Last night as I parked up on my drive I noticed a bubbling noise, and the temp gauge was approaching 100 deg. Much warmer than usual! I popped the bonnet and the cap was relieving pressure and spewing some water out of the pipe.

Would someone please tell me where the engine block drain plug for the coolant is?
I need to replace the thermostat and would like to completely flush the system which, ideally, would mean the whole block.
Failing that, would a serious and long flush through the rad hoses be adequate?
