Pictured here is the engine I have. I want to switch this year and use the quick drain single knob to drain the system then fill it manually with the pick antifreeze. For whatever reason I am always suspect as to how much gets in when I suck it through the intake at the sterndrive. Anyway, was going to drain with know and pull plug on thermostat to make sure water out. Need to know which tube to pull off to fill with pink stuff? I think its the large tube on left of thermostat?
Do I fill it til pink stuff starts coming out of thermostat itself where big tube hooks on? Meaning it has filled the entire block and come full circle? Thanks for the help.
