Maintenance Tips of BYD 1198046000 Expansion valve for Tang EV/Atto3 PRO EV/Yuan PRO EV/Song PLUS EV/Song PRO EV/eT3/D1 EV/YANGWANG U8/YANGWANG U8 PHEV/YANGWANG U8 HYBRID
- First, ensure the system is depressurized before replacing the BYD expansion valve (OE# 1198046000). This prevents refrigerant release and potential injury.
- Check the expansion valve for any signs of damage or blockage. A clogged valve can lead to poor cooling performance in Tang EV, Atto3 PRO EV, etc.
- When installing the new expansion valve, use proper tools to avoid damaging the valve or its connections. This helps maintain a good seal.
- Make sure the valve is correctly oriented according to the flow direction marked on it. Incorrect installation can disrupt the refrigerant flow in Song PLUS EV and other models.
- After installation, evacuate the system to remove any moisture and air. This is crucial for the efficient operation of the BYD expansion valve.
Warning: Refrigerant is hazardous. Always handle it in a well - ventilated area and follow safety procedures when working with the BYD expansion valve (OE# 1198046000).
