Pretty good antifreeze
[This review was collected as part of a promotion.] This is a pretty great antifreeze product to use on my 2025 Buick Envista. There was plenty of a jug to use and then have some for next time I need it. This definitely save me money in a long run. The delusion is a perfect mix. My vehicle is performing great.

No need to add water!
[This review was collected as part of a promotion.] This product is easy to use. You don't have to mix it with water. It's easy to open, but I wish it was nicer to pour. A funnel top or something would make it easier to aim. The product does its job well though and I haven't had any issues with my vehicle.

Worked well in my older vehicle
[This review was collected as part of a promotion.] Worked well in my older vehicle! Before trying Peak I was just using a store generic. I can definitely tell a difference with the higher quality product.
From PEAK
Thin consistency
[This review was collected as part of a promotion.] This coolant is okay for the price. It does what it’s supposed to do but the liquid seems a lot thinner than I expected. It’s not bad, just pretty average. If you’re looking for a budget friendly option, it might be worth trying.

Good for car health
[This review was collected as part of a promotion.] It is hard to tell how good it is on this you test it in the freeze. But as my research, it looks to be really healthy for my cars Life. I have three cars so this was really needed in the long-term. It protects the engine and also my mechanic advised me to use this. Especially this is the truth for aged cars.

Great, easy straightforward product
[This review was collected as part of a promotion.] Great product. The premixed formula is nice and easy so there's no mixing and measuring involved. Great for a top off of antifreeze. Bummed it wasn't a bright pretty color but oh well!

Great choice antifreeze + coolant
[This review was collected as part of a promotion.] This coolant/antifreeze is a reputable brand and made for all vehicles. It is made to protect the engine as well as from rust and corrosion. It comes pre-diluted so very easy to use- just pour it in and top it off. My car runs great so I think it is helping. Lid stays on securely so I can leave it in my trunk without the risk of leakage.

Reliable, easy-to-use coolant with great packaging, safe premixed convenience, and dependable performance
[This review was collected as part of a promotion.] I’ve been very impressed with PEAK antifreeze. The packaging is sturdy and easy to handle, with a secure cap that prevents leaks during storage and use. The consistency is exactly what you’d expect from a premixed coolant, making it simple to pour without guesswork. The appearance is clean and professional, and the fluid itself looks high quality. I would confidently recommend it to anyone looking for a reliable coolant solution

Reliable and effective!
[This review was collected as part of a promotion.] This product was used on a bmw. The 50/50 diluted mixture made it very easy to top it off and not having to do any extra steps. It mixed fine with the existing fluid in the vehicle, and the engine temperature has stayed steady. The packaging itself is pretty easy to use, but when it’s totally full you can definitely spill some of it when trying to fill your vehicle with it. That’s okay because it was a pretty easy cleanup. It has been a reliabl...

Great product to keep your vehicle cool
[This review was collected as part of a promotion.] It is a great product to help keep your air conditioner nice and cool during the summer. It is easy to use. You just pour it directly into your vehicle, and it is good to go. It is a large amount for a great price. The consistency is very thin, like a liquid. It works fast!
From PEAK
Perfect
[This review was collected as part of a promotion.] This is perfect for top offs! I have used this to top off all my vehicles, my car, my wife's sedan, and my truck I use on the weekends. It works for all makes and models which is perfect for me and my family. I love it being year round protection, since the temps can vary so much around here.
From PEAK
Best antifreeze!
[This review was collected as part of a promotion.] My husband loves the anti freeze. He was super excited to get it. He feels it’s one of the best. It’s a 50/50 ratio so no mixing required and it’s recommended for all vehicles. It’s easy for anyone to use to perform light maintenance on your vehicle. It keeps the engine running perfectly.

Okay. Great price
[This review was collected as part of a promotion.] It would not allow me to add more than one picture! I tried several times to add photos of us adding it to our vehicles Now for the review The price is great, however that does make me skeptical. We put it in all 3 of our vehicles and no issues yet. I will say the packaging is lacking .upon opening it seemed to come out wayyy to fast

PEAK!
[This review was collected as part of a promotion.] Nice durable packaging. We have a pretty old commuter car that we’re try to keep going as long as possible and this has kept things from getting too hot and from getting too cold. We have not had any issues in the hot Carolina heat with the car and we owe that to PEAK. This is keeping our vehicle maintained and because it is premixed it makes putting it in or installing it easy.
From PEAK
