Coolant Service

[PolarWhite]

According to outside source, AAA and Car Care Aware Council, the #1 cause of mechanical breakdowns is cooling system failure. I only drive about 8500 miles per year. With that in mind, how long would it take to put 100k on my Yaris. Why anyone would wait for 10 years to change the antifreeze is beyond me. Maintenance is everything on any kind of equipment if you want it to last. I have seen many cars with rusted out heater cores, engine blocks and eaten up radiators because they weren't ever maintained. Why would Toyota care if you waited til your Yaris was 10 years old to change the antifreeze, does anyone here have a 10 year warranty. Hopefully your radiator will rust and fall out and you will go back to them for your new radiator. All antifreeze has additives such as rust inhibitors and corrosion inhibitors, those wear out just like the additive package in oil does. When those inhibitors are gone, you have basically water left. What happens if you put water in a metal bucket and leave it for 10 years? Just a thought to ponder.
