    • Convenient ready-to-use coolant that takes the guesswork out
Size: 50/50
This PEAK 50/50 prediluted antifreeze and coolant is a good option if you want something simple and ready to pour without mixing concentrate with water yourself. I like that it is already blended, especially for quick top-offs or routine maintenance. The biggest benefit is convenience. With some coolant products, you have to make sure the water ratio is right, but this one is already 50/50, so it takes out that extra step. That makes it easier to keep on hand in the garage for cars, trucks, or other vehicles when the coolant level needs attention. I also like that it is labeled for all vehicles and all engine cooling systems. That makes it less stressful when you are trying to pick the right coolant, especially if you have more than one vehicle at home. I would still always check the owner’s manual first, but the broad compatibility is a nice feature. The fluid pours cleanly, works as expected, and gives me confidence that I am using a proper coolant mixture instead of guessing. It is a practical garage item that is worth having around before you actually need it. ... show more

    • Thank goodness.
Size: 50/50
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. ... show more
