wºNew beltº refer to a belt which has been used less
than
5 minutes on a running engine.
wºUsed beltº refer to a belt which has been used on a
running engine for 5 minutes or more.
wAfter installing the drive belt, check that it fits properly
i n the ribbed grooves.
4. START ENGINE
5. TURN ON A/C SWITCH
Check that the A/C operates at each position of the blower
switch.
6. CHECK MAGNETIC CLUTCH OPERATION
If magnetic clutch does not engage, check the A/C fuse.
7. CHECK THAT IDLE INCREASES
When the magnetic clutch engages, engine revolution
should increase.

ON±VEHICLE INSPECTION
1. CHECK CONDENSER FINS FOR BLOCKAGE OR
DAMAGE
If the fins are clogged, clean them with pressurized water.
NOTICE: Be careful not to damage the fins.
2. MAKE SURE THAT DRIVE BELT IS INSTALLED
CORRECTLY
Check that the drive belt tits properly in the ribbed
grooves.
3. CHECK DRIVE BELT TENSION
Using a belt tension gauge, check the drive belt tension.
