As such, if you mix them into the coolant in an engine that is already using a non dexcool coolant, you'll end up screwing up the chemistry of the fluid, and this will always negatively impact the effectiveness of the coolant, ultimately leading it to precipitate early, or potentially reduce their ability to mitigate/prevent corrosion, etc. These coolants are both also good for 5-years or 100,000 miles before they are used up, or risk precipitating out, etc.Īs far as I know, all "universal" coolants are essentially clones of dex-cool, based on the chemicals used to make them what they are. This results in a very specific chemistry for each coolant, or in some cases 'families' of coolants, such as is the case with Mazda FL22 and Motorcraft Premium Gold (G-05) coolants, which are chemically the same, just with different coloration.
However, one thing I can say is that manufacturers utilize a specific chemistry for their coolants based on the physical makeup of their engines, and other associated systems (radiators, etc.), as well as the operating conditions under which their engines run. form corrosive by-products and/or precipitate solids?Ĭan I name one specific example? Not sure about that. Ok, can you give a specific example of where the Napa formula would be chemically incompatible with another coolant, e.g.
It's an Extended/Long Life OAT AF that does NOT contain 2eha. The only universal 'type' AF I would use (with a complete exchange) and am using in a Tacoma is Peak Global Lifetime. Most the spec'd AFs are now readily available as aftermarket AFs. And if it specs DexCool that's what I'd use. Generally I'd choose the type AF the car specs. Personally, it wouldn't be my first choice and unless the vehicle specs Dex Cool I would avoid it. Napa Extended AF has been discussed here before and it is made by Old World, and it's most like if not identical to Peak Long Life AF which contains 2eha. However to get 'extended/long life' interval a complete change needs to be done. Because of their generally neutral color they claim they can be added to most any AF. They all contain 2eha which is major inhibitor found in DexCool. They make up the majority of the AF sold under store names and brand name. Of course, the obvious answer is to stick to the Mopar coolant to avoid issues, but if needed in a pinch, the Mopar coolant can be hard to obtain, since it is only available from a dealer or online.I think you'll find that most if not all the 'Universal Dexclones" OAT AF's make the same claim. I realize I am probably opening a big can of worms, but I was curious if anyone here has any insight into whether or not these are appropriate substitutes for the Mopar coolant.

From what little info I can find online, the Mopar coolant is a silicate free and phosphate free OAT coolant. Both of these are silicate free OAT coolants. Also, Peak has their "Pink" European Car formulation that they claim works in all 1995-present Fiat vehicles. MS-12106, as shown on the Mopar Coolant label. Zerex G30 is marketed as a European car OAT formulation and the product information sheet states that it meets the Fiat Chrysler spec. Recently however, I discovered some products by Zerex and Peak that are starting to appear on the shelves at many chain auto part stores. For the most part, I have been under the impression that this is more or less a unique formulation that doesn't have an equivalent made by another brand. I wanted to bring up the topic of the purple colored 10 year/150K mile Mopar engine coolant that FCA has been using since about 2013 and possible aftermarket alternatives to it.
