Zerex Extended Life Nitrite Free Antifreeze
Today I am reviewing Zerex Extended Life Nitrite Free Heavy Duty (HD) Antifreeze/Coolant 50/50 Prediluted Ready-to-Use 1 Gallon. It is nice to see a product that is specially formulated for diesel engines. It is a pre diluted variety which requires no mixing. It is also nitrate free. It exceeds all requirements for all diesel engines and offers protection from -34 to + 265 degrees. Being an owner of a few diesel engine vehicles myself I will be purchasing this product exclusively. Plus, it carries the proven names of Zerex and Valvoline! I would highly recommend this to others.

Zerex Coolant
Works pretty good at keeping my old girl cool during these hot summer like days. Mixed very well with the coolant I already had in her. I plan on getting more and replacing the coolant/anti freeze with zerex for this winter.

    Looking for coolant for Kubota diesel.
    I was looking for a coolant that meets the factory specs for my Kubota diesel tractor engine. This Zerex extended life nitrite free HD meets the specs SAE J1034 which is listed in the Kubota manual, and it meets SAE J814 as well. Good enough. I drained the old coolant, gave it a flush and a couple rinses, and added the new Zerex coolant. The appearance of the Zerex is yellow, where the original coolant was green. Not sure if that makes a difference. After finishing up, I took the tractor out to warm it up, including climbing a pretty steep hill. It ran cool as normal. I am satisfied that this coolant will do the job in this engine at half the cost of the Kubota factory coolant. Time will tell how it holds up, as for now, I am quite satisfied with this product, and glad to have an aftermarket product that will work in Kubota.

    Good Product
    This is a high quality antifreeze. It is long lasting and compatible with most engines. This should not be mixed with other types of antifreeze. This version is a 50/50 mix so you do not need to add water.

    Keep your truck running longer
    In case you are one of the seven people in the country that has not yet heard the news, the prices of new trucks have gone up significantly. Worse news still is that the prices of used trucks have as much as doubled at the same time. If you are lucky enough to have a truck that works for you today, you want to make sure that you do everything you can to keep it running as long as possible. Changing oil, and tune ups can keep the motor humming, but you need to do you part to keep it cool as well. That's where this Zerex Extended Life coolant comes into play. It's pre-mixed so you don't have to worry about diluting anything. You can keep some in the vehicle to add whenever needed. Just make sure that the coolant in your current system, and they system itself is compatible with this specific Zerex product.

    Simple ready to use coolant.
    I check my 2020 Ford truck fluid levels every month. Most times the coolant is between min and max. When it's below min I add Zerex Extended Life Nitrite Free Heavy Duty (HD) Antifreeze/Coolant 50/50 and don't worry about doing it wrong because it's already mixed and ready to use.

    Great antifreeze
    The Zerex Extended Life Nitrite Free Heavy Duty (HD) Antifreeze/Coolant 50/50 Prediluted Ready-to-Use 1 gallon is a great product. this can be used in cars and trucks including diesel vehicles as well. It's a 50/50 mix which makes it easy to add and takes the guess work out of how much water to add preventing someone from accidently diluting. Make sure you check to see if it's right for your vehicle

    Just what I been looking for
    Needed a heavy duty coolant that was easy to use and nitrite free for my side by side. It's really hot here in Mississippi when you're preparing food plots for the deer season in September. An effective coolant is a must and my SxS recommends nitrite free. So glad to find it - hope it does the job!

    Excellent product
    I have used Zerex products for about 40 years with good results. I have never experienced radiator nor heater core clogs due to antifreeze buildup using Zerex products. I often carry a gallon of 50/50 in my pickup because it is already diluted and ready to use.
