Reinforced high-temperature waterproof durable structure

1. Glass fiber reinforced PA66 pump body, high heat resistance, compatible with all ethylene glycol antifreeze, anti-corrosion against coolant chemical erosion
2. Wear-resistant closed PPS impeller, stable coolant circulation, not easy to jam by tiny pipeline impurities
3. Double-layer FKM fluorine rubber mechanical sealing ring, permanent anti-coolant seepage and dripping
4. IP67 fully sealed brushless DC motor module, isolate engine compartment dust and water vapor to avoid short circuit and motor burnout
5. Original standard waterproof plug connector, stable electrical signal transmission without triggering ECU malfunction codes

Dual core circulation function: Turbo residual heat dissipation + cabin heating boost

1. Post-shutdown forced coolant circulation for turbocharger: eliminate heat soak, prevent turbine bearing aging and oil coking;
2. Cold start small circulation loop: speed up engine warm-up to deliver continuous hot air in winter;
3. Extra cooling for 48V mild hybrid battery pack, avoid power attenuation caused by battery overheating under heavy load driving.

Fully resolve typical auxiliary water pump failure faults

• Slow or insufficient hot air output inside cabin in cold weather
• Turbo overheating risk and power drop after long idle driving
• Hybrid battery overheating warning and limited power output
• Coolant leakage and water stains at pump mounting position
• Continuous abnormal buzzing noise after vehicle ignition
• ECU stores auxiliary cooling pump related fault codes

Rigorous multi-stage factory testing & sufficient spot stock
