Engine rear cover (lower) installation note

Caution

• Be aware of the following points to assure the sealing performance of the engine rear cover (lower).

― Install the engine rear cover (lower) while verifying that the engine rear cover (lower) gasket is inserted into the groove of the engine rear cover (lower).

― Completely remove any oil, dirt, and sealant on the seal surface.

• To prevent silicone sealant from hardening, seal the engine rear cover (lower) to the cylinder head or cylinder block firmly within 10 min after applying silicone sealant. After sealing, complete the installation bolt tightening immediately.

• If oil, dirt, and sealant remain on the silicone sealant application surface and the step bead, the silicone sealant will not seal which will cause oil leakage.
