Karl as far as I know there is only one bleeder valve and it is located
on the top
left of the radiator. The valve over the engine is a by pass valve. It
purpose is to send water to the radiator by passing the thermostat in
order to get air out and should be be unscrewed counter clockwise until
all air is out. Be careful this plastic valve is very fragile.
