preferred coolant

[jimmyone]

just got myself a 3.2 boxster,
i put the pink halfords O.A.T.(Organic acid technology )in my jag, as recommended in the Jag handbook
but cant see anything recommended in my Porsche handbook !!!
ive been told the wrong coolant can corrode the solder/ brazing on the rad ?
any advice on engine coolent would be appreciated
thank you

My 911 was specified with the same OAT coolant - I'd imagine the Box is the same.
