Porsche coolant, why?

One thing that I discovered was that you really do not want to put any WaterWetter in Porsche coolant. It creates a brown sludge at the meniscus in expansion tank that looks really cruddy (and moreover can look like intermix).

If you are just "Topping off" go buy some distilled H2O and add that.
I'm a big fan of the Zerex G-05 and it is what I recommend to others.
I do have to say, I'm impressed with Rob and his abilities now that he is doing his own work, well done Riad.
/ no I can't edit this.

My head now hurts....but Hey, I am off to Portugal and Spain for two weeks. See ya suckers. I will leave you all to debating the finer ingredients and freezing and boiling properties of our P-Car Coolant.

If you are referring to me, I'm not making or seeking to make anyone to do anything.
I simply offer the advice that when it comes to vital fluid for these cars, to stay with what Porsche recommends/approves.
It is all the wanna be Porsche experts that claim any vital fluid, apparently based on no more than it is *not* approved by Porsche, is superior to any Porsche approved fluids.
And to back it up the people making these recommendations have inches and seconds of testing compared the millions of miles and scores of years of testing Porsche has.
And then they do not of course even back up their advice or recommendations by offering any kind of warranty. It is the advice and recomendation on top of faith and it is faith all the way down.
So, given all of the above, I say stick with the fluids that at least Porsche stands behind for in some cases 8 years and up to 100K miles. Why would anyone want to offer his car up as a guinea pig/test vehicle to qualify in some very limited and rather useless fashion some other brand/type or blend of vital fluids is beyond me.
I recall some years ago Ford produced a vehicle with a manual transmission and the fluid recommended was ATF. This after previous manual 5-speed transmissions came with good old 75w-90 gear oil.
After some time of course the what fluid should I use in my tranny questions came up and of course the 'advice' from the experts was to drain that crummy old ATF out and replace it with 75w-90 gear oil like God intended a manual transmission should have.
Some believed that the only reason for ATF was to reduce the fluid friction to improve gas mileage at the expense of long/trouble free service life, although at that time there were zero or near zero (just the number one would expectf from problems that a new car warranty is intended to cover) tranny failures.
The ATF was there for a good reason. Seems the new transmission had needle bearings in various places that were not well served by that heavier gear oil. Uh oh.
Thank goodness I had the common sense to stick with Ford's transmission fluid recommendation. Oh, 120K plus miles later the tranny with Ford brand ATF in it the whole time -- albeit changed at least once -- was just fine when I sold the car on a few months prior to buying my Boxster.
I see no reason to stray off the reservation 16 years later with any of my Porsches and their vital fluids because I believe Porsche knows as much (at least) about vital fluids for its cars as Ford did back then.
Sincerely,
Macster.

Macster gives some of the best advice on these boards - but many of us are still looking to save a $ by using non Porsche parts - filters, belts, brake pads, rotors, tires - and yes even coolant & ATF.
Porsche sources all these parts from third parties - and I would still argue that a German OE supplier that states they supply Porsche & their product is suitable for Porsche - is OK with me. I would not put in generic Prestone. If you want to go the most conservative route - sure go to the dealer - but I am happy with Mann filters, Continental Belts, Sumitomo Tires, Pentosin fluids, Lubri-Moly etc. I bought a 911 @ 25% of the cost of a new one - I also want to be able to service it at 25% of the cost of a new one !

Rob, I can tell you from experiance that US coolants break down the euro plastic. After seeing this for myself and fixing my 996 I started to use pantosin. (sp?) yes expensive as hell. But it is also meant to last the lifetime of the car. I have a special drain pan that I use if I ever have to remove it as I did to fix the water pump.

Interestingly, I just purchase 2 Gallons of P car coolant at the dealer a couple of weeks ago. The parts department guy asked me, "are you just toping off", I said, "no I'm considering changing my water pump". He said, "ok because we also have a "top off" brand we use that is equivalent that we sell by the pint". I was speachless.

I'm very surprised no one has mentioned the potential problem of non-OEM coolants damaging the plastic water pump impellers. I am not saying that I endorse this opinion but it certainly is a theory bandied about by our resident fear monger.

Do you have to mix the Porsche coolant with distilled water or does it come already mixed?
If the coolant is not already mixed with water then the high price seems a little more reasonable as you'll be adding 50%(depending on how cold it is where you live) distilled water, which is extremely cheap.
Oh, and if it's not already mixed, what brand of distilled water does Porsche recommend?

Porsche is one of, if not the most profitable car companies in the world (% wise). Do you think this has something to do with their markups? I do. I flushed my system and use a good quality coolant designed for aluminum engines. $30 for a gallon of coolant is just crazy.
Many insist on buying parts with Porsche stamped on the box when you can get the exact same part from the same manufacturer for much less. Remember that Porsche sources most of these parts and fluids from other manufacturers.
