(Procedure)

①

Adjust the tension by gradually
loosening the fastening bolt of the
alternator.

②

Visually check if there are any cracks or
tears in the belt.

③

Loosen the fastening bolt of the
alternator until the play of the belt
reaches 10 to 15mm[98N(10kgf)] when
pushed by fingers, and adjust it.

④

Be careful not to leave any grease or
LLC on a belt while changing it. If any
such material is left, wipe it off
completely.

Check the water pump belt

(Procedure)

①

After loosening the nut fixing the tension pulley,

adjust the belt by moving the pulley with the
adjusting bolt.

②

While adjusting the belt tension, check it for

any crack or wear, and if any fault is found,
replace it.

③

Be careful not to leave any grease or LLC on a

belt while changing it. If any such material is
left, wipe it off completely.

Then check the deflection of
