Removal
The engine is installed. Unscrew the air guide pipe bracket from the oil pan "arrows".
Remove the right air duct hose "2" from the intercooler. Ignore pos. "1".
Car since 05.2002.
Remove the oil level and temperature sensor "0266" "arrow".
All
Remove the toothed belt: toothed belt drive with hydraulically damped tension roller, toothed belt drive with friction-damped tension roller.
Remove the crankshaft timing belt sprocket, for this use the support key "3415".
Unscrew bolts "1...10". Lift the sealing flange and remove it. Press out the cuff with the sealing flange removed.
Installation
Install in reverse order, placing a rag on the open part of the oil pan. Carefully remove any remaining sealant on the cylinder block and oil pan. Remove any remaining sealant on the sealing flange, for example, using a drill with a plastic brush. Clean the sealing surfaces; there should be no traces of oil or grease on them. Cut off the tube tip at the front mark (hole diameter about 2mm). The sealant must be applied in several places on the engine, as follows. Apply a thin strip of sealant "arrows" to each adjacent surface between the cylinder block and the oil pan,
Apply a strip of sealant "arrow" to the clean sealing surface of the sealing flange, as shown in the figure. Thickness of the strip of sealant "arrow": 2-3 mm.
Instructions: The sealant strip should not be thicker than 3 mm, otherwise excess sealant may get into the oil pan and clog the mesh filter of the oil intake pipe.
Apply a thin layer of sealant to the lower sealing surface of the "hatched" sealing flange. The flange with the seal must be installed within 5 minutes after applying the sealant.
Carefully push the sealing flange onto the cylinder block centering bushings.
Tighten the bolts in the following sequence: bolts "1...6", then bolts "7...10". Install the crankshaft seal on the belt pulley side. Install the toothed belt (adjust valve timing): toothed belt drive with hydraulically damped tension roller, toothed belt drive with friction-damped tension roller. Install the poly V-belt.
Instructions. The hoses and hose nipple of the air boost system must be cleaned of oils and grease before installation. Do not use lubricants under any circumstances.
Install the air ducts into the clamps.
Tightening torques:
- Sealing flange to cylinder block: 15 Nm
- Air guide pipe to oil pan: 8 Nm
