As a scientist and researcher, DEX-COOL® Extended Life Antifreeze/Coolant by Prestone is a valuable product to maintain engine cooling and prevent heat damage. In older GM vehicles it is required and that sustains vehicle life. Therefore it is a great value. The concentrated version is then diluted 1:1 which offers significant savings and is simple to do. Pour half into empty coolant container and fill each
with clean fresh water. Presto, you have two (2)
Gallons of great PRESTONE coolant.
Dispose of one container properly when done and save one for the future.

I'm telling you for your own good. Switch to the green stuff.

The green is far superior. Yes, you can use it with your aluminum block engine. Yes, you will need to change it more often.

Problem is, when this Dexcool is exposed to oxygen, it coagulates and curdles. Literally, it turns into a disgusting, gunky mud. This is hard to move and creates a lot of pressure against gaskets, hoses, and your engine. Trust me. I have seen the effects on my own Grand Am.

I had to flush the radiator three times because my heater core was literally clogged, and the LIM/UIM gaskets were shot. Also, the DexCool coagulated and got stuck to the t-stat, and it stopped working. This stuff should be illegal, literally. There is nothing good about orange. It's cool, it's what everyone uses, but I use the green in my Pontiac GA '02. You will never catch me using this garbage in my car again. I saw the effects. I tore the engine down.

      I used this to top off when replacing my water pump this month. Great stuff and the old stuff (which is the same) that came out looked like brand new.

          Comments about Prestone DEX-COOL Extended Life Antifreeze/Coolant (1 Gallon):

          Contrary to another review about this stuff turning to mud and clogging up your system; WHEN USED PROPERLY IT WORKS GREAT!! If you want to replace your existing coolant with dexcool you MUST make sure your ENTIRE system (engine, radiator, heater core, etc) is completely flushed of all old coolant that's not compatible with dexcool. Then, I highly recommend using distilled water over tap water when diluting any coolant you choose to use. If you think about it, the manufacturer uses specific products for a reason; and I promise it's not because they just go "hey this sounds cool". They spend thousands upon thousands of dollars doing research to determine what works for thier system. I'm not saying there aren't some great aftermarket products out there. All I'm saying is, if your vehicle requires, or recommends the use of dexcool, I suggest you use it!

                    I read a review where this guy was stating this stuff when exposed to air turns to gunky mud. This will hapopen when it is mixed with another type of coolant that is not compatiable with Dex Cool. That is why you need to refer to your owners manual to see what type of coolant is required for your car/truck/suv. It works great when everything is done properly.

This Prestone DEX-COOL Extended Life Antifreeze/Coolant - Part No. AF888 needs to be mixed 50/50 with distilled water before being used in the cooling system so there is no difference between using that product or the prediluted version. Either of those products would be suitable for use in your vehicle.

                          I have an 2001 Saturn SL2 Base Model Sedan 1.9L engine. Do I need to put the Dex Cool back into the vehicle after an flush/fill or put any other brand back into the vehicle?

                            Hi Casey! I would recommend using either the Prestone Dex-Cool (AF888) or the Prestone Extended Life Antifreeze/Coolant (AF2000) in your 2001 Saturn SL2 Base Model Sedan 1.9L engine. Neither requires flushing the cooling system prior to use.
