    which antifreeze to use?

    Hi guys,
    My 997S coolant seems to be running low. Do I have to use Porsche brand antifreeze? I have some BMW antifreeze. Do you think they are compatiable?

    Thanks

    05 997S

    The new antifreeze Glysantin G 30-91 EF, Porsche part # 000 043 301 05, is red in color and can be mixed with the old antifreeze Glysantin G 30, part # 000 043 300 88, which is in green color. The new antifreeze must be ordered in future with the part # 000 043 301 05.

    You MUST only use Porsche stuff. Don't mess around. Aluminum has very little resistance to corrosion; hence the strict requirement to use the most compatible stuff which only Porsche makes and approves.

    But you have seen it oxidize. Check out the dull gray appearance of aluminum parts on boats next time you go to one of the Great Lakes. Add to that the erosion effect of hot coolant flowing over the metal's surface, regularly removing the oxide layer, and unprotected aluminum would not be very durable.

    I just use water...

    If you just use a little water to top-up the system between services, you are just diluting the mixture.... shouldn't be a problem.

    If you have add water frequently, you've got a leak which should be fixed before it causes a real problem.

    If you have completely refilled the system with just water, you are also heading for a problem.

    Re: which antifreeze to use?

    If you use water...use distilled water. Tap water can have too much limestone (not sure of my translation..) in it which could ruin your coolant sytem ( if it's only a little bit once , it's fine)

    Aluminum Corrosion Eyeopener

    Don't mess around. HOT fluids are extremely corrosive compared to the same fluid cold.

    I had this little outboard, used in salt water. Every time I used it (not very frequently) I *religiously* flushed it with fresh water from the garden hose. I did this correctly and as I say every time. BTW, I just used the thing for a few hours and then it was flushed and back in the garage.

    Well eventually I had the thing serviced and was astonished at how much the cooling system surfaces had corroded. I expected a good-as-new appearance to the aluminum alloy cooling surfaces. They looked like Fred Flintstones version of an aluminum casting!

    My point: it was amazing how the stuff corroded even with my diligent maintenance. Therefore, regarding aluminum alloys, when Porsche says use their stuff and only their stuff: BELIEVE IT!

    I wouldn't even use water to "just" top off. Just go to the dealer and buy the right stuff.

    It was only to top it up, and I was given that advice here on Rennteam...

    Re: which antifreeze to use?

    ..ok then... I thaught you had only tap water in it....
