Hello,

I am having to replace my bank 1 catalytic converter in my 2015 Honda Accord LX. The part looks accessible but am wondering if anyone has any experience removing the part and if possible any advice in the steps i should follow.

Many thanks

 

A four cylinder only has one bank. The lower rear converter usually wouldn't cause any issue unless it was clogged.

To remove the warm up upper converter, start from the bottom of the car. Remove the 3 nuts at the bottom of converter that's connected to the exhaust pipe. Also remove the converter bracket with the two bolts.

From the top of the engine bay, remove the air/fuel ratio sensor.

Remove the 3 bolts holding the cover on top of the converter.

Remove the nuts and bolts holding the converter.

Then remove the whole converter. Gaskets should be replaced on new converter or if reinstalling old converter.

 

Thank you for the thorough explanation, I will follow your steps once I receive the parts.

 

Would you happen to know the torque spec for the nuts once I re-tighten them?

 

Honda recommends replacing those self-locking nuts. Torque spec. is 54 N.m (5.4 kgf.m, 40 lbf.ft).
