jwkwak3 Posted July 22, 2019 Report Share Posted July 22, 2019 Well the gremlins are active in my 2011 Mainstreet. I need to change out out one of the A/C hose's. The question I have is do I need to add some oil back to the system after the change? I know I will need to pull a vacuum before re-charging the system just not sure about oil addition.
