The longer you leave your coolant in, the more time it has for rust to develop and clog the lines. Change the coolant more often, and use deionized water if possible. The less minerals in your coolant the better. I change mine once each year, it's not a difficult or expensive thing to do.

Ethylene glycol is supposed to be changed every two years. Many on this forum change it every year. It breaks down into a mild acid eventually and the anticorrosion additives get used up over time, so you want to get it out of there in a reasonable time.
Propylene glycol lasts longer, and they recommend five year change intervals for it. Not sure if it's compatible with our engine internals.
I use ethylene glycol and distilled water 50/50. I change it every two years, and have never seen a corrosion issue (the car sits for 6 months every year on jackstands). I use that much glycol because over the winter my unheated garage can get down below -10 C and it gives me better corrosion protection. I don't see summer temps. above 35 C so overheating isn't an issue.

Deionized is what you use in chem lab at school, I think it's filtered a little better than distilled water you can buy at the store. I usually use distilled water, but I think I'm going to filter it more next time, using a Brita water pitcher.

PS, Wal-Mart = evil. Their execs are way too rich, and their employees are way too poor, and their stores are always dirty.

That would probably still have minerals in it though right?
