ENGLISH
Adjusting
1. Loosen the adjusting plate bolt and the
mounting bolt.
2. Insert a bar between the alternator and the
cylinder block to move the alternator to obtain
the required belt deflection.
3. Tighten the mounting bolt and the adjusting
bolt.
6.5 Every 1000 service hours
6.5.1 Check the starter
1. Check for visual defects.
2. Check to see if the pinion is shifted into mesh
with the flywheel ring gear when the starter is
energized. If the pinion does not shift properly,
consult your Mitsubishi dealer.
6.5.2 Check the alternator
1. Check for visual defects.
2. Remove the belt from the alternator. Turn the
pulley by hand to check the alternator for
smooth rotation. If the alternator fails to rotate
smoothly, consult your Mitsubishi dealer.
6.6 Every 2 years
6.6.1 Change coolant
Long Life Coolant (LLC) used in your engine
retains its efficiency for 2 years. Be sure to change
the coolant every 2 years.
6.6.2 Draining
1. Start and operate the engine until the coolant
temperature is 70°C to 80°C (158°F to 176°F).
Then stop the engine.
2. Remove the filIer cap only after the engine
has been stopped and the cap is cool enough
to remove with your bare hands.
CAUTION
• If the fan belt is too tight, excessive stress is
put on to the fan bearings and belt, which
might shorten the life of both. If it is too
loose, it will slap against the pulleys, causing
unnecessary wear and tear to the belt, which
could cause possible slipping, to the extent
that the engine will overheat.
• Keep the belt free from oil or grease.
