Refer to your vehicle's specific service manual for detailed installation procedures and torque specifications.
Prinsip Operasi
The Denso 471-0710 A/C Compressor operates as the heart of your vehicle's air conditioning system. When the A/C is turned on, the compressor engages, drawing low-pressure, gaseous refrigerant from the evaporator. It then compresses this gas, significantly increasing its pressure and temperature. This high-pressure, high-temperature gas is then sent to the condenser, where it releases heat and condenses into a high-pressure liquid. The liquid then passes through an expansion valve, where its pressure drops, causing it to cool rapidly before entering the evaporator to absorb heat from the cabin air, completing the cycle.
Penyelenggaraan
Proper maintenance of your vehicle's A/C system can extend the life of your Denso compressor and ensure optimal cooling performance.
- Pemeriksaan Sistem Biasa: Have your A/C system inspected annually by a qualified technician for proper refrigerant levels, leaks, and overall performance.
- Pemeriksaan Tali Pinggang: Check the serpentine belt that drives the compressor for signs of wear, cracks, or fraying. Replace if necessary.
- Pembersihan Kondensor: Keep the condenser fins clean and free of debris (leaves, dirt, bugs) to ensure efficient heat exchange.
- Penapis Udara Kabin: Replace your cabin air filter regularly to maintain good airflow and prevent strain on the system.
- Run A/C Periodically: Even in cold weather, run your A/C system for a few minutes once a month to keep seals lubricated and prevent refrigerant leaks.
