Aeroblitz

Hi, I'm new to this forum and to forums in general. I have a 99 civic hatch with a godspeed radiator. I'm not sure that the coolant is going through to cool down the engine. i filled it but it seems to stay at the same level. while driving the engine gets heated very quickly. the temperature on the cluster first stays at cold but after about 2 or so minutes of driving, it raises up halfway and stays there for as long as i drive. i don't know if that is normal... any feedback would be greatly appreciated.
