I read my owners manual and for my 2007 Jeep Commander Overland with 5.7L HEMI, it was clear that only an antifreeze/coolant that has HOAT composition would be appropriate for topping off the radiator - at least if I didn't want to ruin the anti-corrosion protection of the MOPAR original fluid, and have to completely flush the system later....

Be careful because in the stores the antifreeze/coolant bottles all claim that you can pour their stuff into "any" car, "any" color antifreeze/coolant. But the fine print says "only for short term topping up" and "must completely flush system and top up with fresh coolant" to preserve the anti-corrosion properties of the original fluid. So basically I read these and concluded that it was misleading.

This fluid is a correct replacement for the MOPAR fluid in my vehicle (2007 Jeep Commander Overland with 5.7L HEMI) and will not react with the existing fluid in the vehicle or compromise the long-term protection provided (100K miles between services).

I purchased a gallon of distilled water from a large retailer, and mixed up two gallons from this full strength gallon here. It was a slightly cheaper alternative to purchasing the pre-mixed 50/50 solution that is also offered. I made sure to tightly cap the two bottles and label them so they're not confused with windshield washer fluid or orange juice....

I use G-05 in my '87 Mercedes and '92 Honda. There are at least three types of antifreeze, and before you buy, you need to know which chemistry is correct for your car. I recommend the antifreeze application chart which Zerex publishes. Since Amazon won't allow the link, you will need to Google: "Zerex coolant automotive application chart."

Then, you won't have to ask some kid at an auto parts store, or some random Amazon-Answers dude, what kind of coolant to use.

If, in fact, your car needs G-05 chemistry, this stuff is probably what you want. $13 a gallon with free shipping is a fine deal.

You will also want a gallon of distilled water, available at your supermarket, to mix with the G-05 to get the correct freeze protection.

I called several Auto Zone, Advance Auto Parts, and O'Reilly stores in my area and none of them carried this coolant that is required for my Mercedes C230. Great price and quick shipping with Prime here from Amazon.

This coolant is a nice alternative to the traditional blue BMW coolant. It's relatively inexpensive and also readily available. The fluid is clear in appearance and will take on the color of whatever coolant is already in your system.

I used it when I replaced the cooling system in my BMW, as it is just about the same chemically to the OEM BMW coolant. Works great! The only strange thing about it is that the fluid is clear, so good luck identifying it as coolant if it does leak!

This product is supposed to be equivalent to Motorcraft Premium Gold and it's 2/3 the price, and I did not have to go to the Ford Dealership.

This is right stuff to use when your vehicle recommends using HOAT based antifreeze. It is cheaper and just as good as the more expensive Mopar antifreeze.I used it to replace my antifreeze on my 2006 Jeep Commander after I flushed my system. By the way when doing a complete change out on the Commander cooling system (draining everything including removing the radiator hoses and draining the reserve tank) it takes 14.7 quarts to refill, which means you need to buy 2 gallons of Zerex G-05. You will use about a gallon and a half of the G-05 and the same amount of water to make a 50/50 mix.I highly recommend using distilled water. Distilled water doesn't have impurities or minerals that will eventually clog up your radiator. I bought distilled water for my local drug store for a dollar a gallon. If you doing a simple flush you will probably only need a gallon of G-05 and a gallon of distilled water. When I first started to pour the G-05 it was clear and I thought I had the wrong stuff, but after mixing it with water and after some time past it turned orange.

I found this item for my 2011 Jeep Liberty. This one was only $4 more then the 50/50 mix, which is 1/2 antifreeze and 1/2 distilled water. This product is consentrated antifreeze so you have to pour 1/2 distilled water into the mix. Its a much better buy for you money.
