of the Bill of Lading, signed by the carrier, is your proof of the engine return.
