I try to be neat. Maybe others are just opening up the housing and letting coolant spill out and then hosing down the front of the motor.

Some is going to spill no matter what.

Understood that I would have to deal with some spill. If i just siphon out whatever I can and then refill without touch the bleed screw would I be fine?
