So I decided to do a drain and fill on my 2015 GMC Terrain V6. I had a few Menards rebate coupons so I decided to buy the Coolant there because they sell the Peak Cool orange coolant. However I noticed that when I got home that the bottle no longer has the specific words of it being GM Dexcool approved on in it. It just says for vehicles requiring orange coolant. Other than that the bottle looks identical to the old label that specifically says its for GM vehicles. Even Menards website is still showing the picture of the old label
My Fiesta uses Ford Orange that I have heard is Dexcool but have not been able to prove it to myself. I wonder if this is suppose to take the place of Ford Orange and GM Dexcool, but you would think they would have the Ford and GM specs numbers.
The Peak website says the Orange coolant is for: Chrysler: 2013 and newer Ford: 2011 and newer GM: 1995 and newer but it is a newer looking jug. On O'Reilly's website coolant for a 2015 Terrain they have a similar looking jug to yours but the back of it still lists which manufacturers it is compatible with and DEX-COOL is one of them. It should be ok but it's up to you.

I am not sure coolant color is a good indication of the type of coolant. It would have been nice once they went beyond "ole green" is they had standardized on color and type of coolant.
The most I would trust about color is if I had a Ford that should have Ford orange coolant in it from factory and the coolant in the vehicle was orange, then I assume its Ford orange. But still no guarantee.

Ok so I decided to call Peak since they had a phone number. Technical support said it is suitable to use for DEXCOOl. He said the reason they removed the GM Dexcool wording is because since Ford and Chrysler have adopted an orange coolant they didn't want people to thing their COOL line was only for GM products. That sounds like BS to me, they probably don't want to pay the licensing fee, but either way I now feel safe to use it.
