Yes, a bad hose will make the vehicle run hot. Sometimes when a hose is bad when it gets hot it will collapse cutting off the flow of the coolant. Also, you may have a blown head gasket. To check for this (1) remove the radiator cap. (2) crank engine up and let it sit and idle and warm to operating temperature. (3) watch the coolant as it circulates through the radiator. IF the head gasket is blown there will be bubbles in the coolant. NOT normal bubbles, rather large ones. Since summer is coming on you can remove the thermostat and drive the vehicle but not for long distances and not in heavy traffic either. One other thing - if your car is equipped with an electric cooling fan the fan may not be operating right. One symptom of this is when the vehicle is moving down the road it will run cooler as opposed to sitting at a red light and running hot. Sometimes the fans run so quiet one can't hear it running. If it is running hot while sitting still idling, yet will cool off while driving down the road one can bet they have coolant fan problems. One can check this simply by cranking the vehicle and, with the hood up, watch for the coolant fan to come on once the vehicle reaches operating temperature. If the fan never come on and the vehicle runs hot one can be rest assured the coolant fan is NOT working. That could be caused by several things ranging from a blown fuse, a faulty relay, or a burned out fan motor. If you need more help click my icon and ask for it.

your coolant levels are low or you are leaking coolant out of the system somewhere. Another possibility is if the coolant is topped to proper levels you have installed either a faulty thermostat or the wrong one all together. Check your coolant levels first!!!!!
It sounds like one of the following: Broken head gasket, cracked block, or cracked cylinder head. hopefully just a gasket, that's the easiest to fix. but get the system pressure checked, and have a cylinder compression test done. If you didn't have enough anti-freeze in the system this winter it could have frozen and cracked just about any thing. Best of luck.
Is the coolant level low? Any other leaks in the system? By the 2 hoses, I take it to mean the hoses going to the heater core? Is the heater core leaking? Possibly just air trapped in core when you changed the thermostat? The thermostat wasn't put in upside down was it?
probably your heater core or leaky hoses. look for any leaks and replace that section of hose. or even buy another thermostat that opens at a lower tempereture than the current one.
sqeeze the hoses to see if they are soft..thy can flaten under pressure...but its probly fan not working [ if electric] or bad waterpump..use 50/50 coolant
If your car is fairly old, you may have corrosion in your radiator, which would reduce its effectiveness. You should have a mechanic look at that. You can get a replacement radiator for a couple hundred bucks.
