I am in the process of replacing the coolant in my rs250, that I
bought last weekend, with Water Wetter. The owners manual states that
the dealer should do this. I thought that it can't be too difficult.
So I disconnected the hose on the right hand side at the bottom of the
radiator and let the coolant drian out. I re-attached the hose and
began filling the radiator through the over flow catch unit and it
quickly overflowed. I then removed the hose that I had initially
removed to drain the radiator and no coolant came out. The radiator is
empty. I now know that I am clueless here. I did a search on this
forum and only found info on changing a Falco's coolant. I would be
very grateful if someone would please tell me how to properly drain
and replace the coolant. Thanks, Ken
