Maintenance Tips of BYD 1253555400 Coolant temperature sensor for DENZA D9 DM-i/DENZA D9 PHEV/DENZA D9 Hybrid
- First, locate the coolant temperature sensor near the engine coolant passage in BYD DENZA D9 DM - i, D9 PHEV, or D9 Hybrid models. It's marked with OE number 1253555400.
- Before removing the old sensor, ensure the engine is completely cool to prevent burns. This is crucial for safe handling of the coolant temperature sensor.
- When installing the new coolant temperature sensor, apply a small amount of anti - seize compound to the threads. This helps in future removal and prevents corrosion.
- Use a torque wrench to tighten the sensor to the specified torque. Incorrect torque can lead to leaks or inaccurate readings.
- After installation, refill the coolant system with the appropriate BYD - recommended coolant and check for any leaks around the sensor area.
Electrical Shock Warning – The coolant temperature sensor is connected to the electrical system. Disconnect the battery before installation to avoid electrical hazards.
