Is Cold Pulling Enough To Clean The Extruder

I am hearing mild clicking noises when my H2D printer is printing. It doesn’t happen during the whole printing process but it is something that didn’t happen before.
So to clean the extruder, is nozzle cold pulling enough?
In this link:H2D Regular cleaning and maintenance recommendations | Bambu Lab Wiki
at step 6 it shows how to clean the toolhead and during this process it tells you to remove the front nozzle assembly and the dual extruder. Is there a video showing how to do this?

edit: Ok I did the whole thing lol and it was clean. Also lubricated while at it. I think I confused the sound with what is known as extruder clicking. The only hard part for me was installing back the extruder filament guide for some reason.
