If you are going to get the original, you will have to order from dealership or hunt some used ones at a slavage yard or ebay. There is one torx screw that attaches the hoses to the inner fender and it is just a matter of getting the clamps off the heater core.

 

i dont have those wierd metal fittings my clamps on the heater core are just those hose clamps that you sqeeze the two tabs together and slide it down

 

That link is to show you an option for repairing them unless you want to drop about $180 for the new ones.

Don't be fooled about those clamps that squeeze together being easy to get off and on, especially if they have never been off. But they are easier to get off than to get back on.
