Mixed a little Pink coolant into Red, drain required?

[89FourRunner]

I am really anal about this stuff, but when i did some recent work on my 89 4runner it required a coolant top off. My friend who was helping me claimed he had plenty of toyota coolant on hand in his shop, and began adding coolant to my rad that I spotted was PINK not RED. So i immediately stopped him but he probabbly already added about 12oz or so. I had him stop and procede with the RED coolant I already had.

Now - I'm not made of money, nor do i want to drain the entire cooling system here....am i screwed? I am willing to bet Pink is a no no mixed with red?

It was only like 12oz or 16oz tops by the time I realized the mistake. Can life go on or do I need to drain and refill?

I'm willing to bet the pink was Zerex Asian, and it's fine to mix with Toyota red.

The pink was actually drained and kept from a rav4 with like 15,000 miles on it haha - so it was in non-labeled bottles.

But you are correct. I was able to dig this up:

So it would seem the Pink super long life stuff is the same as the red. A little extra digging and I also learned that Toyota switched to pink dye in their pre-diluted coolant, as oppose to red in the concentrate, but they are compatible and the same, despite the pink having a longer factory fill service interval.
