You need an OAT coolant. If you can find a generic one for modern Japanese or Euro cars, you can use it. I use Prestone Dexxcool, and get it at Walmart, full strength. Then go over to the grocery dept. and buy .88 gallons of distilled water. It's orange, btw. I don't ever buy premix. Sucker product, paying a bunch of $$ for distilled water.

Burner has a nice Youtube video about what coolant to use. Burner's videos are very worthwhile to watch & learn.

Toyota's is red btw.

You can get away with any brand if it's OAT, but don't mix in the green stuff.
