I can obviously see I'm late to the discussion. The dry condition of the hoses should have been a good indicator of a leak from the beginning. My rule of thumb has always been to pour in coolant or just water in summer months, to find the leak responsible for the dry hoses first. Then start figuring out what needs to be replaced. However, I will add a tip here that you should not replace the short piece of connecting hose on the t-stat housing with ordinary hose. Try to save the original one if possible. It is made to weather the high temperature near the exhaust manifold there. Also, don't use screw clamps if at all possible. They will cut into the short hose and start a new leak.
