    Its probably been run on crap coolant, vaux V6's need red coolant as there is an anti corrosion additive in it to prevent the water jacket mounted cooler rotting through and failing!


    Btw, ALL GSi's are msd's, doesnt mean anything, just means its a GSi

    What was the oil like that came out? Usually when the oil cooler goes it pushes the oil into the coolant.which in turn pours out the expansion tank.

    I think it should be the same stuff yes, but if its not a million quid then id go for GM stuff as that definately has the anti corrosion stuff in it, its only because they were dumb in being clever and mounted the thing that makes the oil colder, and in turn gets hot itself, in the water jacket thats supposed to cool the engine!
