The radiator flush is fairly simple. You buy a bottle of the flush chemical and the directions are on the back of it. But basically you drain your radiator (and reservoir) pour in the flush chemical and top off with water. Let it run for like 10-15 min with the heater on the highest setting. then drain and run straight water through then fill with 50/50 and devil the reservoir
Never done the power steering though I was wondering about that as well
