HEATER & COOLING UNIT ASSEMBLY

9. Remove steering member.
10. Remove heater & cooling unit.
CAUTION:
Cap or wrap the joint of the pipe with suitable material such as vinyl tape to avoid the entry of air.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:

Replace the O-ring of the low-pressure flexible hose and the high-pressure pipe with a new one,
and then apply compressor oil to it when installing it.

When recharging refrigerant, check for leaks.
NOTE:
When filling radiator with coolant, refer to CO-9, "
Changing Engine Coolant" for QR engine or CO-31, "Chang-
ing Engine Coolant" for YD engine.

Inspection
Clutch disc
If the contact surface shows signs of damage due to excessive heat,
replace clutch disc and pulley.
Pulley
Check the appearance of the pulley assembly. If contact surface of
pulley shows signs of excessive grooving, replace clutch disc and
pulley. The contact surfaces of the pulley assembly should be
cleaned with a suitable solvent before reinstallation.
Coil
Check coil for loose connection or cracked insulation.
INSTALLATION
With Gasoline Engine (CWV-615M Compressor)
1. Install field coil.
Be sure to align the coil's pin with the hole in the compressor’s
front head.
2. Install field coil harness clip using a screwdriver.
3. Install pulley assembly using installer and a hand press, and
then install snap ring using snap ring pliers.

4. Install clutch disc on drive shaft, together with original shim(s).
Press clutch disc down by hand.
5. Using the holder to prevent clutch disc rotation.
After tightening the bolt, check that the pulley rotates smoothly.
6. Check clearance around the entire periphery of clutch disc.
If the specified clearance is not obtained, replace adjusting
spacer and readjust.
With Diesel Engine (DKV-11G Compressor)
1. Install field coil.
Be sure to align the coil’s pin with the hole in the compressor’s
front head.
2. Install field coil harness clip using a screwdriver.
