1. Examine the blower fan for wear spots, cracked
blades, a cracked hub, a loose fan retaining nuts,
or bad alignment.
2. Examine the blower case for sports.
Did you find any problem?
Repair as required.
Is the repair complete?
Replace the motor and fan assembly.

If the noise is a click/tick or whine, replace the motor.
Is the repair complete?
Reinstall the original motor.
Is the problem still present?
1. Set the blower speed on 4.
2. Check full hot to full cold temperature positions in
the defroster, floor, and vent modes.
Is the noise present in the defrost mode only?
1. Check the ducts for obstructions for foreign
materials.
2. Remove any obstructions or foreign materials.
3. Check floor /defroster door seals.

DIAGNOSIS USING THE MANIFOLD GAUGE
On normal operation during the cooling cycle, the
manifold gauge must indicate approximately 1.5 - 2.0
kg/cm
2 at low pressure side and 14.5 - 15 kg/cm2 at
high pressure side, on condition that the temperature
at the cooler inlet, 30 ºC - 35 ºC, 2,000 rpm of the
engine rpm , full cold and maximum blower speed.
Cause Symptom
Action
1. High and low pressure are abnormally low.
2. Air at cooler outlet is not cold.
1. High and low pressure are abnormally high.
1. High and low pressure are abnormally high.
2. Connection at the low pressure is not cold.
There is a gas leak in the
cooling system.
Insufficient cooling and
faulty condenser cooling
by excessive
refrigerant.
Belt is slipped
There is an air in the
cooling system
Check the oil leak,
repair
Add the refrigerant
Keep the specified
amount of the
refrigerant, Clean the
condenser
Repair the belt
Clean and repair the
receiver-drier
Check the oil
contamination etc.

Operation Check
Notice: Operation Check is recommended before
removing the manifold gauge.
1. Install the manifold gauge set.
2. Run the engine at 2,000 rpm and set the blower
switch at ‘HI’ and A/C switch ‘ON’. Set the
temperature control lever at ‘COOL’.
3. Keep opening all of the window and door.
4. Place a dry bulb thermometer to the front duct.
5. Place a psychrometer close to the inlet of the
cooling unit.
6. Check the high pressure gauge reading within
14 - 16 kg/cm
2
If the reading indicates high excessively, spray
the water to the condenser.
If the reading indicates low excessively, cover the
condenser with the towel.
7. Check the temperature of air inlet within 25 - 35 °C.
8. Calculate the relative humidity from the
psychrometic graph comparing the wet/dry
temperature at the air inlet.
9. Measure the wet/dry temperature at the cold air
outlet and calculate the temperature difference of
the dry bulb between the inlet and the outlet.
10. Check the cross point of the relative humidity and
check the temperature difference between the
black line. If the cross point is located between
the black line, the cooling performance is normal.
4. The discharging pressure increases when the
charging valve charges excessively, so charge
the charging valve to the specified amount with
measuring the weight of the refrigerant before
closing the high pressure valve.
5. Charge the specified amount of the refrigerant and
then close the valve of the manifold gauge. Check
the system for any leak.

Total Oil Capacity 265 cc
COMPRESSOR OIL
REPLACEMENT
Before Oil Replacement
When any part is replaced or there are a lot of gas
leaks in the A/C system, you should add the specified
amount of the oil to keep the approval oil capacity
because the oil for lubricating the compressor
circulates through the A/C system during operating
the compressor.
Handling Oil
Be careful that moistures, dusts etc. must not flow
into the oil.
Do not mix with any other material.
If the oil leaves outside for long time, it’s possible
to mix it with the moistures and so keep the oil
sealed with a container.
Circulating Oil
For checking or adjusting the oil level, set the control
unit to full cold and max blower speed with keeping
the engine run at idle for 20 - 30 minutes in order to
circulate the oil through the compressor.

Water Sensor
Water sensor is a thermistor that detects engine coolant
temperature to operate the blower speed to LO when
water temperature is less than 50.
1. Check that there are water sensor fault code (15,16)
by using self-diagnosis function.
2. Disconnect water sensor 2-pin connector that
installed on the heater unit of inner instrument panel
and remove the water sensor.
3. Check that measured resistance value among
water sensor terminals is as shown in the right
side graph.
Notice: Measure resistance value by soaking the
sensor in the ice water and check changes in
resistance values after soaking it in the very hot
water.
4. If resistance value is out of specification, replace
the water sensor.
5. Install the sensor and turn the ignition switch to
ON position and check that voltage between No.
7a terminal of the water sensor and body (-) is 5V.
6. Check current between the No. 7a and 7b connector
terminals of the water sensor and the No. 3 and 5
connector terminals of the airconditioner control unit
and repair the wire if defective.
