Fan and alternator belt
The belt (1) that drives the cooling fan and alternator is
located at the front of the engine.
When you apply 98 N (22 lb) of pressure midway be-
tween the belt pulleys, a correctly tightened belt will de-
ect 10 – 15 mm (0.4 – 0.6 in) .at point (A).
If the fan belt is slipping, fan efîš¿ciency is lowered, re-
sulting in the engine running too hot, or the alternator
not charging. If the belt is too tight, the life of the alter-
nator bearing will be shortened. If the fan belt shows
signs of cracking or fraying, install a new one.
