Folks, I looked under the hood of my 2013 Lexus GS 350 F Sport and there's a pinkish materials on the front most reservoir right in the center of the vehicle. It's bubbled up outside of the cap and seems to have formed a crust of sorts.

Any ideas which fluid this is?

Its coolant/antifreeze fluid. Just make sure the cap is tightened properly (after the car is cool of course). It's likely just a little overflow that spilled out. I, as well as a few others, have seen this.

Thanks. I'll check that out.
