Hi after previous saga with core plugs etc. (my previous thread) what antifreeze should I now use. With various leaks I've dealt with I think I put in a cocktail of what was to hand & mostly Coma blue. No idea what was already in there as looked like rusty water but did contain antifreeze of some sort but what colour? Pink or blue? Thinking maybe a good idea to flush out & start again.
