I had my radiator flushed and filled on my 1989 Chevy S10 Blazer 3 years ago. Since then I've simply topped it off each year. How important is it to completely flush the system every 2-3 years? Does it really make a difference in the life of the radiator and/or engine?

One question - where's the old coolant going? How much are you adding? If you're adding a lot of coolant on a regular basis, I'd fix the leak first...
