RTV Application and Component Installation

NOTE: Only the Saturn recommended RTV (Saturn P/N 21006236 or equivalent) should be used. Surfaces to be sealed must be clean and dry.





1. Cut tube opening to approximately 2.0 mm (.080 inch) inner diameter. Apply the following RTV bead sizes to clean surfaces: Oil Pan: 4.0 mm (0.160 inch) Front Cover: 2.0 mm (0.080 inch) Rear Seal Carrier: 2.0 mm (0.080 inch) Cam Cover: 2.0 mm (0.080 inch)
a. T-joints.
b. When replacing procured gasket. Follow each surface pattern and maintain the bead diameter cross sections required to ensure the joint is sealed.





NOTE: 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.





NOTE: The front cover oil seal drainback 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 engines require a RTV bead around the top, center bolt hole.

4. Front cover. 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 inch drill and tap handle. The front cover non tapped holes can be cleaned with a 3/8 inch drill.

CAUTION: To prevent engine front cover and mount damage, the three Font 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.





7. Cam/rocker cover:
a. The cover seal groove must be dean and dry. Apply a 2.0 mm (0.080 inch) bead of RTV in the center of the casting groove.
b. Remove the procured gasket from the package, and press the flat side of the gasket firmly into cam/rocker cover groove while RTV is still wet (within ten minutes). Install the cover immediately.

CAUTION: If the cover is not installed immediately, it must be placed on a flat surface with the sealing surface (gasket) downward. This ensures the wet RTV bonds properly with the procured gasket.
