Hello, after doing some basic maintenance on the unit i found that the lower radiator coolant hose has a slight drip from chaffing, so i looked up the part # in the parts book and found out that both upper & lower coolant hoses are a discontinued item. I have the JD 4045T engine, has anyone run into this yet with their ASV4520 and if so what hoses did you use to make it work. The upper hose is in fair shape but would like to change it also. The big issue is the hoses have to flex, twist and turn since the radiator is on a swing door. Thanks, Mike
