Features:
The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system, which can transform the harmful gases such as CO, HC and NOx discharged from the automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction.
Installation:
1. Lift the vehicle so that the chassis is clearly visible.
2. Remove the old three-way catalytic converter and its pipe section.
3. Install new the three-way catalytic converter and smear the bolts with anti-sinter lubricating oil.
4. Start the vehicle and check whether a fault code appears

A: It is very difficult to directly change the carrier, and it is recommended to replace the whole section
Q: How to know whether the three-way catalytic converter can work properly?
A: Check whether there is a fault code after starting the vehicle for a period of time, and pay attention to observe whether there is a fault code during subsequent driving
