I recently bought a 2005 Chrysler Town & Country with the 6 cylinder engine and want to change the anti-freeze myself. I am having trouble trying to find the correct type to use. The owner's manual says to use Mopar brand, of course. However, buying this from the dealer is twice the cost of other brands. It specifies the type must be HOAT (hybrid Organic Additive Technology). Searching this on the Internet only confuses things more. It seems that Prestone claims they have an equivalent, but others dispute that because it is only OAT type. Zerex claims they have a HOAT type which is designated as G-05. That is the only brand I have found claiming the HOAT type. Has anyone else had any experience with finding the correct replacement anti-freeze and do you have any suggestions from your experience changing your anti-freeze on this vehicle? I have changed anti-freeze in other cars before, but not this one.
