Oil Pan Installation Note

Completely clean and remove any oil, dirt, sealant or other foreign matter that may be adhering to the cylinder block and oil pan.
When reusing the oil pan installation bolts, clean any old sealant from the bolts.
CAUTION:
- Apply the silicone sealant in a single, unbroken line around the whole perimeter.
- To prevent silicone sealant from hardening, adhere the oil pan to the cylinder block within 10 min after silicone sealant is applied. Tighten the installation bolts completely soon after adhering.
- Using bolts with the old silicone sealant adhering could cause cracks in the cylinder block.
