Easy to use
[This review was collected as part of a promotion.] The bottle is easy to open and pour. It doesn’t get any easier than pre diluted. I have been using Peak coolant since I bought my first car. I trust it, it’s never let me down.

Great brand and reputation
[This review was collected as part of a promotion.] Great product, cost effective, and readily available in most stores! No visible evidence of evaporation or foaming, and did not see sediment in the tank when using. This is a popular brand, and it lives up to the reputation.

Good basic antifreeze and coolant product!
[This review was collected as part of a promotion.] This Peak brand ready to use Antifreeze and Coolant is a nice combo and comes in a gallon sized jug, so it fills up your whole reservoir in one go. We live in the south, so I don't really need the antifreeze but the coolant is a must in the heat. This comes prediluted so theres no guessing on mixing and was easy to pour! Pretty standard jug so naturally there is a little spillage but not much.

Great coolant! Keeps car running smooth
[This review was collected as part of a promotion.] My Mechanic frequently allows me to purchase my own products and pay for labor. Whenever I need coolant, he always recommends this brand. I was super excited to receive it and it keeps my 13 year-old SUV running at a good temperature like it’s supposed to. It’s packaged well and I didn’t experience any leaks!

Reliable Coolant That Gets the Job Done
[This review was collected as part of a promotion.] I recently used PEAK All Vehicles 50/50 Prediluted Antifreeze + Coolant during routine maintenance on my car and was pleased with how easy it was to use. Since it's already premixed, I didn't have to worry about measuring or mixing with water, which saved time and made the process much simpler. The coolant poured cleanly and worked well with my vehicle's cooling system.
From PEAK
It’s antifreeze and coolant
[This review was collected as part of a promotion.] Seems to work well. I don’t know how different it is than others but it is ready to use so easy. There’s no indicator/clear spot on the bottle to see how much is left and the pour is like a regular bottle not easy pour but otherwise it’s simple.
From PEAK
