Common Failures of BYD 1323717900 Expansion valve for Han EV/Tang EV/Atto3 PLUS EV/Yuan PLUS EV/Dolphin EV/Song PLUS EV/Seal EV/DENZA D9 EV
- Valve Blockage: In Han EV, Tang EV and other models with OE number 1323717900, the expansion valve may get blocked, leading to poor refrigerant flow.
- Inaccurate Temperature Control: Owners of Atto3 PLUS EV and Yuan PLUS EV often face issues where the expansion valve fails to adjust temperature accurately, causing discomfort.
- Leakage: A common problem in Dolphin EV and Song PLUS EV is expansion valve leakage, which affects the cooling system performance.
Maintenance Tips of BYD 1323717900 Expansion valve for Han EV/Tang EV/Atto3 PLUS EV/Yuan PLUS EV/Dolphin EV/Song PLUS EV/Seal EV/DENZA D9 EV
- First, ensure the system is depressurized before starting work on the BYD expansion valve (OE# 1323717900). This prevents refrigerant leaks and potential hazards.
- Next, check the valve for any visible damage. For BYD models like Han EV and Tang EV, a damaged valve can lead to poor cooling performance.
- When installing, make sure the valve is properly aligned. Incorrect alignment in BYD Atto3 PLUS EV and other models may cause refrigerant flow issues.
- Use appropriate tools to tighten the valve connections. In BYD Dolphin EV and Song PLUS EV, loose connections can result in refrigerant loss.
- Finally, after installation, vacuum the system and recharge with the correct amount of refrigerant according to the BYD Seal EV and DENZA D9 EV specifications.
Warning: Do not over-tighten the expansion valve connections (OE# 1323717900) as it may damage the valve or cause leaks in BYD Yuan PLUS EV and other models.
