Description
Zerex from Valvoline is the #1 selling OEM-approved coolant brand. Zerex G40 Antifreeze/Coolant is proven to maximize engine life in cars and light trucks. It’s the premium carboxylate formulation recommended for BMW, Mercedes-Benz, Porsche and VW cars and light trucks, as well as older Audi and Volvo vehicles. Specially formulated with state-of-the-art Si-Organic Acid Technology (Si-OAT) in an ethylene glycol base, Zerex is made for your car and protects better than industry standards against corrosion, leaking, deposits as well as freezing and boiling – the four main causes of cooling system failure, which is the leading cause of engine breakdown. Our premium grade long-life Si-OAT formula is nitrite, amine and phosphate-free. It protects from corrosion, scale and rust, so radiators, water pumps and other metal cooling system parts (including aluminum) stay clean and your antifreeze flows and functions properly. Zerex G40 Antifreeze/Coolant contains no imidazole, borates or nitrates. So whether you’re topping off your radiator or doing a complete system flush, trust Zerex G40 Antifreeze/Coolant. Made for your car. Made by Valvoline.

G12/13 compatible, identical to the G12++.
[This review was collected as part of a promotion.] From what I've been able to find out with research online, this G40 coolant is almost identical to the G12++. I recently changed my timing belt and coolant pump, and after a flush, refilled with the G13 Pentosin (purple), and this is compatible with that coolant. I knocked off a star because I understand the convenience of the 50/50 blends, but I hate the fact that I'm paying close to the same price per gallon for half the coolant.

Awesome formula
[This review was collected as part of a promotion.] Superb formula! And ready to go, with no dilution required. My car definitely needed a little boost and this came at the perfect time! I tend to manage a steady upkeep with my car, so this antifreeze/ coolant is definitely worth it. I appreciate how big this container is.

Good stuff
[This review was collected as part of a promotion.] Not sure what to say. This coolant did its job like it was supposed to. It did seem more expensive than necessary. I would recommend to a friend. I couldn't tell a difference from traditional coolant.

Made just for my car
[This review was collected as part of a promotion.] Valvoline has always been a company that I use and trust for auto oil. I’m not sure if I even knew they made an antifreeze but I will be using this product going forward. This blend is specifically for VW which I recently purchased and that is awesome. Knowing that it is for my specific car makes me feel comfortable. I highly recommend this product.

Best antifreeze for older Audi

Great Zerex Z Coolant
[This review was collected as part of a promotion.] I received this Zerex G40 Phosphate & Nitrite Free 50/50 Ready-to- use Antifreeze/ Coolant 1 Gallon from Influenster free in exchange for my honest review. I used this Zerex G40 Phosphate & Nitrite Free 50/50 Ready-to- use Antifreeze/ Coolant in my vehicle and noticed the temperature is much lower. I like that I don't have to add water to the mixture. It's already diluted and can easily be poured into the engine Coolant reservoir. It's made in the USA and specifically made for my vehicle. I was able to fill up my reservoir and still have plenty left over for another time. I'm am pleased that it has rust and corrosion protection. This Zerex G40 Phosphate & Nitrite Free 50/50 Ready-to- use Antifreeze/ Coolant has been a great addition to my vehicle, and now I'm completely protected during the summer and winter months.
