Going round in circles with this so hope someone can help. I have a 100e Continental which needs coolant changing. Whats the right stuff to use, I thought it was NAP free but not so sure now after reading all the maufactures info.

HI, if nothing else you have made me discover at least 6 different types of Coolant/antifreeze. Having had a quick look I have gone for the 'Green' as I seem to recall my earliest cars had green antifreeze and they dated nearest in years to the age of the boat engine. The only other info I know is never mix the different types. Hope that helps a bit. Kgarla
