I've hunted high and low but can't find a guide on how to change the aux rads. I know the aux rad delete DIY is there but I just want to replace both of mine like for like. Looking for info on how to re-fill coolant and bleed system if needed. Checked on elsawin and it reckons you need a vacuum system to create negative pressure in the coolant system before filling. Any help would be greatly appreciated.
