yeah same here. i know caltex sells the compliant GM6277 coolant but id like to find out who makes the genuine one. otherwise tomorrow ill pop into holden and buy 1 litre of it.

I think it is Dex-Cool. Made by Texaco which is Caltex. Both brands of Chevron Global Energy. Used in all GM vechicles post '96. It may come under a different name now as it had a bad reputation for a while for causing corrosion and leakages.

Doesn't sound like a great reason to use "genuine" coolant...
