Installation
Install cooling fan assembly and tighten bolts/nuts to the
specified torque.
Torque : 22 Nꞏm (2.2 Kgꞏm/16 lb ft) for fan pulley
and fan bracket.
Torque : 10 Nꞏm (1.0 Kgꞏm/88.5 lb in) for fan and
clutch assembly.
NOTE: Fan belts for 6VE1 Gasoline Engine mounted on
98MY (UX) have been brought into one. As a result, the
rotating direction of a fan belt is opposite to the direction
o f c o o l i n g f a n f o r 9 2 t o 9 7 M Y 6 V D 1 w i t h n o
interchangeability.
Therefore, incorrect installation of a fan may cause the air
for cooling to flow in the opposite direction, this resulting
in the poor performance of the air-conditioner and a rise
temperature in engine cooling water.
