I have an older car an d I use the Peak brand. Its a great brand for Anti freeze. Between Peak and Prestone, from experience Peak is the better brand.

Great price for antifreeze!

Did the job. Would use again.

worked as expected. I cant complain as the price is great.

Having coolent pre-mixed makes it easier to use and instantly available.

Always in my car for emergencies. One of the best coolants out there.

This top leaks and I wasted more than half the product and got this all over my car when I left it sideways

It it not always easy to find this stuff at a good price and to have it delivered was so nice too

I added some to my car and put it in the back in case I actually have a leak and need more urgently. Not to mention, I’d rather not have this super dangerous chemical in the house around my pets! Well, come to find out the child proof cap is only useful when the bottle is upright. Tip it, and it’ll leak EVERYWHERE. I don’t think I’m out of line to expect it to be liquid tight! So now I need to throw out my trunk liner and buy a new one. I would not recommend unless you happen to have a garage or something to store it far away from kids and pets.

Replaced my radiator on my Avalon 2005 I added Peak coolant and it's been working great.

Good price. Good quality.

Great product for your car and truck

Coolant is universal now. Regardless of what people say some tests to different temperatures while others require adding water. APart from that a quality coolant is a quality coolant.

Good product. Good coolant .

great price, will recommend to friends and family.

Great quality and price for this coolant! I own a 2011 Jeep Grand Cherokee with 147k miles! This coolant performs very well during harsh driving conditions. Specially off-road, with heavy engine loads at low speed.

Great price works great in the truck for winter

Great price. Works just as well as more expensive brands.

This product gets good reviews so I thought I'd try it. It has been a few years since I did an antifreeze change in my truck and I simply forgot that I needed full strength antifreeze and not this. The V-6 engine called for almost 3 gallons so I ordered and got three. Where my memory failed me, was that you can typically drain the radiator from a petcock and drain HALF the antifreeze. After flushing with water (heat engine, drain repeat) you have very dilute antifreeze trapped in the engine block, in my case roughly 12%. If you top off the radiator with 50/50, your antifreeze is nowhere near the 50% solution recommended. There are supposedly drain plugs for the engine, but not part of the "handyman's" normal antifreeze change. Perhaps if you want to pay a pro to do this, the 50/50 would be the chosen product. In my case, I needed a gallon of full strength antifreeze since what was trapped in the engine had been diluted by flushing with water. I have not yet checked the solution with a hydrometer, but my understanding proportional math tells me I'm very close to a 50% solution at the end of my effort.
