I winterized my boat engines last saturday and attempted to add anti-freeze to the cooling lines for my Air Conditioning also.
I must be doing something wrong. I disconnected the intake cooling line in the engine compartment from the Thru-Hull where the water comes from. I put the end of the hose into a 2 gallon can of Anti-Freeze and turned the A/C unit on. The pump started running but the level of Anti-Freeze never changed so it's obviously not sucking it up. I thought maybe there was a problem with the pump ( although it worked fine all summer ) and took the line off at the discharge side where it goes directly to the A/C unit itself. I turned it on again and it pulsed the Anti-Freeze thru the pump and out the discharge side. I then tried blowing into the hose to the A/C unit and couldn't. Any ideas what I might be doing wrong. I know you're gonna ask me what Make ( Brand ) unit this is and I shamefully admit that I don't know. I only know that it provides a Fan-A/C- and Heat.
