I think I'll go ahead and change it next weekend (along with a light cleaning of the Mass AirFlow sensor), thank you for your input.

I wouldn't mix anything with the Toyota coolant. If I recall, it is a pretty unique formula that they seem pretty adamant about not mixing any other fluids with it....I could be wrong so read that section in the owners manual or the label on the jug from Toyota.
