Owner reviews for antifreeze

Mb50 Castrol is excellent coolant

I use Peak red concentrate, no probs.

For Coolant OEM Honda the blue stuff is perfect it's almost like it's made for the car.

G13 coolant may be green color too ([Mannol](https://www.mannol.de/products/operating-and-service-fluids/antifreeze-and-coolants/mannol-coolant-g14)) ;)

I’ve checked several types because I live in hot weather country and car engine thermostat is tuned to 105C. I found that ROWE coolant boiling point is 170C which is much higher then others and I’ve been using only that since then and it’s handling 10/10.

I used the ravenol. Zero issues so far.

Castrol hysol mb-50

First used it at college. Liked it so much i convinced my boss to use it at work.

I put purple in my 2015.

I'm the kind of person who uses 100% OEM whenever possible, but I wasn't actually able to find OEM G13. Not sure who the OEM even is.

The purple "Peak" brand coolant in your image is the only kind I was able to find. I've got about 10,000 miles on it and it's been just fine so far.

I use the orange dexcool stuff found at most auto parts stores. I think it's prestone, but I don't remember

Like all the other Malibus of this generation, GM sent this one out into the world filled with Dex-Cool, a long-life coolant the color of vodka and grenadine. Dex-Cool was supposed to up the coolant change interval to at least 100,000 miles, and prevent corrosion better, and generally be a better choice for aluminum parts than the green-death ethylene glycol antifreeze that we're all used to. Dex-Cool also had the added bonus of liquefying silicone rubber, which unfortunately was the material that GM used to seal the coolant passages between the heads the intake manifold.
