Funny colours in my coolant??


Active Member
When i was racing at the weekend i was checking my water levels and i noticed that theres something in the water? it,s like glitter
greens,pinks, reds?? Water did come out of my exspansion tank twice but i had just connected my heater up again and i was thinking there might have been air trapped in it some where? but don't know where the glitter coloured stuff came from?
Any ideas?


Still waiting on some shims!
The multi colouring could be Oil.. And the glitter could be shavings of metal from your engine!

I'm sure there is a better explaination though..

Possibly oil leaking into the water from the factory oil cooler.

If the glitter is metal, it could either be corrosion or possibly bits of oil cooler (bit of a guess the last one, as not heard of it before, but anything's possible)

Will check it out? The water is still nice and clean (green) but these parts are floating around, very small parts?
