Ford use a 70/30 mix, they all do it, mine is at 13k now and is brown, going to drop it and do a nice 50/50 mix of Nulon today.

its manual.

yea I really wanna piss it off! 50/50 meaning 50water 50coolant?

[JET-270]

Yeah 50% demineralised water 50% coolant. I always fill the rad up with a bit of clean tap water and run the car on idle for a few minutes to get rid of all the coolant in the block.

Funny how they do this, I have a new car now and it's done 70,000km and the coolant is crystal clear pink and it's the factory fill...

Maybe it's a reaction because of minerals alloy head iron block and extreme heat from turbo... I dunno

yea I thought it could of been just a colour change from the engine temps

thanks for the info guys

Check for exhaust gases in your coolent when running. If your really unlucky your head gasket may be on its way out

Have you tried just syringing the top crap out of the overflow and topping up?
