my car is building up a lot of pressure in the radiator and the hoses. if i take the cap off in he morning and watch the coolant there is no bubbles but after i drive it for a bit and then try to take he cap off it shoots coolant everywhere any one know what is wrong

It's supposed to do that.

Hence the warning on the cap: Do not remove when hot or hot coolant comes out and scalds you.

After you drive it does it try to spit coolant out the reserve tank too?

the only thing i havent checked is the water pump itself cause the car is now parked and getting a single TO4 turbo added to it so i havent got a chance to see if the water pump does the trick or not.

have you flushed out your cooling ssystem latley?

mine had tons of deposits in the cooling system which i thought was my problem but it wasnt but i would have the cooling system flushed real good and run a good cleaner through the system as a first before i went tearing the water pump off.

What year is your car? N/A TURBO?

sounds like a classic case of a broken water jacket in one of your irons, after starting the car cold grab the upper radiator hose with the cooling system sealed and see how long it takes to feel like it is pressurizing like a balloon, if it takes less than a minute then i would have to say it is time to tear down the engine. there is no other reason that much pressure could be getting into the cooling system aside from gasses from the combustion chamber.
