[This review was collected as part of a promotion.] Have been running this coolant in my 2021 Acura ILX after topping off the reservoir with it a few weeks ago and have had no problems and great performance. Has kept the temperature in the ideal running range and has not resulted in any negative impacts since filling with it. My apologies for the less than ideal picture it was very hard to pour with such a tiny funnel and try using my phone camera at the same time without spilling it everywhere....

Just open and pour in
[This review was collected as part of a promotion.] This is a quality product ready to use no mixing or anything. Perfect product for when you need to do a cooling flush and refill on your vehicle. I will use this product again.

All year round protection for your car's engine.
[This review was collected as part of a promotion.] The 1 gallon bottle of Peak 50/50 antifreeze+coolant provided me with instant year round protection for up to 10+ years and 3000,000 miles guaranteed. The fact it was ready to use allowed me to pour it directing into my car and get back on the go. So far, it has prevented my car from overheating while using my AC, heat, driving short distances and road trips. Great product for my vehicle.

Peak prediluted antifreeze and coolant
[This review was collected as part of a promotion.] It has no foaming to it. It has a slight color to the liquid but nothing too visible. The performance after pouring it in seemed as good as it should be, with no problem. Keep this and all chemicals up away from children and pets.

The product fulfils its function and that is the important thing.
[This review was collected as part of a promotion.] My first time using this product, my car is a 2010 Honda Civic, I think it works quite well, it has a very soft aroma, so it does not bother daily that almost goes unnoticed, and it is also my first time using this brand, I would definitely not discard it the product fulfills its function, the plastic is very resistant so for a climate like the one in Texas in summer it is going wonderful, I think my car supports this brand well for now it is e...

Maintenance made easy!
[This review was collected as part of a promotion.] This is a great and reliable brand! Perfect for year round maintenance and top offs due to the protection it provides against overheating and freezing! It’s also designed to help prevent rust and corrosion inside the cooling system which is a huge plus! One of the biggest pro is that it’s a 50/50 premixed/pre-diluted formula which takes out all the guess work! The cap also has a safety feature to open the container which is great incase you ha...

Works great
[This review was collected as part of a promotion.] We really like this Peak antifreeze and love that it works for all vehicles. It's very convenient that it is a pretty diluted antifreeze and coolant 50/50 mix. We used it on my motorhome and I feel much safer going camping knowing that we won't overheat because we filled up the antifreeze/coolant. We also use this on my daily driving car and it's worked great. I would definitely recommend this brand if you need to buy coolant for your car. It's...
