4.12.1. Check of filling of a coolant


Main units of system of cooling of air

1, 8. A sucking-in hose
2. A tube with a liquid coolant
3. Evaporator
4. Broad valve
5. Final hose (engine of 2,7 l)
6. Final hose (engine of 3,4 l)
7, 12, 13. A tube with the liquefied coolant
9. Compressor
10. Condenser
11. Moisture separator

1. Warm up the engine.
2. Transfer a rychazhok of a regulator of temperature to the situation corresponding to the lowest temperature, establish the highest speed of the fan. Open doors.
3. Check turning on of the compressor at which click of the electromagnetic coupling is distributed, and the central part of the coupling starts to rotate. After the system leaves on an operating mode, compare temperature of two tubes of the compressor (shooters specified fastenings of tubes). If the temperature to the touch poorly differs, filling is necessary.
4. On the working conditioner bring the thermometer to the central part of the channel of an air outlet. Air temperature on an exit from the channel should be on 17-20 ° From below ambient temperature. If the air temperature very high, for example 45 ° With, air temperature on an exit from the conditioner can reach 15 ° With, though in as a rule temperature of the cooled air on 17-20 ° From below ambient temperature. If the temperature of the cooled air is higher than standard, conditioner refueling by a coolant is necessary.
5. Further works with the conditioner are beyond this management and should be carried out by the prepared personnel.
6. Check a coolant condition through viewing glass (it is specified by an arrow). If at the working conditioner in glass foaming is observed, the quantity of a coolant is not enough. At high temperature of environment in viewing glass bubbles, even can be observed at normal filling of a coolant. When the conditioner is switched off and the quantity of a coolant in norm in viewing glass is observed small foaming which disappears subsequently.
