Note:
The bead of sealant must not be thicker than 3
mm, as otherwise excess sealant may enter the
oil pan and block the strainer in the oil intake line.

Be particularly careful when applying the sealant around the rear sealing
flange -arrows in illustration-. - Make sure sealing surface is clean and then apply silicone sealant on
sealing surface of oil pan, as shown in illustration. (Illustration shows
position of sealant on cylinder block.)

pan to cylinder block to 5 Nm initially.

- Tighten bolts securing oil pan to cylinder block in diagonal sequence in
2 stages; tighten to 10 Nm when tightening second time.
