RTV Application and Component Installation

IMPORTANT: Only the Saturn recommended RTV should be used. Surfaces to be sealed must be clean and dry.






1. Cut tube opening to approximately 2.0 mm (.080 in.) inner diameter.





Apply the following RTV bead sizes to clean surfaces:
- Oil Pan: 4.0 mm (0.160 in.)
- Front Cover: 2.0 mm (0.080 in.)
- Rear Seal Carrier: 2.0 mm (0.080 in.)
- Cam Cover: 2.0 mm (0.080 in.)

a. T- joints.
b. When replacing precured gasket.





Follow each surface pattern and maintain the bead diameter cross sections required to ensure the joint is sealed.

IMPORTANT: Apply bead on the inside edge of the groove as shown.

2. Oil pan.





3. Make sure oil pump transfer port seals and front vibration damper/pulley seal are installed correctly.






IMPORTANT:
- The front cover oil seal drain-back hole and passage way must be kept free of RTV to prevent front seal damage. After the front cover is installed, 6-12 squirts of oil can be pumped through the front oil seal drain back hole to make sure it is not plugged.
- Extra RTV is required at oil pan, cylinder head and cam/rocker cover T-joints to make sure gaps are filled to prevent oil leakage. The 1992 and later engines require a RTV bead around the top, center bolt hole.

4. Front cover.

IMPORTANT:
- Install a thin film of RTV sealant between the vibration damper/pulley assembly flange and washer only. The washer and bolt head flange are designed to prevent oil leakage and do not require sealant.
- The front cover, cylinder head and block holes must be cleaned with a 3/16 in. drill and tap handle. The front cover non tapped holes can be cleaned with a 3/8 in. drill.

NOTICE: To prevent engine front cover and mount damage, the three front upper mount to engine front cover nuts must be tightened down uniformly.






5. Install the two mount to midrail bracket nuts first. Next, install the three front upper mount to engine front cover nuts. Remove the block of wood from under the torque strut after the upper mount assembly is installed.

Upper Mount to Front Cover:
- Torque: 50 Nm (37 ft. lbs.)

Upper Mount to Frame Rail Bracket:
- Torque: 50 Nm (37 ft. lbs.)






6. Rear seal carrier.
