Fig 17: Using Rotating Plastic Brush To Remove Remaining Sealant From Oil Pan (Upper Part) And At Cylinder Block
- Using rotating plastic brush, remove any remaining sealant from oil pan (upper part) and at cylinder block.
- Clean sealing surfaces, they must be free of oil and grease.
- Cut off nozzle on tube of sealant at front mark (dia. of nozzle approx. 1 mm).
- Insert new seals - 1 to 4 - into grooves on cylinder block.
- Apply sealant beads - arrows - to clean sealing surface of cylinder block as depicted in illustration.
- Thickness of sealant bead: 1.5 to 2.0 mm.
NOTE:
- The oil pan (upper part) must be installed within 5 minutes after application of sealant.
- Sealant bead must not be thicker than specified, otherwise sealant could get into oil pan and clog the strainer on intake tube.
- With a second technician, position upper section of oil pan and pre-tighten screws - 1 to 7 - to 5 Nm in diagonal sequence.
- Tighten bolts - 1 to 7 - diagonally to 15 Nm.
