Vauxhall/Opel Engine Codes

To help our customers understand some of the engine terminology we use, here is a list of the most common engine codes that we use to help identify your vehicle's engine when searching for products. You will find the engine designation on the engine block in front of the 8 digit engine number and often there is a sticker located on the engine.
