I'll be changing the water pump this weekend but after I saw the old green coolant leaking out I now know it had the wrong stuff in. I've bought Comma G40 red but I need to give it a good flush then replace.
I think I'm ok with the flushing bit, I've read various advice on flushing ranging from removing the drain plug, sticking a hose in the filler and running the tap for a bit to filling with water, running the car up to temp with the heater on then draining, repeating at least five times until the water runs clear.
As for refilling, again advice ranges from jacking the back up and you'll be fine to don't even both with DIY as it needs to be done with a vacuum pump??
What do the panel think?
Also, what's the volume of the system and when diluting the Comma do you need deionised water or will tap water do?
Thanks
