EXCHANGE PROGRAM
An engine exchange program is now in effect to gain needed product feedback on the 1994 model year 2.2L (LN2) engine. The exchange program covers vehicles under warranty and will continue through the end of the 1994 model year. The engine exchange program is administrated by technical assistance.
SERVICE INFORMATION:
All requirements qualifying for engine exchange, warranty claims, processing procedures and shipping instructions are explained below. Your cooperation in following these procedures will greatly improve the effectiveness of the program.
A. Engine Exchange Guidelines
Conditions normally requiring partial engine replacement, a block or block components are indicated by the following symptoms:
1. Knock noises deep in the engine (i.e., crankshaft or rod bearing, piston or piston pin).
2. Seized engine (i.e., engine is locked and will not turn over with spark plugs removed).
3. Low or no cylinder compression.
4. Excessive oil consumption.
5. Hydraulic lock.
6. Crack or porosity in cylinder block.
7. Coolant in oil, and/or bubbles in surge tank.
8. Conditions of excessive chain rattle noticed inside the car with the engine running at idle speed.
9. Valve train noise conditions requiring cylinder head removal.
B. Exchange Procedure
Once the above preliminary diagnosis is made and an exchange unit is deemed necessary, call your technical assistance.
- Technical assistance will require the VIN and engine serial number. (The engine serial number can be read from a boss on the block at the head face, exhaust side near the transmission bell housing. The number begins with the letter "T" and is followed by four numbers and three additional letters.)
- Technical assistance will also require a street shipping address and not a post office box. Addresses with post office boxes will not be used.
- Technical assistance will arrange to ship a replacement engine within 48 hours. The replacement engine will be complete except for starter, accessory drive components and brackets.
- A technical assistance case number will be provided for each engine exchange. This number must be recorded on the identification card supplied with the replacement engine and must be affixed to the engine being returned. The identification card must be fully completed.
- To avoid a charge back, the exchange unit must be returned to Tonawanda within 10 days in the original shipping crate. Failure to return the concerned unit will result in the DEALERSHIP being billed the value of an exchange unit.
- The exchange unit must be complete as removed from the vehicle. Dealerships returning incomplete units risk being billed for missing materials. All procedural steps must be followed to ensure the dealership is not billed for an 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 above. Dealerships returning units 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.
Attached to the exchange unit will be a return shipping label (freight is prepaid).
C. Preparation for Shipping
Visually check all fluid levels to assure they are within the normal operating range. If not, drain and measure the oil and coolant from the concerned unit. Record the oil and coolant measurement results on the repair order. REPLACE THE DRAIN PLUG.
Remove the engine assembly as outlined in the 1994 service manual. Remove all plastic shipping plugs and covers from the exchange unit and install them on the removed unit.
If engine leaks, mark leak area on engine.
Place the removed unit into the original shipping container. Include a copy of the repair order in the original envelope and attach to the removed engine. Write the technical assistance reference number on the repair order.
D. Shipping Instructions
Place the return shipping label over the original container shipping label.
The Bill of Lading and Customs Papers (when necessary) provided with the exchange engine are the only documents required to return ship the removed engine.
NOTE:
The same carrier, whose name Is Indicated on the Bill of Lading, should be used for the return engine shipment.
All required data on the Bill of Lading will be complete except the date and carrier signature. 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 returning the engine.
The returned engine is to be shipped by truck freight collect to:
GM Powertrain
Tonawanda Engine Plant
River Road
Tonawanda, NY 14150
ATTN: Engine Exchange Program 2.2L
Warranty Room - Plant 1
To increase the effectiveness of the program, the removed unit should be returned IMMEDIATELY. Failure to return the removed unit will result in the dealership being billed $2,047.50 for the unit furnished, plus an administrative charge.
E. Warranty Claims Processing Procedure
Upon completion of the repair, a warranty claim is to be submitted to the marketing division.
NOTE:
Applicable miscellaneous items, such as engine oil and engine coolant, should be added to the above Part Allowance amount and included in the Net Amount (DMN) column of the claim.
YOUR COOPERATION IS GREATLY APPRECIATED. PROMPT RETURN OF YOUR CONCERNED UNIT WILL INCREASE THE EFFECTIVENESS OF THIS PROGRAM. IF YOU HAVE ANY QUESTIONS CONCERNING THE EXCHANGE PROGRAM ADMINISTRATIVE PROCEDURES, PLEASE CONTACT TECHNICAL ASSISTANCE.
