SERVICE INFORMATION ON NEW DESIGN UPPER ENGINE MOUNT ASSEMBLY

APPLICATION

Model: 1992-96 Saturns

Group/Seq. No.: Chassis - 07

Corp. No. 686101

Bulletin No.: 96-T-48

Date: August, 1996

PURPOSE

This bulletin contains information on a new second design upper engine mount assembly. All 1996 Saturns built after and including VIN TZ371463 are built with a second design upper engine mount assembly (P/N 21012864). This second design upper engine mount assembly requires new, shorter engine mount assembly front cover studs (P/N 21007585). These new studs are 6 mm shorter than the old studs.

The second design upper engine mount assembly (P/N 21012864) should be used on 1996 vehicles built after and including VIN TZ371463 and 1997 vehicles.

Continue to use the first design upper engine mount assembly (P/N 21012185) on all 1992-95 vehicles, and 1996 vehicles built before and including VIN TZ371462. Once stock in the first design upper engine mount assembly (P/N 21012185) is depleted, the second design upper engine mount assembly (P/N 21012864) can be installed on vehicles built after the VIN breakpoint.

To use the second design upper engine mount assembly on vehicles built before and including VIN TZ371462, the old, longer upper engine mount assembly front cover studs must be replaced with the new, shorter engine mount assembly front cover studs.

NOTE: The following procedure should be used for installation of both new and old upper engine mount assembly front cover studs. The installation procedure for the upper engine mount assembly front cover studs, in the "Powertrain Mounts" section of the 1991-94, 1995, 1996 and 1997 "Chassis Service Manuals" is incorrect.

PROCEDURE

Remove the upper engine mount assembly front cover studs. See Fig 1 .

Fig 1: Upper Engine Mount Assembly Front Cover Stud Locations
If reinstalling existing upper engine mount assembly front cover studs, thoroughly clean thread locker from all threads, using a wire brush or wire wheel. Use Saturn Choke Aerosol Cleaner (P/N 21007127) or Saturn Brake and Choke Cleaner (P/N 21007432), or equivalent, to remove any remaining torque retention compound.
CAUTION: Protect yourself by wearing safety glasses when performing this procedure.
Thoroughly clean the upper engine mount assembly front cover stud holes using a 10 mm x 1.5 tap. Use compressed air to remove particles from the holes.
NOTE: To prevent damage to the front cover when upper engine mount assembly front cover studs are installed, DO NOT over apply Loctite 242 Thread Locker or equivalent; DO NOT allow Loctite Thread Locker or equivalent to accumulate in the bottoms of the stud holds.
Apply Loctite 242 Thread Locker (P/N 21485277) or equivalent to six to eight middle threads of the upper engine mount assembly front cover studs.
Install upper engine mount assembly front cover studs into engine front cover. Torque: 25 N.m (18 ft-lb).
