I'm about to flush the cooling system and put in new coolant. Two questions;
1) The thermostat has a small popet on the top flat disc - is there a special way the thermostat needs to oriented? What does the popet actually do?
2) The engine block coolant drain plug - not sure which plug this is - I've attached pic with two possibles...
Thanks
