I just did a coolant change.
It is just a matter of time before that bleeder valve leaks or breaks the plastic housing.
Does anyone know if the newer aluminum thermostat covers will fit the older scoots with plastic? Part #1A011220.

My only concern is the new design has a bleed screw that looks like it would just release coolant all over the front of the engine.
