THE GENERAL DATA

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

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

Diagnostics

Symptom
Plausible reason
Elimination method
Indications of manometres
Values of pressure on the high and low parties of pressure too low.
Air on an exit is slightly cooled.
Coolant leak. Check up 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.
Проскальзывание 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 / a dryer.
Check up 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 / a dryer.
Dust or the moisture which has frozen in the broad valve.
Coolant leak.
Repair the receiver / a dryer and replace the broad valve.
11
On the party with low pressure sometimes normal pressure passes in negative pressure. The moisture which has frozen in the broad valve. Repair the receiver / a 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.
The receiver / a dryer is faulty.
Repair the receiver / a dryer.
Check up 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.
