Hi Track Shy, I am not sure of what brands of anti-freeze you have over there, but I beleive the most important thing about an anti-freeze is it's rust inhibitor quality. Not using a good inhibitor in your radaitor results in the water attacking the aluminium engine parts from the inside so that you don't know you have a problem until it is too late. I had a modified straight six (GM) with only an aluminum water pump and ran without anti-freeze until the water wanted out all over the road. Expensive lesson.....
