Question GM Dexcool okay as G12 substitute?

Autozone cross references GM Dexcool compatible product by Peak brand antifreeze when punching in antifreeze coolant for the '05 Beetle TDI.

Would it be okay to use a Dexcool compatible antifreeze to top up the G12 antifreeze in the coolant reservoir?

Short of that, where is the best price place to get actual VW G12? Dealer wants around $25 per US gallon.

you may be able to order from IMPEX for a lower final cost.

1. No. Only G12/G12+ and distilled water should go into your cooling system if you like your engine. Dexcool is often referred to as "Dexkill" for a reason. If you just need to top it up a bit, use some distilled water.

2. Check in the regional forums to see if anybody near you has a partial container of it. Most of us get a gallon and it sits around forever since we only need a pint or so at the time unless doing a flush/refill.

But watch that shipping cost! I ordered 4 gallons from them along with a few other small items, and the shipping cost alone was $40 (UPS ground). That's all the way across the country, so YMMV.

If you're nice to your dealer's parts guy and ask politely, he'll probably knock a few bucks off the cost for you--they did this for me when I went in to get some G11 at my local dealer.

You can get the Pentosin product from a few of our preferred vendors. I think it's a 1.5L size.

Mention that you are a member of TDI Club. The dealerships around here give us a 10% discount at the parts counter.

I would never use DexCool again in my life. And, if I bought a vehicle with it, I would flush it out and replace it as soon as I could. The stuff is horrible and there have been a ton of problems with it. Horror stories all over the Internet...as well as my own.

My Corvette once had the orange dexcool, but has long since been flushed and has used green stuff ever since.

Same with our GrandPrix. But I have to wonder if the reason it had problems was someone at IffyLube (where dad liked to take it) topped up the low coolant one day.

The wife's Buick's cooling system is all sludged up and its intake manifold gaskets may be leaking a little. I just may put the green stuff in after flushing it. This great TDI list clued me in to the cause - Dexcool- . Before that I was totally baffled as to what was causing the sludging.

Careful, though, to do a thorough flush out of the orange dexcool-- if the dexcool mixes with green coolant you will really get some gooey stuff.

Thanks for this post. It reminded of a nightmare I had last night where I was accidentally putting green stuff in my Jetta.

I woke up in a cold sweat.

I was also curious about the option of replacing the G12 coolant with something a little more affordable; so, I visited the Prestone website and performed a little research. Prestone indicates that many European car makers recommend phosphate and silicate free coolant, such as G12, due to the mineral content of European water, which has been known to result in heavy corrosion when mixed with this type of coolant. Prestone states that this has not been an issue in the states because our water supplies do not contain this particual combination of minerals; and, as such, recommends their universal coolant (which looks oddly like standard ethylene glycol - AKA the green stuff). My thought is that a proper flush of the cooling system, followed by a switch to standard ethylene glycol coolant might yield acceptable results. Honestly, the engine components (i.e. heads, blocks, hoses, seals, etc) are generally of common material and construction whether foreign or domestic, and the U.S. automakers, like Ford and Chrysler have been using this stuff for years without problems. This being said, I'm still not sure that I'm ready to put my money where my mouth is without further research. I guess we'll find out next month when I replace my leaky radiator and perform the TB/water pump replacement.
