The Scanner Vehicle identification (ID) process prompts to you enter VIN characters and answer questions about the Vehicle to be tested. For some vehicles, the Scanner may display two or more engine choices. Be sure to scroll to confirm the number of engine choices. The engine number is stamped on the engine block or cylinder head, however, the exact location varies and is often difficult to see on an installed engine. For example, the number is often behind the water pump on V8 129 and 140 models, there may be multiple engine selections that are seen by scrolling after selecting the year. Typically, multiple engine choices apply to other markets and only one engine is used on North American vehicles for any given 3-1 provides some helpful tips for selecting the correct 3-1 VIN selections for North American vehicles (sheet 1 of 2)VINE ngine SelectionVIN used on 1995 models used on 1996 2000 modelsVIN used on 1995 models used on 1996 98 modelsVIN used on 1993 models used on 1994 models onlyVIN used on 1995 models used on 1996 98 modelsVIN used on 1995 models used on 1996 98 modelsVIN used on 1995 models not used on 1995 modelsVIN used on 1995 models used on 1996 98 modelsVIN used on 1995 models not used on 1995 US modelsVIN EA30 (1988 92) not used in used in USVIN not used in US ( ) used in US ( )
