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

This was a bit expensive and some other GM Coolants cost less, but always get the full strength coolant and NOT the 50-50 mixes. You'll need tful add 50% water for the full strength varieties. Be cared the coolant you add is compatible with the coolant in the cooling system, because mixing different kinds can cause problems. Always keep your oil and coolant full up and WATCH THE HEAT GAUGE AS YOUR TRAVEL. I believe every drive should be aware that overheating can destroy your engine.

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.

No issues

Great product great price and fast shipping, which beat estimate by four days.

Its the real thing and so far its working

I could not find full strength coolant at any of the auto parts stores in my area. It was great to get it from Amazon

I highly recommend this AC Delco anti freeze. You can't go wrong using GM products.

After purchase sales start but it did it's job.

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.
