1) Rubber will soften when heated, so yes, BUT...
2) the cooling system on a car is a pressurizedenvironment - so the hoses should actually be firm due to the internal pressure.

Why are your radiator hoses rock hard when your engine is hot?
Your Car Hase A Closed Cooling System. So Your Hoses Will Feel Hard While The System Is Hot. When It Cools They Should Be Somewhat Soft Without Cracks In Them Or Deteration. If They Are You Need To Have All Hoses Checked And Replaced As Required. More Engines Are Destroyed By Overheating Than Oil Loss By Far. Best To You

What cause a car not to produce hot air inside the car?
It could be a number of things, depending on what kind of car you have depends on some components that could be the cause of the problem. First thing I would check is heater hoses/heater core, if both the hoses are hot with the car warmed up and the heater on, then that eliminates blockages in the heater core/ hoses. If they are not both hot, then you may have a blockage in the hoses/core, or a faulty heater valve or controller. Another thing that may be the problem, is the blend door actuator, it controls how much hot/cold is allowed to enter the passenger compartment. That's most of the heating system for most vehicles. If you still cant figure it out, then its probably time to take it in for service.
What will cause the car temperature run hot if you have replaced the radiator and the thermostat?
the hoses leading to and from your radiator might be clogged. If you had a rusty radiator, the rust may have clogged the hoses that carry the coolant. you should check all your hoses and even flush them out.
What causes your car not to heat up?
First you need to make sure it is actually not heating up. Do this by checking to see if the radiator hoses are getting warm after running for 10-15 min. Be careful they could be HOT. If the hoses are hot then the heater core is plugged and will need to be replaced. If hoses do in fact not get hot then the thermostat is most likely stuck open. removing it will tell the tale.
At times your car smells like the engine is hot?
When your car smells like the engine is hot, is the engine hot? If it smells hot and the engine is not hot, then you have coolant escaping onto a hot surface. You may have bad radiator hoses, a leaky radiator, a blown gasket, or some other problem. You need to find the leak.
