GENERAL INFORMATION

At the cycle of cooling working normally, the pressure shown by manometers in a collector should be 21–28 psi from low pressure and 206–213 psi from a high pressure.

The entrance temperature should be in limits 30–35°C with the engine working with frequency of rotation of a cranked shaft 2000–1, at high frequency of rotation of the fan.

Diagnostics

Symptom
Probable cause
Elimination method
Indications of manometers
Values of pressure on the high and low parties of pressure too low.
Air on an exit is slightly cooled.
Leakage of a coolant. Check and execute repair.
Add a coolant.
8
Values of pressure on the high and low parties of pressure too high. Defects in cooling or condenser freezing.
Proskalzyvaniye of a belt.
Support demanded level of a cooler. Clear the condenser.
Adjust a belt tension.
9
Values of pressure on the high and low parties of pressure.
Tube of low pressure not the cold.
Air in system. Clear or repair the receiver / dryer.
Check oil on pollution.
10
On the party with low pressure – negative pressure, and on the party with a high pressure – low pressure.
Drizzle or hoarfrost on tubes connected to the broad valve and the receiver / dryer.
Dust or the moisture which has frozen in the broad valve.
Leakage of a coolant.
Repair the receiver / dryer and replace the broad valve.
11
On the party with low pressure sometimes normal pressure passes to negative pressure. The moisture which has frozen in the broad valve. Repair the receiver / dryer.
12
Values of pressure on the high and low parties of pressure too high.
Drizzle or hoarfrost on tubes of the party of low pressure.
The broad valve is faulty.
It is faulty the receiver / dryer.
Repair the receiver / dryer.
Check oil on pollution.
13
On the party with low pressure – pressure high, and on the party with a high pressure – pressure low. Leak in the conditioner compressor. Replace the conditioner compressor.
