A/C Compressors & Clutches for Suzuki Aerio

A/C Compressor & Clutch for Suzuki Aerio

The A/C compressor and clutch are components of a vehicles A/C unit. The compressors work is to pressurize the A/C thus keeping the refrigerant flowing so that the system can cool. The clutch is what facilitates the pulley to disengage or engage from the power of the vehicle, allowing it to turn when it needs to. The Suzuki Aerio is a compact car with a roomy cabin, and this A/C unit helps cool air to circulate in the car.

Car air conditioners rely on the basic principle of heat transfer, which is that heat will always move from a warm substance to a cooler substance. With the use of a compressor, the AC turns Freon (a refrigerant gas) into a liquid thus concentrating its heat. At this state, Freon is able to be transmitted through conductive pipes thus dissipating the accumulated heat. As it leaves the condenser it returns to its initial gaseous form thus becoming cold. The cooled Freon is then pumped via the AC system through an array of very thin tubes while at the same time warm air is blown over them, cooling it prior to entering the vehicles cabin. The Freon gas in the tubes absorbs the heat from the air, after which it returns to the compression unit and the cycle begins again.

For preparation purposes, new units need to be primed. Priming is simply adding oil to the suction port and the receiver. After determining the proper amount of lubricant and adding it, return it to the car and rotate it 10 to 20 times using a wrench.

If properly engaging, the central part of its clutch will move along with other parts like the peripheral pulley. However, if it does not rotate, a loud noise like a squeal will be heard indicating a locked-up compressor and consequently, the dryer.

• Cabin temperatures are higher than normal since the failing unit is not able to regulate the flow of the coolant.
• A loud squeal sounds as it is running. The squeal is a result of its internal components breaking and its internal bearings failing.
• The compressor clutch is not moving, and thus, it is permanently activated or it may not work at all.

• Ambient heat sensors and coolants: These are thermistors whose values change with heat.
• Throttle position Sensor: It reports motor-engine demand conditions to the automobile management computer.
• Power steering pressure switch: This one reports on high-pressure conditions, that is, a load placed on the motor by the power steering pump.
