Its getting time to replace the heater hoses on my wife's Epy. Looking at them, they are all molded and have "permanent" clamps. And advice on doing this job? Can I get the right replacements at Autozone or do I have to go to the dealer. I'm assuming I can grind/cut off the "permanent" clamps and use regular screw on clamps. Accessing the connections under the windshield and over th top of the engine looks tough. Thanks for the advice!
