Detlection Method:
Apply a force ol 98 N (1 0 ksl, 22 lbl) and measure the
deflection between the alternator and the crankshaft
DUllev,
Defloction: 9- 11 mm (O.35-O.43 inl
NOTE: On a brand-new belt (one that has been run
for less than five minutes), the deflection should be
81881, Bl8Cl engine: 6 - 8 mm (0.23 - 0.32 inl,
818C5 engine: 7 - I mm (0.28 - 0.35 in) when first
measured, lf the belt is worn or damaged, replace it.

lf adiustment is necessary:
1. Loosen the alternator adjusting nut and mounting
nut.
2.
3.
Move the alternator to obtain the proper belt tension,
then retighten the adiusting nut and mounting nut
to the specified torques.
Recheck the dellection of the belt.
NOTE: lI necessary, adjust the P/S pump belt (see
section 17) and A/C compressor belt (see section
221.
Belt Tension Gauge Method:
Following the gauge manulacturer's instructions, attach
the belt tension gauge to the belt and measure the
tension.
Tension: 340-490 N {35-50 kgf,77-11O lbf)
NOTE: On a brand-new belt (one that has been run
for less than five minutes), tension should be
818B1, 818C1 engine: 690 - 880 N (70 - 90 kgf, 154 -
198 lbf), 818C5 engine: 540 - 740 N (55 - 75 kgf,
121 - 165 lbf) when first measured. lf the belt is
worn or damaged, replace it.
lf adiustment is necessary:
1. Loosen the alternator adjusting nut and mounting
nut.
2.
3.
Move the alternator to obtain the proper belt tension,
then retighten the adjusting nut and mounting nut
to the specified torques.
Recheck the tension ot the belt.
NOTE: It necessary, adjust the P/S pump belt (see
section 17) and A/C compressor belt (see section
22t.

Fan Motor Test
Disconnect the 2P connector from the fan motor.
Test the motor by connecting battery power to the
B terminal, and ground to the A termlnal.
lf the fan motor fails to run smoothly, replace it.
NOTE: The illustration shows the radiator fan.
Radiator Fan Switch Test
NOTE: Bleed air from the cooling system after installing
the radiator fan switch (see section 10)
1. Remove the radiator fan switch from the thermostat
housing.
2. Suspend the radiator fan switch in a container ol
coolanl as shown.
Heat the coolant and check engine coolant tempera
ture with a thermometer.
