WARNING! 
     
Do not re-use any fasteners that are worn or 
deformed in normal use. 
     Some fasteners are designed to be used only 
once, and are unreliable and may fail if used 
again. This includes, but is not limited to, 
nuts, bolts, washers, circlips and cotter pins. 
Always follow the recommendations in this 
manual-replace these fasteners with new 
parts where indicated, and any other time it 
is deemed necessary by inspection. 
     
CAUTION! 
     If large quantities of metal particles or other 
deposits (caused, i.e. by partial seizure of the 
crankshaft or connecting rod bearings) are 
found in engine oil, thoroughly clean oil 
passages and replace oil cooler to prevent 
damage from re-occuring. 
     Do not overfill with oil past the MAX mark on 
the oil dipstick. Damage to the Three Way 
Catalytic Converter (TWC) could result.

Installing  
      Installation is the reverse of removal, noting the 
following:  
     
-  Clean sealing surfaces so they are completely 
free of any oil or grease. 
     
WARNING! 
     
Wear protective glasses. 
    
Note:  
After applying silicon sealant D 454 300 2, oil pan must be installed within 
5 minutes.  -  Using rotating plastic brush, remove any remaining sealant from oil 
pan. 
    
Note:  
Sealant must not be thicker than 3 mm, otherwise excess sealant may get 
into the oil pan and clog the oil intake strainer.  -  Cut tube jet at front marking (jet diameter approx. 3 mm).
   Thickness of sealant: 2-3 mm (0.04-0.12 in.)
