I got the 5 bolts off and the water pump is stuck to the motor, i wasnt sure i should hit it with a hammer or just pull at it. Well the pulling didnt work. Dunno is there something i can use to break the seal?

Make sure you don't miss one hidden under the pulley, tap the w/pump housing at the pulley flange, should loosen up.

Put a couple of bolts loosely back in before you rap on it, so it doesn't fall off and break something. Use a soft hammer or a hammer and a piece of wood.
