Changed the coolant during a valve inspection. The thermostat is now burping coolant into the over flow hose. Very little coolant displaced.
Does the 570 have a coolant bleeder somewhere?
With the cap off the coolant comes up and over the openning when hot.
Perhaps the rad cap needs replacement or was not put on properly. I drain the coolant too when doing valve inspections and do not perform a bleeding etc. So far I have not experienced any surprises such as yours...
