Condition/Concern:

This is to announce a temporary program for the 2007 and 2008 Corvette Z06 with major engine failures.

In the past this engine has been on restriction and it was being exchanged as a complete assembly.

Recommendation/Instructions:

In an effort to gain product knowledge quicker Chevrolet is introducing a new program if a major engine failure occurs. Chevrolet would like to provide the opportunity for the customer to allow their Corvette Z06 to be picked up by special carrier and returned to the Bowling Green Assembly plant to have the engine exchanged.

If the customer agrees, General Motors will arrange to have a complete engine sent directly to the assembly plant. A specialized repair crew will exchange the engine, complete a diagnostic review, ensure the all codes are cleared and run the vehicle through the final assembly check. Once completed, the vehicle will be returned to the dealership on the first available carrier. Bowling Green Assembly anticipates the entire process should be completed in approximately 10 working days.

The process will include:

  1. Technician to verify an engine exchange is required. The Technician should follow the proper oil checking procedure and record the amount of oil that is in the engine. If the engine is not able to be started and properly warmed the technician should not add or drain any oil. If the oil level was changed the technician should accurately record the amount of oil that was in the engine prior to adding and the amount that was added.
  2. Contact the PQC (866-654-7654) to discuss an engine exchange.
