How to Perform Manual Exhaust Self-Cleaning on the Great Wall Pao?
2 Answers
The method for performing stationary exhaust self-cleaning on the Great Wall Pao is as follows: Turn on the ignition switch to power on, then press and hold the DPF regeneration switch behind the steering wheel until the dashboard prompts to start the vehicle and idle. Next, start the vehicle, and the engine speed will automatically maintain at 2000 rpm until the dashboard displays that the self-cleaning is complete. Then, turn off the vehicle. If the operation returns to the initial state halfway, you can disconnect the power and restart the operation. Powertrain Specifications: The diesel model is equipped with the GW4D20M engine, while the gasoline model uses the GW4C20B engine, both offering robust power. The diesel GW4D20M delivers a maximum power of 120kW at 3600rpm and a peak torque of 400N.m between 1500-2500rpm. The gasoline GW4C20 produces a maximum power of 140KW within 4000-5500rpm and a peak torque of 360N.m between 1800-3600rpm.
I've been driving the Great Wall Poer for quite some time, and the manual exhaust self-cleaning procedure requires careful attention. Typically, when the exhaust warning light on the dashboard illuminates, it's time to act: find an open area to park, ensure the vehicle is stationary and in neutral, and engage the handbrake firmly to prevent movement. Turn off all electrical devices like air conditioning and lights to conserve power. Then locate the regeneration button—usually found on the instrument panel near the steering wheel—and hold it down for a few seconds until the indicator light flashes. The entire process takes about 20 minutes, during which the engine RPM may increase, and white smoke emission is normal, so don't panic. Wait until the light goes off, indicating the process is complete. This clears DPF blockages, prevents carbon buildup, and extends the vehicle's lifespan. Remember to perform this only in well-ventilated areas, as exhaust fumes are toxic and harmful. Regular execution avoids major overhauls and ensures smoother engine performance.
