Go down to the local VW/ Audi store for a couple of jugs of this:

 

Malcolm,
I am all ears - why?

Very funny....that stuff is for Volkswagens which are air cooled

That's exactly the stuff I got when I went to the Porsche dealership the first time I got my car. It is also good for aluminum engines.

 

Dexcool is only meant to go into cars that left the factory with Dexcool in them. If it is mixed even a little with conventional coolant, it will start gelling up and doing nasty stuff. Also, if it sees open air for too long, it will start crusting up (not really a problem on 928s). How sure are you that you have flushed every drop of coolant out of every crevice in the entire cooling system? G-05 also lasts 5 years and is fully compatible with conventional coolants. Because of this, to me it is a no-brainer to go with G-05.

Oh boy, Mark should be here in about 5 minutes.......

 

This is the OEM coolant used in Porsches..............its blue in colour and is the coolant of choice in my 928.

 

Coolant for an air cooled engine..............now thats funny Little early for the sauce HP?

 

Btw, I now use Glysantin, made by BASF. I think it was developed together with Vavoline, so I assume it is the same as Zerex. Now, I use Glysantin G48, which is low silicate and phosphate free. It is recommended for o.a. older Porsche aluminun engines (924, 928,944, 968). Funny thing, Glysantin also comes in G30 Alu protect, which is both silicate and phosphate free. That however is recommended for newer Porsche models. Glysantin G05 is supposedly good for grey iron cast engines (whatever those are). So, if Glysantin is the same stuff as Zerex, don't you guys have G48 in the US?

 

I just got a gal of the audi coolant for my wife's A8, it is red. will have to check the number on the bottle and compare to Malcolm's pic.

I decided to drain my coolant and replace when changing hoses because I had no idea what the PO had usesd. does that Audi coolant cause any issues if there is a small amount of old coolant in my car?

 

Earl,
What is wrong with Dex-cool?
If it is not good for some reason I would like to know please?
Roger

 

I heard to use the Prestone "Orange"?

 

Apparently it's not meant to go into them either:

Am I the only one who calls up auto parts stores and asks for an upper radiator hose for a 1965 VW Beetle or a 1986 Porsche 911?

I didn't realize Dexcool was the name for the awful coolant that comes in GM vehicles. I've been hearing horror stories from mechanics I know about that stuff.
