Have any of you used a radiator coolant vacuum refill kit to add coolant after draining it? If so, did it work ok? I'm trying to avoid facing overheating issues afterwards due to air in the coolant system like I did with my Ranger. These were never resolved. The various kits have pretty good reviews, filling sounds easy, and supposedly all or most air is removed. Otherwise, I'll be raising the front end and using the bleed screw (if it exists) and the engine block drain screw discussed in the manual (if I can find them).
