Installing

• For the correct tightening specifications, refer to => [ Oil Pan Overview ] Oil Pan Overview

• Silicone sealant, refer to the electronic parts catalog ETKA.

• Note the expiration date of the silicone sealant.

• The oil pan must be installed within 5 minutes after application of silicone sealant.

- Remove sealant residue from cylinder block with a flat scraper.

Wear safety glasses.

- Remove residual sealant on the oil pan for example with a rotating plastic brush.






- Clean sealing surfaces, must be free of oil and grease.

- Cut the tube nozzle at the front marking (nozzle diameter: approximately 3 mm).






- Apply silicone sealing compound bead as illustrated to clean sealing surface of oil pan.






• Thickness of sealant bead: 2 to 3 mm.

• The oil pan must be installed within 5 minutes after application of silicon sealant.

• The sealant bead may not be thicker than specified, otherwise excess sealant could enter the oil pan and clog the oil intake tube.

• Apply a bead of sealant at the rear area of the sealing flange very carefully - arrows in the illustration -.

- Immediately position oil pan in place and tighten bolts, tightening sequence. Refer to => [ Oil Pan Tightening Sequence ] Oil Pan Overview.

• When installing the oil pan to a removed engine, make sure that the oil pan is positioned flush with the cylinder block on the flywheel side.

• After installing oil pan, allow sealant to dry for approximately 30 minutes. Only after then may the engine oil be replenished.

- Add engine oil and check oil level.

Further assembly is performed in the reverse order of removal, thereby observing the following:
