I need a comprehensive step by step on how to flush my motor and change my coolant. It sounds easy to many I'm sure, but I need to be sure. I want to drive into Dearborn next Thursday evening (4 hours due east of me) and want to make I get there without overheating. I bought 2 gallons of distilled water, new reproduction upper and lower radiator hoses, cap, heater hoses, thermostat and gasket. I still need to get coolant and a flush kit - (if so reccomended). I'll also need to know the proper amount /ratio of coolant to water mixture as well.
