Is it leaking? If so then I suggest replacing it with a new one. Loosen up the hose clamps on each end and try twisting the hose off.
if the old 1 is still ok and not collapsing, it will be ok, just tighten the hose clamps, but if you change it, drain the radiator and take the clamps off and pull the old 1 off, then before you you install the new 1, put some grease around the inside of the new hose, that will make it go on easier, then install it and use a couple of screw clamps.
please provide me with more info it will help me assist you ..
If you are going to change the hose, then I would think there is some thing wrong with it, so get a new hose and cut the old hose off.easy way. If you are changing the thermostat and will reuse the hoses, then, drain the radiator, loosing the hose clamp, use a small blade screw driver, and push under the hose and neck of the radiator, and try working in around the neck, and then twisting the hoses, pull it slowly off.Do this to the other end, and the other hoses. on the They make a like a ice pick with a curved hook at the end, for removing hoses, works great, I would not be with out one,
