Ok, working on a rig this week that has almost all the crimp fittings leaking oil, tranny fluid, even power steering fluid... these are the aluminum crimp jobs that crimp the rubber hoses to the tranny and engine oil cooler hard metal lines. I think the only crimp fitting that is not leaking (or at least I can't tell) is the Refrigerant line. Yeesh, I hear its often triggered by cold weather, but man this is ridiculous- By the way, the rig is a friend's and its not a Ford, but it has the same style of crimp connectors, they just look way cheaper.
From what I have read, these fittings are notoriously leaky, and buying the entire replacement line for each of those is spendy and does not solve the problem. Thinking about just buying fresh hose and some quality hose clamps and cutting away the old crimp fittings and just pushing the hose over the barb and clamping it with the hose clamp(s).
For anyone that I have confused, the fitting looks a lot like this
Any suggestions on how to make these suckers never leak again?
