Can this be blamed on the Thermostat?

    The question is the outlet radiator hose from the engine to the radiator never gets HOTTT.

    The upper inlet radiator hose is HOTTTT. And it, the upper hose, expands a bit when the vehicle has been driven.

    What could be the cause of this?

    Radiator? Cap? Thermostate? Leak?

    Any help would be appreciated.

    Does your car ever overheat? If it doesn't I'll assume nothing is really wrong. If it does, your cooling system might need to be bled off. Air could be trapped in the upper part of the cooling system.

    thats supposed to happen, its completly normal. when hot water/coolant enters thru the top hose, the heat causes the hose to expand. things expand when they get hot. when the cool water/coolant leaves the radiator out the outlet hose, well, its not supposed to be hot because the coolant inside has been cooled off in the radiator. hot water rises/cool sinks, which is why the top one is the hose for the hot water and the bottom hose is for the cooled water. so your car is fine unless you see that your car is leaking something or if you start overheating.
