Installation
1. CAUTION: In order to prevent foreign material from contaminating the engine block or the engine front cover it is necessary to seal the coolant and oil passages of both components. Failure to follow these directions will result in engine damage.
CAUTION: Do not use a surface conditioning pad or any other type of fibrous abrasive disc to clean the gasket surfaces. Failure to follow these directions will result in engine damage.
Clean and inspect the engine block and front cover as follows:
- Pack the exposed portion of the oil pan with clean shop towels.
- Plug the oil and coolant passages.
- Clean the gasket surfaces.
- Clean all surfaces requiring gasket sealant with metal surface cleaner.
- Using compressed air, remove any remaining foreign material from the engine block and engine front cover.
- Remove the shop towels from the oil pan.
- Remove the plugs or seals from the engine block and engine front cover.
2. NOTE: If the engine front cover is not secured within four minutes, the sealant must be removed and the sealing area cleaned with metal surface cleaner. Allow to dry until there is no sign of wetness, or four minutes, whichever is longer. Failure to follow this procedure can cause future oil leakage.
Apply a small amount of silicone gasket and sealant as shown.
