Top radiator hose

Our 2004 LY has 38K miles. We are the 2nd owners, and love it. This is our 4th RV, second class A Moho.
We are preparing to head out for our winter trip south, Texas & Arizona.
When looking over things I discovered a water leak at one of the heater hoses that supply hot water to the rear heater in the floor by the doorway. This led me to take a closer look at all the hoses. I decided to change all the hoses, flush the motor and add fresh coolant and put on a new belt also. I soon discovered all that is certainly easier said than done. In particular the upper radiator hose. I have tried everything I know to access the clamp by the radiator that holds the hose on. It has the original clamp the compression type that you have to squeeze to enlarge to release the hose. I have tried to gain access from the front under the hood and have removed the engine cover and come in from the backside. No luck either way. I get close from the front but the position that the clamp is in on the hose will not allow any tool (needle nose pliers both strait and 90curved on the ends)to get a grip on the clamp, there is just no room to get this da***** clamp off. If anyone out there has faced this situation and has a solution to it I would be grateful. Thanks

I don't have any solution for you. Can you cut it off and just replace it with one you can get at???
The top hose will be the one in the worst condition as it gets all that engine heat, so it should be changed.

Take a look at the special tools on this link:

One of these should be what you are looking for. Most are available at AutoZone and similar auto parts stores; and while they may be an extra expense, you'll have the right tool for next time you need to change radiator hoses.

Thanks for the replies

Thanks for all the replies. My best bet would be the cable type pliers. I am not over stating when I say there is no way I can see to access this clamp. I conceder myself to be a decent shade tree mechanic and have always maintained my own vehicles. But this AirStream may be going to a shop. . I changed one of the heater hoses, took a close look at the rest and made the decision that even though its just hoses I think I may be better off turning it over to a pro. I may need a belt and idler pulley also.
I have contacted the AirStream dealer in my area and they do not work on the chassis. There is a shop that has been recommended by an RV dealer (Price Professional Auto) and also advertises the fact they work on Workhorse chassis that I may take it to them.
