This is a step by step demonstration of a coolant change and flush using a Toyota Scion TC 2005. I hope you will find my version helpful.\r

Although I am changing the antifreeze on a Toyota Scion TC 2005 the process I demonstrate should suffice on most radiator equipped vehicles . A radiators primary function will be the same in all cars and thus all radiators work pretty much the same way. The difference may be the ex layout of components. For example the radiator cap and drain plug may be in different locations on other vehicles.\r

There are many different procedures to flush a vehicles cooling system. I only demonstrate the version I used on this Toyota Scion. Some watchers may have opinions on methods they feel are more appropriate for flushing and replacing automobile coolant.
