PEAK All Vehicles 50/50 Prediluted Antifreeze and Coolant for All Engine Cooling Systems, Long-Lasting Yellow Engine Coolant/Antifreeze for Year-Round Engine Protection, 1 Gal.

Works as a prediluted antifreeze and coolant for your car's engine. No need to buy 100% antifreeze/coolant when this product is available and you simply pour it in to your radiator or coolant overflow cannister. I trust the PEAK brand and bought this knowing it just works. I have mixed this product with other coolant and not had an issue with viscosity or heating issues, much less corrosion. It is also competitively priced with consistent quality.

It's 50/50 antifreeze and works. What else can I say.......

Good product at good price

Perfect for what I need, seems of good quality.

At the peak of summer to the peak of winter I find myself very pleased with how well this coolant is keeping my engine performing flawlessly. I really like how there aren’t any dyes in this product so I was able to add it to my car factory coolant. It is a long lasting product that I will continue to use. Not to mention how affordable it is! Thank goodness Peak is looking out for people like me.

For value, Peak is the brand of choice. It is always priced below the competing brands.

Ordered this coolant for the unbeatable price. The same day delivery was a very welcome addition. Used 4 gallons so far. No issues. Tests to -25

Can't find anything better than this product in the market. Please, someone find a way to correct me if I'm wrong. I find the quality to be great, and I have to buy one of these every two month because a small leak in my radiator system, I'm hoping to fix that when I get the chance to do so, but this product so far is allowing me to delay those repair and I just top off the fluids... maybe I'll buy another car instead.
