ON-VEHICLE INSPECTION
PROCEDURE
1. INSPECT REFRIGERANT PRESSURE WITH MANIFOLD GAUGE SET
(a) This is a method to specify trouble areas by using a manifold gauge set. Read the manifold gauge pressure when the following conditions are established.
Test conditions:
Gauge readings (Reference)
(1) When the refrigerant volume is proper: Gauge reading: Low pressure side: 150 to 250 kPa (1.5 to 2.5 kgf/cm2, 22 to 36 psi) High pressure side: 1370 to 1570 kPa (14.0 to 16.0 kgf/cm2, 199 to 228 psi) |
|
(2) When there is moisture in the refrigeration system:
Symptoms |
Probable Cause |
Diagnosis |
Corrective Actions |
---|---|---|---|
During operation, pressure on low pressure side cycles between normal and vacuum |
Moisture in refrigeration system freezes at expansion valve orifice, causing temporary stop of cycle. However, when melted, normal state restored |
|
|
(3) When cooling is insufficient:
Symptoms |
Probable Cause |
Diagnosis |
Corrective Actions |
---|---|---|---|
|
Gas leakage from refrigeration system |
|
|
(4) When the circulation of the refrigerant is poor:
Symptoms |
Probable Cause |
Diagnosis |
Corrective Action |
---|---|---|---|
|
Refrigerant flow obstructed by dirt in condenser |
Condenser clogged |
Replace condenser |
(5) When the refrigerant does not circulate:
Symptoms |
Probable Causes |
Diagnosis |
Corrective Actions |
---|---|---|---|
|
|
Refrigerant does not circulate |
|
(6) When the refrigerant is overcharged or cooling of condenser is insufficient:
Symptoms |
Probable Causes |
Diagnosis |
Corrective Actions |
---|---|---|---|
Pressure extremely high on both low and high pressure sides |
|
|
|
(7) When there is air in the refrigeration system:
Symptoms |
Probable Cause |
Diagnosis |
Corrective Actions |
---|---|---|---|
|
Air in refrigeration system |
|
|
(8) When the expansion valve malfunctions:
Symptoms |
Probable Cause |
Diagnosis |
Corrective Action |
---|---|---|---|
|
Trouble in expansion valve |
|
Replace expansion valve |
(9) When the compressor is defective:
Symptoms |
Probable Cause |
Diagnosis |
Corrective Action |
---|---|---|---|
|
Internal leakage in compressor |
|
Repair or replace compressor |
Cleaning and protecting the vehicle exterior
Perform the following to protect the vehicle and maintain it in prime condition.
● Working from top to bottom, liberally apply water to the vehicle body, wheel
wells and underside of the vehicle to remove any dirt and dust.
Wash the vehicle body using a sponge or soft cloth, such as a cham ...
