I should have a jack and stands or even ramps but I don't. And I don't want to go to mr lube. I need to flush her from above, my plan was to unbolt the thermostat housing and remove the lower rad hose, and flush it out that way by pouring water from the top thermostat opening, will that flush the coolant from the engine it out? The rad is the easy part. I was gonna disconnect the heater core hoses as well and flush them? Does that about do it?
