I have a 2004 kfx 700 that I changed the coolant, when pouring collant in the radiator it comes out at the bottom of the motor where the water pump is so I poured some in the reseviour but it won't go down. I know the thermostat has to open up, but it got pretty hot and still doesnt go down. Also while running what little coolant is still in the motor is coming out of the drain tube at the bottom of the water pump.

 

water pump seal bad time for new one

 

did you remember to put drain screw back in? i know its simple but it happens
