They are neat, another bell ! But ! they don't work too good when the system is full of air. The cheapest way to purge the system is to use a squeeze bottle and it can be used to suck air bubbles or push fresh fluid from the bottom. I prefer the pump however as it is good on any vehicle and can suck or push !
