Especificacions del producte

Guia d'instal·lació

Installing an AC compressor requires specialized tools, knowledge of automotive AC systems, and proper handling of refrigerants. It is molt recomanable to have this procedure performed by a certified automotive technician to ensure correct installation, system integrity, and personal safety. Refer to your vehicle's specific service manual for precise, step-by-step instructions and torque specifications.

General Installation Steps (Consult your vehicle's service manual for specific instructions):

1. Descàrrega del sistema: Safely discharge the refrigerant from the AC system using appropriate recovery equipment. This step is critical and must be performed by a qualified technician.
2. Eliminació de components: Disconnect electrical connectors, refrigerant lines, and mounting bolts from the old compressor. Carefully remove the old compressor from its mounting location.
3. Buidat del sistema: Flush the entire AC system (condenser, evaporator, and lines) to remove old oil, debris, and contaminants. This is crucial for preventing premature failure of the new compressor.
4. Instal·lació de nous components: Install the new Denso compressor, ensuring all mounting points align correctly. Connect refrigerant lines with new O-rings (lubricated with appropriate PAG oil) and secure all electrical connectors.
5. Vacuum and Recharge: Evacuate the system to remove air and moisture, then recharge with the correct type and amount of refrigerant and PAG oil as specified by your vehicle manufacturer.
6. Prova de fuites: Perform a leak test to ensure all connections are sealed and the system is airtight.
7. Comprovació de rendiment: Start the engine and test the AC system for proper operation, cooling performance, and absence of unusual noises.

Principis de funcionament

The Denso NEW COMPRESSOR W/CLUTCH - 471-7026 is a critical component of your vehicle's air conditioning system. It functions by compressing low-pressure refrigerant gas from the evaporator, increasing its temperature and pressure. This high-pressure, high-temperature gas then flows to the condenser, where it releases heat to the outside air and condenses into a high-pressure liquid. The liquid refrigerant then passes through an expansion valve, which reduces its pressure and temperature, causing it to vaporize in the evaporator. As it vaporizes, it absorbs heat from the vehicle's cabin, thus cooling the air before it is circulated into the passenger compartment. The integrated clutch engages and disengages the compressor from the engine's drive belt, allowing the AC system to be turned on or off as needed by the driver.

Manteniment i cura

Proper maintenance ensures the longevity and efficient operation of your AC compressor and the entire air conditioning system.

• Comprovacions periòdiques del sistema: Have your vehicle's AC system inspected annually by a qualified technician. This can help identify potential issues before they become major problems.
• Nivells de refrigerant: Ensure proper refrigerant levels. Low refrigerant can cause the compressor to overwork, leading to premature wear and failure. Only a qualified technician should check and adjust refrigerant levels.
• Inspecció de la corretja de transmissió: Periodically check the serpentine belt that drives the compressor for signs of wear, cracks, fraying, or improper tension. A worn or loose belt can lead to reduced compressor performance or complete failure.
• Neteja del condensador: Keep the condenser (typically located in front of the radiator) free of debris, leaves, insects, and dirt. A blocked condenser reduces heat exchange efficiency, forcing the compressor to work harder.
• Run AC Periodically: Even in cold weather, run your AC system for a few minutes once a month. This helps to circulate refrigerant and oil, keeping seals lubricated and preventing component degradation.

Resolució de problemes comuns

If your vehicle's air conditioning system is not performing optimally, consider the following common issues. For any persistent or complex problems, consult a professional automotive technician.

• No Cold Air:
  • Low Refrigerant: The most common cause. This usually indicates a leak in the system.
  • Compressor Clutch Not Engaging: Check if the clutch on the compressor is spinning when the AC is turned on. A faulty clutch or electrical issue can prevent engagement.
  • Fusible cremat: Inspect the fuses related to the AC system in your vehicle's fuse box.
  • Faulty Pressure Switch: A malfunctioning pressure switch can prevent the compressor from operating.
• Unusual Noises from AC System:
  • Squealing or Grinding: May indicate a failing compressor bearing, clutch, or a worn drive belt.
  • Rattling or Clicking: Could be loose components, a failing clutch, or internal compressor issues.
• Refredament intermitent:
  • Often caused by low refrigerant levels, an intermittently faulty pressure switch, or an electrical connection issue.
  • Can also be a sign of the compressor cycling on and off due to high system pressure.

Important: Attempting repairs without proper knowledge and tools can cause further damage or injury. Always consult a professional for complex diagnostics and repairs.
