yet another question, so my a/c coolant/free-on hose has a leak in it so when I charge my a/c she will run good for about 1-2 days and then will go back to blowing room temp air. I have tried the indicator and sealant which worked well for a couple of days but eventually failed me. I took it to the local ac shop and they wanted several hundreds of dollars for what seems to be a simple fix only reason why that price tag is giving me heart burn is my rig has 436k on it and have other things to worry about. Here in tucson where it is 110 degrees in the summer ..... yeah ac is sometimes a nice thing to have lol. Does anyone have any fixes to try even temporary? I was thinking of trying a piece of bike inner tube and a hose clamp over the few punctures to stop the coolant from leaking... Any ideas????
