changing coolant bottle

[Matt e]

when changing the coolant bottle do you have bleed the system? and also when you undo the bleed screw it doesn't need to come out all the way does? just until the coolant starts to leak out?

thanks

I would say you should be fine without bleeding the system, just drain enough out to empty the tank.

If you do bleed it, you just undo the bleed screw until coolant dribbles out.
