Looks like 12346290 is the undiluted coolant and 12378390 is a 50/50 premix (50% coolant, 50% distilled water). Both compatible, but if you buy the first one, you are advised to mix it down to 50/50 yourself.

I bought the 50/50 mix because I only needed about 12-16 oz to top off my coolant, if you buy the concentrated and dilute it yourself, use only distilled water to dilute it...

The problem is in (summit racing) they say that #12346290 is also 50/50 , something confusing.
And only the # 12346290 is compatible with Camaro & Corvette. https://www.summitracing.com/parts/ado-10-101 The other Dex-Cool # 12378390 is for Chevy Volt. - And if I put my Camaro VIN or any of my friends Camaro’s VIN (2017-2018 Camaros) the web shop gives me only (12346290) and it’s not clear on the bottle if it’s 50/50 or concentrate. Some people say it’s 50/50 and others say concentrate. Just write # 12378390 in google and see how many Chevy Volt videos. |

As long as it's Dex-Cool it's good for your car. In fact you can buy similar products on eBay or Amazon - all you need to know is that it's Dex-Cool.
In regards to the above products, 12378390 is marked clearly as a 50/50 premix, so that's exactly what it is, whereas 12346290 is undiluted. So either product would be good for your car, just make sure that you prepare a 50/50 solution if you go with the 12346290 one. Hope this helps.

Thanks a lot for the answers, helps a lot.
In fact I ordered #12346290 and I will add distilled water 50water/50coolant. I will see on the back of the gallon packaging if its clear (Concentrate), just to be sure. |

I received the coolant ( Dex-Cool #12346290 = AC-Delco 10-101 ) It is concentrate and it should mix with distilled water 50/50.
On the back side of the gallon wrote on it (Concentrate). Thanks everyone |
