91 integra over heating

[94 Ej1]

my car over heats after about 20mins of driving... when i feel the upper radiator hose its hot and the lower radiator hose is cold. i was think maybe its the t-stat but im not positive does anyone else have an ideal?

+1 change your thermostat, and make sure it's bled properly.

you have to fill the radiator with antifreeze, then start the car with your radiator cap off. Put your heat on hot and the fan blowing on high. Watch, for about 15 mins as all the bubbles rise to the top of the rad. Make sure to keep the rad. full with coolant, tho.
