Common Failures of BYD 1213826500 Expansion valve for Tang EV/Qin PLUS DM-i/eT3/KING DM-i/Chazor DM-i/Seal5 DM-i/Destroyer 05 DM-i
- Malfunction of Expansion Valve 1213826500: Some owners of Tang EV and Qin PLUS DM-i reported abnormal refrigerant flow control, leading to unstable cooling performance.
- Blockage of Expansion Valve: Found in eT3 and KING DM-i vehicles, causing reduced cooling efficiency and potential compressor damage.
Maintenance Tips of BYD 1213826500 Expansion valve for Tang EV/Qin PLUS DM-i/eT3/KING DM-i/Chazor DM-i/Seal5 DM-i/Destroyer 05 DM-i
- Firstly, when replacing the BYD expansion valve (OE# 1213826500) for models like Tang EV and Qin PLUS DM - i, make sure the system is depressurized. This prevents refrigerant leaks and potential injuries.
- Secondly, clean the connecting ports thoroughly. Any debris can cause blockages and affect the valve's performance, especially in high - efficiency models such as eT3 and Seal5 DM - i.
- Next, use the correct torque when tightening the fittings. Over - tightening can damage the valve, while under - tightening may lead to refrigerant leakage.
- Then, check the expansion valve's superheat setting. Proper adjustment is crucial for optimal cooling performance in BYD's hybrid and electric models like KING DM - i and Destroyer 05 DM - i.
- Finally, after installation, run a system test to ensure the valve is functioning correctly and the cooling system operates efficiently.
Warning: Refrigerant is harmful. When installing the BYD expansion valve (OE# 1213826500), wear proper protective gear and follow safety procedures to avoid exposure.
