Important identification note
General Motors engine codes can cover multiple variations. GM-era Opel, Vauxhall, Saab and Holden are historical ownership associations; not every engine was engineered by GM. A directory entry does not guarantee fitment, interchange, OEM sourcing, available stock, or a quoted price. Verify OEM numbers and VIN before ordering.
