Fought for hours as gently as I could to get these 36yr old hose clamps off but eventually did the thing I really really didn’t want to do. Totally mashed the last one. No way this seals, right? So what do I do next? I guess for now, I’ll just bypass the front heater too. But I don’t like that long term. Anyone replace this hardline? Where’s the other end and how do I get to it and how painful is it? Appreciate any tips from anyone who has been down this road.
