I'm not completely opposed to the block drain, it just didn't sound like an easy thing to access and its not really clear to me the best way to do it. How difficult is it to remove and reinstall/torque the block drain plugs while laying under the car? Is there risk of damaging them and should I buy replacement plugs? Does anyone know the torque spec? Also what size drain pan would I need to avoid splashing coolant all over the garage floor? Maybe I'm overthinking it and need to just try it amd see how it goes...
