    • 🛠️ Reliable Protection for Your Engine – PEAK OET Extended Life Antifreeze is a Game-Changer! 🚗
Size: 50/50
I’m highly impressed with the PEAK OET Extended Life Orange 50/50 Prediluted Antifreeze/Coolant! 🌟 This coolant is designed for North American vehicles, and it delivers exceptional performance in keeping my engine running smoothly, even during the hottest summer days or the coldest winter mornings 🥶. The fact that it’s prediluted means no mixing required—just pour and go, which makes maintenance a breeze ⏳. The extended life formula ensures optimal protection for up to 150,000 miles or 5 years, providing peace of mind that my vehicle is well-protected from overheating and freezing conditions. 🔥❄️ The orange color makes it easy to spot if there’s ever a leak, and I’ve noticed an improvement in my vehicle’s overall cooling performance since switching to this antifreeze. Plus, it’s compatible with a wide range of vehicles, including GM, Ford, and Chrysler models, making it a versatile option for many drivers 🚙. If you want reliable, high-quality antifreeze that offers long-lasting protection for your engine, I highly recommend PEAK OET Extended Life Antifreeze. I’d be excited to test more automotive products from this brand in the future! 🚗💯 ... show more

    • Worked as intended but I used it for my Chevy limited 2016

Might not been the right coolant for my car but did the job as I have a leak 🥲

    • Competitively Priced and Arrived Promptly
Size: 50/50
I switched from the "Dex-Cool" product for my GM auto because I could not locate Dec-Cool on Amazon. This product arrived on time and was competitively priced - - and I could also use it in my Chrysler if I choose to.

    • Exact match in color
Size: 50/50
I needed to top off my antifreeze. Moved to San Francisco Ca about 6 years ago. Haven’t serviced my coolant since I’ve arrived. Don’t drive much but still need to check it. Put on about 2,000 miles in 6 years. 2003 LT silverado has been super reliable since I bought it new in Sept 2002. Just over 120,000 miles now. Engine light came on steady and I thought I had a new head gasket blown. Put in half gallon of 50/50 and light went out. Level is back up to where it is supposed to be. Next month I’ll take it in for a 120,000 mile service specifically for the cooling system, just to make sure. ... show more

    • Perfect alternative to the dealer
Size: 50/50
I swear the manufactures try to make it impossible to find what actually works in your cars. They try and make it so vague that you go to the dealer and shell out over double for the same stuff to top off your coolant. This is the first alternative I've found for my 2015 Jeep Wrangler JK Sport. PEAK puts right on there it's for 2013 and newer Jeep. They specify that it's OAT coolant as required and the big one is that they specify on the back that it is MS-12106 and that's the Mopar 50/50 pre-diluted standard for MS-90032 that is called for in the manual. So you know you are getting the exact same stuff as the dealer if going to sell you. Same color orange as what was already in my Jeep from the factory. Super happy I found this. ... show more
