Pic. 6–4. The place where a layer of sealant with a diameter of 3 mm is applied to the mating surface of the oil pan
Apply a layer of sealant D176 404 A2 with a diameter of 3 mm to the mating surface of the oil pan (pic. 6–4).
After applying a layer of sealant, the oil pan must be installed within 5 minutes, allowed to dry for 30 minutes, and only then poured into the engine engine oil.
The sealant layer should be no more than 3 mm in diameter, as excess sealant can get into the oil and block the strainer.
Tighten the oil pan bolts evenly diagonally.
On engines with a gasket on the lower section of the oil pan, do not overtighten the bolts, otherwise the oil pan gasket will be deformed.
On engines in which the lower section of the oil pan is installed on the sealant, tighten the mounting bolts first to a torque of 5 Nm, then finally to a torque of 10 Nm.
Fill with coolant.
Pour into the engine engine oil.
