Help Please!!!

I have a 91 240sx with the stock Ka, I had a cooling problem, and I noticed it was the hose that goes from the water pump into the intake manifold, after I changed it, I noticed that after the car heats up, all the pressure is scaping from the reservior tank, the coolant in there is bubbleling and you see the steam leaving the tank, I also see some steam coming from the rad cap, My question is what is causing the pressure to scape to the reservior tank, and how could I fix it?

thanks in advancedAl

when i think of bubling tanks i think blown head gaskets..does your ride smoke at all?...and or are your fans or fan clutch working?..more info needed.
