BYD ATTO3 AC Compressor

Description

Powerful Cooling, Instant Relief: 
Adopts new generation piston and swash plate technology, optimizes internal fluid dynamics design, and significantly improves refrigerant compression efficiency. Compared with similar products on the market, the cooling speed is increased by 30%, allowing you to enjoy a cool ride in the car on a hot summer day.
Ultra-Quiet Operation: 
Built-in high-precision bearings and rigorous dynamic balance test, effectively reduce the vibration and noise during high-speed operation. Say goodbye to annoying noise, whether it is a family trip or business commute, can provide you with a quiet and comfortable driving environment.
Energy-Efficient Performance: 
Optimized electromagnetic clutch design, precise suction, reduce unnecessary engine load. While providing powerful air-conditioning, it effectively controls fuel consumption and saves you money.
Durable & OEM Quality: 
adopts high-strength aluminum alloy shell, which is resistant to pressure and corrosion. The internal core components have been subjected to stringent durability tests (simulating more than 1500 hours of continuous operation) to ensure stable performance and a service life far exceeding the industry standard. We promise to provide superior quality comparable to the original.
Perfect Fit, Easy Installation: 
is built strictly according to OEM standard data, the interface, size and fixing position are 100% matched with the original car. No need to modify, plug and play, significantly reducing the installation difficulty and time cost. (We strongly recommend installation by a professional technician)

Installation steps

Step 1: Preparation & Safety Checks
1. Disconnect the power supply: Disconnect the negative terminal of the vehicle battery to prevent short circuit.
2. Recover refrigerant: [Core Steps] Use a professional refrigerant recovery machine to completely recover the remaining refrigerant in the air conditioning system. It is strictly prohibited to discharge the refrigerant directly into the atmosphere.
Step 2: Removal of Old Compressor
1. Remove the belt: Loosen the belt tensioning wheel and remove the serpentine belt (serpentine belt).
2. Disconnect lines: Disconnect the high and low pressure lines and electrical connectors connected to the compressor.
3. Remove bolts: Unscrew the fixing bolts and remove the old air conditioning compressor.
Step 3: New Installation & System Flush
1. Check the new product: Compare the old and new compressors to make sure the model, interface and pulley are identical.
2. Add Oil: [Core Steps] Confirm whether the new compressor contains or needs to add the specified type and dosage of PAG refrigeration oil. Please refer to the vehicle service manual.
3. Replacement of accessories: In order to ensure the validity of the warranty and the health of the system, it is necessary to replace the drying bottle/tank and the expansion valve/throttle with new ones.
4. System flushing: If the old compressor was damaged due to an internal failure (e.g., “pulling” or “holding”), the air conditioning lines, condenser and evaporator must be thoroughly cleaned with a special flushing agent to remove metal shavings and contaminants.
Installation of new product: Install the new compressor in place, tighten the fixing bolts according to the specified torque, and connect the high and low pressure pipelines (be sure to replace the sealing O-ring with a new one) and electrical connectors.
5. Install the belt: Install and tighten the belt.
Step 4: Evacuation & Recharging of the system
1. Connect the equipment: Connect the manifold pressure gauge and vacuum pump.
2. System Evacuation: [Core Steps] Evacuate the whole air conditioning system for at least 30-45 minutes to completely remove air and moisture from the system. Hold pressure for 15 minutes after evacuation to check for leaks.
3. Refill Refrigerant: Use a refrigerant charger to accurately fill the refrigerant according to the type and gram weight indicated on your vehicle's nameplate or service manual.
Step 5: Startup and Testing (Final Checks)
1. Power Connection: Reconnect the negative battery terminal.
2. Start Test: Start the engine, turn on the A/C switch, set the airflow to maximum and the temperature to minimum.
