ACDelco 10-101 DEX-COOL Extended Life Coolant - 1 Gallon

I'm a driver who gets his money's worth from a vehicle and I consider them long-term investments. That's why I follow the manufacturer's recommendations for maintenance and maintenance intervals. If you’re running a GM vehicle that calls for DEX‑COOL, this is the factory‑correct stuff—no weird off‑brand blends, no questionable additives, just the genuine formula designed for these engines.

Worked as it should

cheaper than auto parts stores

After 15 years I decided that I was past due needing to flush the cooling system of my 2010 Corvette. The recommended proper antifreeze is ACDelco DEX-Cool. This product is very expensive compared to other antifreeze, but I believe in using the recommended parts and fluids for my car. It is super important to buy the concentrated fluid, not the 50/50 blend. When you flush the Corvette's system with clean distilled water about half of the flush water stays in the heater core and the engine block. After three flushes with distilled water, to end up with clean water, you fill the system back up with the concentrated DEX-COOL. The combination of the antifreeze and the distilled water in the block and heater core gives you the desired 50/50 dilution in the whole system.

Came fast and I couldn’t find it when I was looking but this is already mixed so you don’t have to add nothing it’s ready to poor into the vehicle.

Good

No issues

Does what it says on the tin

Please note this is the concentrated version. You have to dilute it 50% with deionised water before use. This is not made clear in the product description. You can therefore make up to 2 gallons with the amount supplied.
