arieltt Posted September 14, 2005 Report Share Posted September 14, 2005 Hello, In the process of stripping my 03 Gas Gas Pro to change a leaking crank seal I found that the coolant was black and oily. It would seem that my water pump is drinking oil as well. I'm amazed that there was any left in the gearbox. So my question - should I flush the radiator before reassembling the cooling system (and if so, with what?)or just fill up with new coolant? New waterpump seal on its way from BVM.

arieltt Posted September 15, 2005 Author Report Share Posted September 15, 2005 Cheers Heath, O-rings were fine but new ones will be going in. There are a surprising number of o-rings in the Pro engine Just got to check the gearbox works before I box the bottom half up finally.
