Before you order: GM part numbers change by option code and year. Confirm against your VIN with a GM dealer. Callout numbers on this page are our own and do not match GM's diagram numbers. Quantities are per vehicle (both sides).
Engine: most mounts, brackets and the brace are different for the 2.4L and the V6. Each row lists the number per engine. The drawing is a simplified, generic layout, not to scale.
