Installation
All vehicles
1. CAUTION: Failure to back off the set screws can result in damage to the cylinder block cradle.
Back the set screws off until they are below the cylinder block cradle boss.
2. CAUTION: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to remove all traces of the old cylinder block cradle gasket and sealant.
NOTE: Gasket material as well as silicone sealant may be present in the cavities in the main bearing cap. This material must be removed completely prior to assembly.
Clean the gasket mating surfaces, making sure all the sealant is removed from the cavities on the rear main bearing cap. To clean the sealing area, use a plastic scraping tool, silicone gasket remover and metal surface prep. Follow the directions on the packaging.
3. NOTE: If not secured within 4 minutes, the sealant must be removed and the sealing area cleaned. To clean the sealing area, use silicone gasket remover and metal surface prep. Follow the directions on the packaging. Failure to follow this procedure can cause future oil leakage.
Apply silicone in the 6 places shown.
