I'm planning to do a coolant drain and fill on my 06' TSX.

Prior to draining the coolant, you are supposed to have the climate control turn to HIGH to let the coolant drain from the heater block.

After draining I need to bleed the air out of the system and have the engine warm up so that radiator fan cycles 2x.

My question is...during the air bleeding process, do I need to have the climate control on HIGH or leave it off? Would anyone suggest using a spill free funnel? or just do it with a loose radiator cap?

Thanks in advance!
