Review: Hard-to-find, Harder to Afford .... - I have always believed that friends don't let friends buy non-OEM products for their automobiles. Why? because generic non-OEM automobile products are, at best, only 80% accurate to OEM specifications. This AC-Delco antifreeze is for my 1948 GMC Pickup Truck (with a 350 V8) and 1941 Chevrolet (with 235cc). When non-OEM manufacturers make products, they are attempting to copy the OEM's product - which the OEM invented. This is especially true today with computerized automobiles. Any part that interacts with the vehicles computer system must be OEM, otherwise you are asking for trouble. So, why would I spend an outrageous amount of money for something like OEM (AC Delco) antifreeze when I could buy Preston or Walmart brand for a fraction of the cost? Isn't anti-freeze - just anti-freeze? The answer is not as simple as that - but is generally "no". Each manufacturer develops their own brand of antifreeze for a reason. Their engines are tested under the most brutal conditions of heat and cold and from there, the OEM manufactures their antifreeze to work under those conditions to protect the engine from damage. Every manufacturer's engines are different, so one version of antifreeze does not fit all. Because the metals and chemical elements that engines are made from, are all a different combination of steel, iron, aluminum and plastics. This produces different tolerances to heat and cold. Antifreeze must be fashioned for each individual engine. A generic antifreeze will probably work fine under non-severe conditions, but when conditions are severe is when an OEM antifreeze makes a difference. Below zero and above 100F - that is when you want an OEM antifreeze in your cooling system. ## Features - ACDelco DEX-Cool Coolant Antifreeze - 12346290 OEM NEW - ACDelco DEX-Cool Coolant Antifreeze - 0 - 12346290 - 1234-6290 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000QIPS7Q | | Brand | ACDelco | | Customer Reviews | 4.8 4.8 out of 5 stars (725) | | Date First Available | 26 February 2019 | | Item Weight | 4.33 Kilograms | | Item model number | 13 | | Manufacturer Part Number | 34887 | | OEM Part Number | 12346290 | | Product Dimensions | 29.72 x 18.8 x 10.67 cm; 4.33 kg | | Voltage | 12 Volts | ## Images ![General Motors ACDelco DEX-Cool Coolant Antifreeze - 12346290 OEM NEW - Image 1](https://m.media-amazon.com/images/I/51nE1KY47BL.jpg) ## Questions & Answers **Q: Well if this is orange what is the pink and where do you find pink.** A: This is orange because it is 100% pure DEXCOOL from the Jug. When you dilute this with distilled water to 50/50 it becomes pink/red, which is what I put in the car. Check your cars owners manual to be completely sure what coolant and how much dilution you need. **Q: How much will my Silverado hold?** A: CHECK THE HANDBOOK FOR CAPACITIES. SHOULD BE 50% WATEER **Q: Will this coolant work for a 1978 gmc c15 truck?** A: This does NOT go in a 1978 GMC C15 truck. You would need green ethylene glycol. **Q: Will this work on a 1997 chevy camaro z28?** A: If your coolant is orange then yes you need Dex Cool. Haven’t seen a 97 Camaro in a long time some I had my 91 Mustang GT Turbocharged and all the other good stuff playing with all GM Sports Cars. Have to say GM Sports Cars kinda look good in the rear view mirror. Problem is they fade away so fast every time I looked at it. That is long gone now. Viper time. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This product is so cool!(ant) *by J***D on 24 January 2024* This concentrate is the best value for money, it’s stock GM concentrate, just mix with distilled water and gives you 2 jugs of coolant! ### ⭐⭐⭐⭐⭐ Hard-to-find, Harder to Afford .... *by C***C on 24 August 2024* I have always believed that friends don't let friends buy non-OEM products for their automobiles.
