The installed engine type is part of the Line, Body, and Engine type three character code found in serial number positions 4, 5 and 6. This three character code represents the basic body (or platform) type, and engine type installed for each particular model year. Sometimes this code will remain the same from one year to another although the installed engine type could change. Although the code describes which engine type is installed as original equipment for a particular model year, this code is not a portion of the five character engine type and serial number stamped on the engine block. The engine type and serial number are found near the front of the vehicle, stamped on the engine block where the transaxle housing and engine block join one another.
The engine type is a five character code, which is followed by and separated from the engine serial number by a hyphen. This code is used the by the manufacturer to designate the engine type. Locate the engine code stamped in the engine block and determine the engine type before attempting to service the vehicle. Write down and keep handy the engine code and the engine type along with the complete VIN number of the vehicle. Knowing the engine type and vehicle serial number will not only help with obtaining the correct service information, this information will assist the local parts vendors when shopping for replacement parts. Bring the manual along when shopping for parts. Having the manual handy could help to properly identify a needed part. If a part has to be ordered, it's far better to order it correctly the first time and/or avoid having a vehicle completely disassembled only to find out the part needed is not in stock. On rare occasions, a part may be back-ordered, meaning the part is temporarily unavailable. In a situation such as this, it may be wise to wait until the part is available before starting on the repair or maintenance about to be undertaken, if the vehicle can be operated in a safe and reliable manner.
