Owner reviews for antifreeze

I have been using Prestone Green FORever, in all my cars but the one that is Dexi-cool. I don't think I have ever had an issue with the Green as I flush my cars on a bi-yearly kinda thing or when I have to change things.

From the manual: "The manufacturer recommends using MOPAR Antifreeze/Coolant 5 Year/100,000 Mile Formula HOAT (Hybrid Organic Additive Technology) or equivalent." Remember that the Routans are really Chryslers in disguise, so no need to go exotic brands on fluids. So you can try this: Valvoline Zerex ZXGO51 G-05 Antifreeze.

Toyota brand coolant is top notch, supposedly can last for the entire life of a car and never needs to be replaced

Do not, under any circumstances, mix generic auto store coolant with G12/13. If you are low, top it up with water - distilled preferably.

Don't switch from conventional antifreeze to Dex-cool unless the cooling system is very, very clean. Otherwise, Dex-cool can dissolve deposits and look like opaque mud. Cleaners used with it can also turn tiny leaks into big ones. Despite this, I've been running Dex-cool in my 1993 Ford and 1986 Toyota for many years, and both cars still have their original radiators and heater cores.

O'reilly around me carries the correct G12. Brand is Pentosin.

I use Prestone Celisus Anti-freeze/coolant. It's pretty much universal, never had a problem in my 92 TD or my 91 1.8 8V with coolant or overheating.

I got the light this morning on the wife's JSW. So I checked out the situation. Sure enough seriously low coolant, like well below minimum fill line. Only 7000 miles. Took it to the dealership to have it topped off.

Volkswagen G12 coolant - ~$20/gallon Prestone Extended Life coolant - ~$8/gallon Distilled water (preferably reverse-osmosis/deionized water)

I've had zero issues using green prestone for the past 100k on my 16v. Just change it every 2-3 years. Car never has any white build-up or any build-up in the hoses, so there's no real reason to not use it. Ph level stays neutral. Engine even has the original water pump at 180k :laugh:
