    Your coolant is the Toyota Long Life Coolant antifreeze which is basically your normal ethyl glycol coolant minus the phosphate, silicate, and borate that is used in most anitfreeze as corrosion inhibitors. Supossedly, they substitute other additives. Prestone makes the identical long life ethyl glycol coolant minus the phosphate, silicate, and borate and it's called Prestone® Extended Life 5/150 Antifreeze/Coolant. I would use this Prestone as it is chemically identical to the Toyota Long Life and costs about half the price. I suspect Prestone actually makes the Toyoya stuff because I know it's made in the USA. More important than all of this is that you use distilled water as that really does protect your aluminum radiator from corrosion over time. I always add a bottle of Redline Water Wetter to my cars after I flush them as it helps cool the engine about another 10 degrees, but thats your option. The proper steps are 1. drain the old stuff 2. fill with distilled water and bring to operating temperature with the heater on high 3. drain the water 4. fill with 50/50 mix of new coolant and distilled water 5. Run up to operating temperature and top off Water Wetter and/or with new coolant mix.
