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.
Reference number for the Side Engine Mount: 85579394. It is filed under Engine Mounts & Covers, and it is the number that has to match the part coming off the vehicle.
Genuine GM supplied for this Side Engine Mount, with the engineering number unchanged from the factory reference stamped on the original.
Position matters here: this is the driver (left-hand) unit, and fitting it to the other side will not work.
