Removing
1. Remove the lower engine mudguard.
2. Drain the engine oil by loosening the oil drain plug about half a turn. Place an oil drain container under the drain plug and unscrew the plug completely. If necessary, press down on the plug when unscrewing to prevent the oil from leaking prematurely.
3. When the oil has completely drained, screw the oil drain plug back into place.
4. Unscrew two or three bolts securing the oil pan to the gearbox housing.
5. Unscrew bolts and remove the oil pallet from the block of cylinders.
Oil drain plug tightening torques:
- 1.4-/1.6-I engines - 30 Nm
- engine 1.8-I - 40 Nm
- engine 2.3-I - 20 Nm
Installation
1. Using a plastic or wooden scraper, scrape the old gasket off the surface of the cylinder block that mates with the oil pan.
2. Using a rotating metal brush mounted on an electric drill, clean the sealant from the oil pan.
3. Apply a layer of sealant VW-D 176 404 A2 with a diameter of 3 mm to the mating surface of the oil pan (places of application of sealant are indicated by arrows).
Warning: After applying a layer of sealant to the oil pan, install the oil pan within 5 minutes. The drying time of the sealant is 30 minutes, and only after that can engine oil be poured into the engine.
Warning: The sealant layer should only be 3 mm in diameter, as in the case of a thick sealant layer, excess sealant will enter the oil and may block the strainer.
4. You can also apply a layer of sealant to the mating surface of the cylinder block (places of application of sealant are indicated by arrows).
5. Install the oil pan to the engine block and secure it with the bolts finger-tight.
6. Screw in the bolts securing the oil pan to the gearbox housing and tighten them to a torque of 40 Nm.
7. Tighten the oil pan bolts crosswise to 10 Nm, then tighten all bolts in the same sequence to 15 Nm.
8. Fill the engine with engine oil.
9. Install the lower engine compartment mudguard.
