Installing

NOTE:

Note the expiration date of the silicone sealant.

The sealing flange must be installed within 5 minutes after application of the silicone sealant.

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

After installing the sealing flange, the sealant must dry for approximately 30 minutes. Only after then may the engine oil be added.

-- Remove any sealant residue on the cylinder block using a flat blade scraper.

WARNING:

Wear safety glasses.

-- Remove any remaining sealant on the sealing flange using, for example, a rotating plastic brush.
