I got an oil change yesterday and found out later that the red/orange indicator float in the coolant tank is no longer there. Mechanic doesn't know what happened. I checked thoroughly with a flashlight but it's no where to be found so it's not like I can even wedge it out if stuck. Would it be possible that it somehow went down through the hole?

Can I purchase the float only?
