My GT3 is low on coolant and although i'm happy to stick in some general pre mixed stuff, should I be using some kind of Porsche squeezed out of a tropical frog juice or something?

Also, I suppose it is normal for the car to need topping up every now and then? My last car Corvette never seemed to need it, and the one before that TVR spent most of it's time ejecting it out the bonnet as steam. I'm not sure what I should expect of the GT3...

Cheers,

Chris

I get it... you're all just waiting for me to put lime juice in the thing and blow my engine up sky high - thereby destroying the rumour that these engines are unburstable!

Well, i'm not falling for that.... oh no.... i'm holding out for someone to TELL me to put limejuice in it before I do so.

I gave my car a severe caning on Saturday night and the low coolant light came on for the first time, when checked it had lost exactly one litre of coolant.
I'm not sure where it leaked from (header tank or pressure cap perhaps?) but I'll get it pressure tested and topped up with antifreeze before the winter proper sets in

Apparently you do need Porsche approved coolant. I believe it's just red/pink G12 stuff which you can get from VW or even Mobil/Halfords Advance(d) but I'm not sure...

...however, it's a big no-no to use the blue (G11) & mix it though from what I've read.

Hopefully someone more knowledgeable will contribute soon.

Given the value of the car and cost of engine replacement, go the whole hog and buy the freshly squeezed frog juice from your local OPC. That way you will sleep easy at night even though you might have a slightly lighter wallet. No point in skimping on what is truly magnificent piece of automotive engineering.

Just buy the read mix from your dealer, otherwise you'll have to take a sample to check the colour as if you mix the two types together, you get a jelly...

Dan,

I thought anti-freeze was like oil, ie it had to be compatible irrespective of its type or make ?

I was under the impression there were two main formulations in different colours and it was only an issue if you mixed them. Don't think it is nearly as complex as oil. Happy to be corrected on this though.

Thought oil was simple, when I spoke to Castrol technical services about oil for my 964 RS and they said that no matter what the product was, (be it synth, semi synth or mineral) it had to be compatible with any other product on the market (or in your engines sump !) confused

I thought that all coolant types were basically glycol and that the colours were added by manufacturers so you'd know that it had a decent concentration / wasn't just water only?

Ain't no expert by the way...

I heard/read:

Green/blue - G11/glycol based (for cast iron blocks)
Red/pink - G12/organic acid based & phosphate free (for ally blocks).
Purple - G12+ (long life G12?).

G12/G12+ can be mixed but G12(+) should not be mixed with G11.
