Driver Side Engine Mount – ACDelco (85579398)

Driver Side Engine Mount mounts and isolates a heavy powertrain component. Hydraulic-filled and solid designs are not interchangeable even when the bolt pattern matches.

Replace the Side Engine Mount when there is excessive movement under load or a vibration that was not there before. A collapsed mount loads the others and they fail in sequence.

This Side Engine Mount is listed under part number 85579398, filed under Engine Mounts & Covers. If the original number is unreadable, send us the VIN and we will confirm the reference before dispatch.

This is ACDELCO dealer-sourced stock rather than an equivalent, so the number on the Side Engine Mount traces straight back to the manufacturer.

This listing is specifically for the driver (left-hand) side; the opposite side is a separate part number.
