Driver Side Engine Mount is a compliant mounting element that holds a drivetrain component in place while absorbing movement. The bonded rubber fails from heat and oil long before the metal does.
Replace the Side Engine Mount when the bonded rubber is cracked, when fluid has leaked from a hydraulic mount, or when vibration at idle has increased. Check the other mounts before deciding how many to change.
The Side Engine Mount in this listing carries part number 85579396 and sits in the Engine Mounts & Covers category. The number stamped on the original part is the only reliable cross-reference.
This is GM dealer-sourced stock rather than an equivalent, so the number on the Side Engine Mount traces straight back to the manufacturer.
Position matters here: this is the driver (left-hand) unit, and fitting it to the other side will not work.
