After testing Zerex Asian Red in my Toyota RAV4, I can confidently say it performs just like OEM coolant at half the price. The pinkish-red color matched perfectly, and the viscosity felt identical when pouring.

What impressed me most was how it handled temperature changes. When my engine was cold, the level sat at LOW (as expected), but after a drive, it rose to FULL without any issues. The overflow tube worked exactly as designed - a few spills initially, but that's normal system adjustment.

The silicate-free formula gives me peace of mind knowing it won't cause buildup in my cooling system. I've put about 3,000 miles since switching with zero temperature fluctuations or leaks.

Pro tip: Always check your levels on a cold engine! I learned this the hard way when I initially panicked about 'low' coolant that was actually at proper levels when cold.

For Asian vehicle owners, this is hands-down the best value alternative to dealership coolant. I'll never pay OEM prices again now that I've found this equivalent performer.
