Hi,

Sorry, distilled water is water which is boiled, or otherwise evaporated, to vapor which is captured and recondensed into a liquid. All Minerals and other impurities are left behind in this process.

Leaving Tap Water sit for 24 Hrs. will de-Chlorinate it (the Chlorine will evaporate away), but hard minerals like Calcium, Lime, and Metals will remain and you don't want these in your cooling system...

I went to a local GoodYear, and they quoted $100 for the radiator flush + the cost of the coolant which I have to provide. I haven't found any of the recommended coolants in my Texas town (not pepboys, autozone, walmart, napa). Order online?

They use a "BG" flushing system(http://www.bg-international.net/?categoryId=1898). Does anyone know what that entails and if it is okay for a porsche?

Thanks!

I have the same question; does ANYONE out there have any experience/advice/opinions on the use of the power fluid exchange system (BG does seem to be the largest supplier) on their 986/996 cooling systems?

There is a flush component to the power exchange, prior to the replacement of the new coolant. To me this system seems to be the most efficient and thorough method, as well as knowing that the old fluid is properly disposed of. But doing any harm outweighs any possible benefits, in the way of efficiency, thoroughness, PC disposal, etc.

Shops in my area are offering the BG extration/flush/replacement fo $85 + or - a few bucks. I assume that the substitution of the Extended Life Zerex or whichever of the products that Jim has listed; would add to that cost.

I'd like to do or have this done soon, so any replies will be appreciated.

I'm using this, about $12 a gallon at Wally World:

Thanks Paul,
But I'm trying to find out "How", as "What" has been covered....

I just don't want do do any damage via the use of the power extraction-flush-replacement service, as there are so many "unique features" on our cars; that many years of experience and common automotive sense, just don't seem to apply, sometimes...

A great example would be that there's only ONE brand, ONE type, and ONE p/n of ATF to use without damaging these goofy little ZF 5HP-19 trans units, that are the Tiptronics.... (and whatever Audi, Jaguar and several others use).

Another board member used a similar system at his father's shop without incident (well almost, he used the wrong coolant).


I do most everything myself, so all I need is the antifreeze and distilled water. It is easy to do, just takes time (probably as much as driving to the dealer, waiting for it to be done and driving home).

My way, less than $45 (3 gallons of each).
