Coolant flush interval
looking to see when you guys generally flush your system.
Its been almost three years since a full coolant flush (new radiator) and mines starting to look murky and it's not bright green anymore. Considering a flush soon

The additives are generally rated at 2 years on the old green stuff.

Re: Coolant flush interval
TIP - flush it completely clean - use 1 cup of Lestoil with water. Drive it for a day or 2.
Then with your coolant of choice, USE DISTILLED WATER. Your cooling system will look new even 15 years later. It makes that big of a difference.
