If a dirty or undrained core is received, you will be contacted, advised of the deficiency and remedial action will be taken on our part. We will absorb the cost to clean and/or drain the first non-compliant core received. You will also be advised as to requirement compliance for all future core returns.

Prepare Part(s) shipments to the dealers as follows:

Where applicable, the exchange unit shipping carton is to be reused when returning cores. Also, reuse the packing material to secure the core in the carton. 

Properly pack the part in either the original box or a suitable sized box. 

Wrap the part in protective packing material to restrict movement, and avoid damage to other parts, before placing into outer shipping container.

Do not combine heavy and light weight parts within the same box. Example: Transmission and phone; alternator and COMAND®. 

Ship Hazmat items according to government regulations. 

Carefully package all items to ensure they are not damaged by other parts. 

All fluids (oil, A/T fluid, fuel, P/S fluid) must be completely drained. 

Reinstall all packing plugs and caps if applicable (i.e., A/C Compressors, Engine, Transmissions, etc.). 

The exterior of the core must be completely cleaned. All heavy accumulation of oily dirt, grease and grime must be removed; use a degreaser, high pressure hot water hose, power washer or steam hose. Do not allow water to enter the core. 

All engine cores must have the water pump reinstalled and torqued to the block according to Service Specifications. The water pump is used as a lifting point during the unloading process at the factory. It is important to follow this requirement in order to prevent injury or damage. 

The engine core is to be secured in the shipping palletainer and, if available, reinstall the protective plastic bag supplied with the exchange unit. 

Note: MBUSA reserves the right to reject the core part return if the part(s) were not properly packaged according to the guidelines described above
