Bottom hose gets hot when the thermostat opens and antifreez is pushed into the radiator to cool (the fans also come on). If lower hose never opens than you may have defected thermostat. Than it will definitely overheat.

Some days when it is very cold I can drive for 30 minutes(constant cold air hitting the engine) to work and the lower hose never gets warm. However, stop the car for less than 5 minutes and it will get warm (no cool air).

hey thanks for replying, i feel better now cause my car has never overheated for two years now but i was just a bit concern as to why the lower rad hose wasn't hot when i was checking it lately, i suppose it cuase its winter and i'm using the heater as well so it doesn't give the engine a chance to heat up hot enough to open the thermostat while summer it would open up
