Antifreeze VALVOLINE or OEM Toyota

Zerex G40 is pretty good. Made by Valvoline and has G12++ spec.

I went with Valvoline Xerex G40. BASF G40 is the equivalent of G12++. Valvoline/ZEREX G40 Euro Pink coolant meets this newest worldwide standard BASF G40 and German standard VW G12++ .

Brands I recommend are of course Toyota OEM Super Long Life coolant and surprisingly Walmart Asian Red Super Long Life coolant (actually comes out pink ) has never failed me and I offer that as an option to my customers. Then there is the Valvoline zerex Asian I don\u2019t highly recommend this coolant but it does work just not that well from my experience.

I have two gallons of this I've used in my 2009 B6 Passat that is leaking coolant. I don't drive it much, just once in a while. I just don't have the funds to fix the leak, which is likely the water pump. This coolant works just fine for me!

for choosing coolant, if just topping off, i use whatever's already inside. so if it's factory coolant, use Toyota OEM coolant.

The green does "work" but it wont help the health of the engine long term as there are chemicals in the Toyota red which help protect the engine, fittings, rad etc. Buy the right stuff from Toyota and it'll last ages, the wrong stuff will screw things up long term.

I did this a few weeks ago on my '13 Sequoia, but I did not flush it. Just drained the rad and the valves on the block. Replaced with Toyota red and distilled water at 50/50. The fluid I drained was as clear as the fluid I replaced, so I felt flushing was not necessary.

I run it in my 2010 Tundra. after much research and not wanting to spend the $$ on overpriced toyota branded coolant I swapped out the system when I hit 100k (Valvoline asian). That was maybe two years ago. 30k miles later no issues.

There's Zerex (Valvoline) Asian car coolant (prediluted) that's made in 2 colors, blue and red, and it's supposed to be compatible

Call Valvoline (Zerex), which makes both green and Asian coolants. Most likely the green you bought is not like the green sold 20 years ago.
