Vauxhall Corsa coolant draining?
If possible I would like the specific location from somebody with experience.I don't want to unscrew something and get oil pouring out instead of water!
I need to remove the old coolant for a fresh topup with antifreeze.
It is a 1.2l ecotec 16v engine.
Answers:
Find the hose coming out of the bottom of the radiator.
Loosen the hose clamp.
Remove hose.
Coolant comes out,
Refit hose.
Fill up radiator with new coolant.

ont he bottom of the rdiator there should be a petcock(yeah its a stupid name). It'll look like a valve with a wingut on the end . turn it and it should start to come out. make sure you sue the same coolant that came out of it to go back in. ie Dexcool
Why do you need to flush out your coolant system ?FOR £1 You can check if you have enough antifreeze in your car, from your local car spare`s shop , this is a strip of card you dip into your header tank and it changes colour ( you get a little chart with this ) compare the colour to the chart , and if you do need a top up simply take off the cap on the header tank ( where you fill it up with water) take out the water using old rags or an old sponge , top up the header tank with just antifreeze replace the cap then run the engine until the thermostat opens , the water will start to circulate then, the antifreeze will mix with the water already in your engine . This way you do not have the worry of getting Air Blocks in your engine that may cause it to over heat ! The only time you should change the water in any car is if it has had a head gasket problem and the water is contaminated !
undo any water hose lower the better
there are two ways undo bottem hose or get engine running
undo hose to header tank leave engine running ant fill header tank as the levl fall this way you dong get any air in the system.
