Cool!
[This review was collected as part of a promotion.] I used Peak Titanium 50/50 Prediluted Antifreeze and Coolant and have been very impressed with the performance. It was ready to use straight out of the bottle, which made the process quick and hassle free. My engine has been running at a steady temperature.

Super convenient and super easy to use!
[This review was collected as part of a promotion.] I like that it’s pre diluted so there’s no second guessing, making no mistake while making anyone feel confident! Just pour and go! So versatile too as you can use this on any vehicle so I was able to share it with my dad who lives nearby! Easy to transport and easy to pour! It doesn’t have a strong odor.

This product is a great value.
[This review was collected as part of a promotion.] This is a really great product. I used it on my Jeep and my atv. I completely emptied the coolant reservoirs and refilled with Peak titanium. It is already mixed and perfect for most vehicles. After utilizing this both vehicles ran a little cooler than they have in the middle of summer. Very effective and very good product.

Great coolant for your car
[This review was collected as part of a promotion.] Good coolant, used it for a month on my car and everything seems to be running fine. Nothing bad to report. You get a good amount of coolant in each container. Highly recommend!

Use a funnel for Easy Pouring
[This review was collected as part of a promotion.] This bottle of antifreeze was easy to open. When you go to pour it be careful, or use a funnel because it’s hard to pour it into the hole when the bottle is full. Once you get it flowing though, it pours right in easily. Does its job!

Just what I needed!!
[This review was collected as part of a promotion.] I ran out of coolant and the car overheated so this was right on time. The cap wasnt hard to open and the product was easy to use. You can use it free hand but I chose to use a funnel to ensure nothing got wasted!! After letting it sit for a while I started my car back up and everything worked just fine. This was such a life saver!! I’m so glad I had this on hand.

Nice
[This review was collected as part of a promotion.] This came in time to change the coolants in our cars! The packaging is easy to open and to tilt in order to spill the coolant into the car. The instructions were easy to follow

Does its intended purposes very well!
[This review was collected as part of a promotion.] As far as coolant goes, there’s only so much you can really say. This has worked well for me. I used it during a coolant top off and liked that it was already premixed and ready to pour in. The universal compatibility was a nice bonus because I didn’t have to spend time figuring out which specific coolant to buy. If you’re looking for a straightforward coolant that gets the job done and gives a little peace of mind, I’d have no problem using i...

Great product
[This review was collected as part of a promotion.] Used on my car to top of the coolant reservoir. The premixed formula made it very convenient and the bottom is easy to pour it from. No issue after use and the coolant level has remained stable. Would purchase it again.

Does the job.
[This review was collected as part of a promotion.] I have purchased Peak coolant for years. I usually stick with the “long life” version but I figured I would give this a try. I am not a mechanic by any means but I am satisfied with the product. There wasn’t any foam and it was very easy to use. Perfect for an amateur like me that needs to top off levels in our vehicles.

Solid Product, Wrong Tool for the Job
[This review was collected as part of a promotion.] I picked this up thinking it would be fine for my 2024 Silverado. After doing more research, I discovered it’s not the recommended coolant for GM vehicles that require Dex-Cool. I’m holding onto it because it’ll be perfect for my other car when it comes time to flush the radiator. A couple of my mechanic friends highly recommend this coolant, it’s just the wrong tool for the job on my truck. Overall, it seems like a solid product. Just make ...

Great Quality Antifreeze Helps Vehicles Run Well
[This review was collected as part of a promotion.] The Prediluted Antifreeze + Coolant Titanium 50/50 by Peak has been helpful to have for my SUV and van. It has clear and concise instructions.
