Oil Pan: Service and Repair
Oil Pan
Special tools, testers and auxiliary items required
• Torque Wrench (5-50 Nm) (V.A.G 1331)
• Socket XZN 8 (T40159)
• Used Oil Collecting and Extracting Device (V.A.G 1782)
• Sealant (D 176 501 A1)
• Hand Drill with Plastic Brush Attachment
• Flat Scraper
• Protective Eyewear
Removing
- Remove the noise insulation.
- Disconnect the connector from the oil level thermal sensor (G266).
- Drain the engine oil.
• Always follow the regulations for disposing of old engine oil!
- Remove the oil pan bolts on the transmission side - arrows - using (T40159).
- Remove the oil pan to cylinder block bolts and then remove the oil pan.
- Loosen the oil pan with light blows from a rubber mallet if necessary.
- Remove sealant residue from the cylinder block with a flat scraper.
- Remove any sealant residue from the oil pan with a rotating brush, using a hand drill with a plastic brush attachment (wear eye protection).
- Clean the sealing surfaces, they must be free of oil and grease.
Installing
• Note the expiration date of the sealing compound.
• The oil pan must be installed within 5 minutes after application of silicone sealant.
- Cut the tube nozzle at the front mark (nozzle diameter approximately 3 mm).
- Apply silicone sealing compound (D 176 501 A1), as shown, to the clean oil pan sealing surface. The sealing compound bead must be:
• 2 to 3 mm thick
• and run on the inside of the bolt holes - arrows -
• Sealant bead must not be thicker than specified. Otherwise, excess the sealant could get into the oil pan and clog the strainer in suction pipe.
• After installing the oil pan, allow the sealant to dry for approximately 30 minutes. Only after then may the engine oil be added.
- Apply sealant (D 176 501 A1) to the clean sealing surface as shown.
- Install the oil pan immediately and tighten all oil pan bolts lightly.
- Hand tighten the oil pan to transmission bolts just enough so that the oil pan contacts the transmission.
• With the transmission removed, the oil pan must seal flush with cylinder block.
- Tighten the oil pan to cylinder block bolts to 11 Nm.
- Tighten the oil pan to transmission bolts to 45 Nm.
The rest of the installation is basically a reverse of the removal sequence.
