I found out the ac pipe line might have a leak because it covered by a hose instead of oem suction hose. I am thinking of replacing it however there are not a single instruction on how do it.
I just want to see if anyone know how to do it with step by step.
This is how the pipe suppose to look it

 

That's a low pressure hose. To remove it, you have to remove the battery, and the air box, and split the plastic grommet that covers the line going into the expansion valve.
