The Honda City GM6 (also referred to as the T9A in some regions) is the 6th-generation model of the Honda City, produced roughly between 2014 and 2020. The air conditioning (A/C) pump, also known as the A/C compressor, is a critical component of the vehicle’s air conditioning system.

🔧 Honda City GM6 / T9A A/C Pump Description:

1. 

Function:

• The A/C compressor is responsible for compressing and circulating the refrigerant through the A/C system.
• It increases the pressure and temperature of the refrigerant before it moves to the condenser.
• Driven by the engine via a serpentine belt or V-belt, it engages using an electromagnetic clutch.

2. 

Specifications:

• Type: Scroll or rotary compressor (varies by OEM supplier and market)
• Voltage: 12V electromagnetic clutch
• Refrigerant: R-134a or R-1234yf (depends on region and year)
• Drive Type: Belt-driven
• Oil Type: PAG oil (specific grade varies; usually PAG 46 or 100)

3. 

Common OEM Suppliers:

• Sanden
• Denso
• Keihin (subsidiary of Hitachi, sometimes used by Honda)

4. 

Common Issues:

• Clutch failure (won’t engage)
• Refrigerant leaks (from seals or connections)
• Bearing noise (whining or grinding)
• Low cooling efficiency (could be due to compressor wear or low refrigerant)

5. 

Replacement Notes:

• Always replace the receiver drier or accumulator when replacing the A/C compressor.
• Flush the system and ensure no metal debris is left behind.
• Recharge with the correct amount of refrigerant and oil.
