Easy handle and pour
[This review was collected as part of a promotion.] As a cheap and easy solution to have a fix for coolant. No need to mix and the super useful handle on the bottom makes it a lot easier to pour. More bottles need to be made this way!

Easy and reliable go-to coolant and antifreeze that requires no dilution.
[This review was collected as part of a promotion.] It is very convenient that the coolant is pre-diluted and does not need water. It also has antifreeze for those in cold climates as low as -34 Fahrenheit. It is a nice thin fluid that is easy to funnel into the reservoir. No strong odor. The coolant came packaged well and did not leak. I used it in my 2004 Honda Civic which leaks coolant and I frequently top it off. Peak coolant works well. I’ve driven around for about two weeks since topping o...

It also gives me peace of mind knowing it helps protect against overheating and corrosion. The gallon size lasts a long time, and I feel like it's a great value for the price. Another thing I appreciated is that the smell isn't as strong as some other coo
[This review was collected as part of a promotion.] I've been using the PEAK 50/50 Prediluted Antifreeze + Coolant for a while now, and I'm honestly impressed with how convenient and reliable it is.

Most convenient antifreeze
[This review was collected as part of a promotion.] This is the most convenient antifreeze to use. It is already mixed so you don’t have to worry about mixing and getting ratios right. I keep a jug of this in my Tahoe for “just in case”. And the locking cap prevents leaking. I live in the South and it gets really hot. Peak has never let me down! Plus the price is easy on the wallet.

Great product

Classic, True and Timeless
[This review was collected as part of a promotion.] This works good in a 2000's model vehicle. Im not exactly sure about the standards they meet as the bottle doesnt specify but thats the only reason I would do 4 stars instead of 5. Modern vehicles are very picky about the type of coolant with some even taking damage if not correct. You can't beat the price on this stuff .

Peak Coolant
[This review was collected as part of a promotion.] Peak coolant plus antifreeze is amazing. My dad poured it coolant for me, so I don’t have a picture of the after-effect. However, I do have a picture of the before-effect, and you can see on the bottle that it’s already mixed up. This is a plus for me because I don’t have to add any water. I asked him for his rating, and he gave it a 10 out of 10. Since I’m just a girl, I’m also giving it a 10 out of 10. My car is running pretty smooth after.
From PEAK
Highly recommend! Great price.
[This review was collected as part of a promotion.] This has been our go to product for years! The price is great and it works well for all our cars. The coolant is pink. The best part is it is ready to use which makes things quick and easy.

PEAK 50/50 Prediluted Antifreeze + Coolant ~ Recommended, Great Product & Brand
[This review was collected as part of a promotion.] PEAK 50/50 Prediluted Antifreeze + Coolant serves two main purposes in your car's engine: First, it acts as an antifreeze to prevent the water in your engine's cooling system from freezing in cold weather. When water freezes, it expands, which can cause significant damage to engine components. Second, it's a coolant, which helps dissipate the immense heat generated by the engine during operation, keeping it from overheating. Features year-round...
