Does anyone else feel that the plastic cap on top of the expansion tank could do with being a bit stronger ? There is no threaded portion it just seems to clip down ! All my other previous cars had a cap which screwed down very tightly on to the bottle. I would imagine the cap is very prone to 'blowing off'.
Is the standard item OK ? Or is it something that can be or must be changed ?

There's nothing wrong with it.
On your previous cars they a high pressure header tank not an expansion tank.
The screw on cap on a high pressure header tank is in effect the radiator cap.
No high pressure fluid enters the Mitsubishi expansion tank so no it can't blow the cap off.

Ditto to Lee, comes out the cap rather than the drain.
