PTFE-coated bearings and corrosion-resistant materials ensure reliability in humid or saline environments.
Diagnostic Readiness:
Detects faults like P261B (coolant pump performance) via OBD-II scanners, simplifying troubleshooting.
Installation & Maintenance
Tools Required: Torque wrench (8–12 Nm), coolant vacuum filler, OBD-II scanner.
Steps:
Coolant System Preparation:
Drain and flush old coolant using a 50/50 ethylene glycol mixture to prevent chemical degradation.
Pump Replacement:
Disconnect the battery, remove the old pump, and install the HDH-1309030 with 8–12 Nm torque.
Post-Installation Checks:
Prime the system, test for leaks, and reset fault codes using BYD diagnostic software.
Maintenance Tips:
Replacement Interval: Every 150,000 km or 5 years, whichever comes first.
Failure Symptoms:
Overheating: Caused by low coolant flow or air pockets in the system.
Whining Noise: Indicates bearing wear or impeller damage.
