제네시스BH P0420 - 1차 촉매 교체 방법 (how to replace of 1st catalyst converter for genesis)

This DIY video shows how to replace the primary catalyst for P0420 (reduced purification capacity). It also includes a video showing how to replace the catalytic converter connecting the primary and secondary catalysts. The vehicle in question is a 2010 Genesis GDI V6 engine with approximately 140,000 km on it. I drove for several days with the coolant level set to HIGH, adding coolant, which likely caused the catalyst to fail prematurely. For reference, the manufacturer's warranty covers the catalyst for 7 years or 140,000 km. (This means it's a rare component. ^^)
