Re: please help major overheat problems
I suspect you have the plastic impeller type water pump and this has just exploded, easy to check, remove the top hose from the radiator and start the car, if the water flows then it'll be OK, but if the water doesn't then it's cambelt change time too. If that's fine then go for for a compression test. The other option is a stuck closed thermostat, very rare but it has happened.
I suspect my first guess will be the problem though as your not geting flo through to the heater matrix and that depends on the water pump to push it round.
