Installing
• For the correct tightening specifications, refer to => [ Oil Pan and Oil Pump Overview ] Engine
• Silicon sealant, refer to the Parts Catalog
• Note the expiration date of the silicone sealant.
• The upper oil pan must be installed within 5 minutes after the silicone sealant has been applied.
• Replace the bolts which are being tightened with an additional turn.
• Replace sealing rings, seals and self-locking nuts.

• Thickness of sealant bead: 2 to 3 mm
- Apply silicon sealant to clean sealing surfaces of the upper oil pan as shown in illustration - arrow -.
- Apply the silicon sealant, as shown in the illustration - arrows -, between the cylinder block and the lower timing chain guard.
• The upper oil pan must be installed within 5 minutes after application of silicone sealant.
• The sealant bead may not be thicker than specified, otherwise excess sealant could enter the oil pan and clog the oil intake tube.
• On the transmission side, the upper oil pan and the crankcase must align.
