Best way to replace heater hose fitting
 

Any tips on the best / easiest way to remove the heater hose fitting on the passenger side head with the engine still in the car?

Video shows head out of car but you can do same with it in the car..

Thanks for the reply. Looks easy enough in the video. Hopefully it's that easy in my case. :)
