    It's expensive for this bottle because it's premixed. But mixing your own is a little rough without another container. So buy this bottle and one that's not mixed. Use this one until empty and then pour half of the nondilluted mix. Add water and you have two jugs ready to roll!

    Not worth the money.

    The pre-diluted Dexcool works, and works well, but I never saw the point of paying for water- just buy the undiluted Dexcool and mix it yourself- save some money!

        Comments about Prestone DEX-COOL® 50/50 Prediluted Extended Life Antifreeze/Coolant:

        Pre-mixed is a smart way to buy antifreeze now. Sure, you can buy concentrate and mix it with distilled water - do not use tap water - but that's a lot of extra work. Buy it pre-mixed and you know the concentration is correct and the base water is pure. This is a good product from a reliable supplier along with the convenience of dealing with your local Advance Auto Parts store.

                Premixed with distilled water. Makes it very easy to add or change coolant. On the negative side you could buy distilled water and the pure mixture and it would still be a lot cheaper. Depends on your disposition.

                    its already premixed with distilled water. makes coolant change/flush a tad easier, being its not wise to use non distilled water with dexcool! this isn't your old green stuff.

                      This is the coolant recommended to be used in the owner's manual for my 2001 Chevy Malibu. I try to always buy only this kind since I don't want to mess up anything. It may cost a little more than the store's brand but it's worth it.

                              Comments about Prestone DEX-COOL® 50/50 Prediluted Extended Life Antifreeze/Coolant:

                              GM/SAAB rates this as a lifetime fluid, I've never heard of such a thing. While I did drain the old stuff out and for the most part it appeared clean, antifreeze also has anti corrosives that I cannot quantify just based on how "clean" the fluid looks. In my filler neck there was some flaking of old fluid, so I went ahead and changed it out.

                              I think 6 years is a reasonable time to change a lifetime fluid esp if it is so cheap.

                              The pour-a-bility of these bottles needs to be worked on. Seeing as how the filler neck is 2" wide at most, and most bottles are filled to the brim, pouring starts with even the slightest tilt making aiming a chore. Fix that and you have a winner!

                                  Hi Antonio, my answer to your question on the Prestone DEX-COOL® 50/50 Prediluted Extended Life Antifreeze/Coolant - Part No. AF850 is that you need not to flush the cooling system. With engine cold remove Pressure Cap and fill tank with Prestone® 50/50 Ready-To-Use Prediluted Extended Life Coolant/Antifreeze to cold line. Replace cap securely.
