Just swapped out my Toyota's coolant with Zerex Asian Red and wow - identical performance to OEM at half the price!

The pinkish-red color matches perfectly with my RAV4's factory fill. No weird chemical smells or viscosity differences.

Pro tip: Check your levels when the engine is cold. Mine was low (normal) but after filling, the hot engine brought it right to the proper mark.

Had some initial spillage from the overflow tube during first drive - totally normal as the system purges air. No leaks after that.

5-year/150k mile protection gives me peace of mind. Already bought another jug to keep in the garage!
