Attention.
- Make sure the drive belt is properly installed in the pulley grooves.
- Check to see if any oil or coolant has come into contact with the drive belt and pulleys.
- Using a brush, remove all dirt from the pulley grooves.
- Some drive belts have five guide gussets, while the air conditioning compressor pulley, power steering pump pulley and alternator pulley have six grooves. In this case, it is necessary to check that the inner groove of the pulleys (O) remains free.
2. Release the auto tensioner and tighten the drive belt.
3. Turn the crankshaft pulley clockwise several times to equalize the belt tension between the pulleys.
