Coolant complete flush and change
Can someone point me to a step-by-step guide to completely flush out the old coolant from the engine (2.0 TS plastic top) and replace it? I know there must be one on here somewhere but search is bringing up too many matches.
The car is currently SORN'd an not insured so I can't drive it anywhere.
I found one once that alluded to removing the thermostat and running a hose through some of the pipes. Is that a good idea? Will I need a new thermostat gasket?
I need to do it as some time ago I topped the green stuff up with red stuff before I new they shouldn't be mixed (ooops...).
