I have a 1.4 Corsa B automatic (S reg) and recently I've noticed the temperature has been going up more than usual, so I've decided to have a crack at replacing the coolant mixture. Annoyingly, I can't find the bottom radiator hose that the oily hand of Haynes mentions, only two large hoses going into the top of the radiator at either end, and the thermostat switch at the bottom left (from looking into the engine bay) as well as the auto transmission cooling hoses (I assume). Anyone got any ideas as to my next course of action? Should I drain the radiator at the thermostat switch?
