REMOVAL SERVICE POINTS
<> FLEXIBLE SUCTION HOSE AND
FLEXIBLE DISCHARGE HOSE
DISCONNECTION
CAUTION
As the compressor oil and receiver are highly
moisture absorbent, use a non-porous material
to plug the hose and nipples.
To prevent the entry of dust or other foreign bodies,
plug the dismantled hoses and compressor nipples.
<> DRIVE BELT REMOVAL <1300,
1600>
CAUTION
To reuse the drive belt, draw an arrow indicating
the rotating direction (clockwise) on the back of
the belt using chalk.
1. Loosen the power steering oil pump fixing bolts A,
B and C.
2. Turn the adjusting bolt D in the anti-clockwise
direction (to the left) to remove the drive belt.
<> DRIVE BELT REMOVAL <2000>
The following operations will be needed due to the
serpentine drive system with the alternator drive belt
auto tensioner.
1. Securely insert the spindle handle or ratchet
handle with a 12.7 mm insertion angle into the jig
hole of the alternator drive belt auto tensioner,
and turn the alternator drive belt auto tensioner
anti-clockwise until it hits the stopper.
CAUTION
To reuse the alternator drive belt, draw an arrow
indicating the rotating direction (clockwise) on
the back of the alternator drive belt using chalk.
2. Align hole A with hole B, insert an L-shaped
hexagon wrench, etc. to fix and then remove the
alternator drive belt.
<> COMPRESSOR REMOVAL
Take care not to spill any compressor oil when
removing the compressor.
