Car do’s and don’ts

Car do's and don'ts - this section covers the basics of car maintenance like maintaining the refrigerant level and cleaning the evaporator. A quick check, and quite a few of the problems that plagued you will be no more...

• Clean condenser during normal service of the car Dirty and clogged condenser results in A/C tripping and less cooling.
• Maintain proper refrigerant level. Less refrigerant results in less cooling. Excessive refrigerant results in less cooling.
• Add at least 20 CC of DENSO-6 oil to the compressor during refrigerant charging. Adequate quality of compressor oil prevents poor pumping and premature wearing of internal components.
• Clean evaporator properly to remove dust and foreign particles. Clogged evaporator results in less air flow and reduced cooling.
• Adjust fresh air and heater cable properly to close damper’s firmly. Unadjusted cable will result in mixing of hot air with cool air.
• Refer to the owner’s manual on proper usage of A/C controls. Proper usage of A/C control will give optimum cooling.
• Adjust proper engine RPM. Less rpm will result in stalling of engine and less cooling.
• Check coolant level and ensure proper engine tuning. This will prevent overheating of the engine.
• Check position of accelerator cut off switch in 1000cc cars. Improper position of accelerator cut off switch will result in tripping.
• Check proper belt tension. Loose belt will slip and overtight belt will result in noise and premature failure of magnetic clutch of the compressor.

• Do not use A/C with fresh mode open. This will lead to mixing of outside air with cool air inside thereby reducing cooling effect.
• Do not operate with A/C on. This will result in mixing of hot air with cool air.
• Do not operate A/C without refrigerant in the system. This will result in premature failure of compressor.
• Do not leak check the A/C system with more than 20KG/CM2 pressure. Higher pressure may result in damage to A/C components.
• Do not leave A/C joints open. Moisture tends to enter the A/C system if the joints remain for a long time.
• Do not charge refrigerant in the A/C system without carrying out proper vacuum. Improper or no vacuuming of the A/C system results in less cooling conditions.
