Crack in window stool repair

Hello all,

I noticed a crack in the window sil/stool, with one end coming up. Material looks to be PVC. Most of the repairs seem to focus on wood rot, but I wasn't able to find much information on how to correctly perform this repair on cracked PVC in this location. I was initially thinking some sort of PVC filler/glue, but wasn't sure how this would hold up with changing temperatures. Would appreciate any advice/thoughts. Pictures below:

That sill nose looks to be a replaceable piece... it's just shot onto the front of the sill. I would just pry it off and fasten a new piece on. Either wood or pvc.

The stool is the inside trim on top of the sill.

@XSLeeper. Thanks for the quick reply and for the clarification - sill nose was the term I was looking for! Is there a particular reason you would suggest taking it off and fastening a new piece on rather than fixating it (in some way) and/or filling in the gap? The sill nose looks to be one long piece spanning 4 windows, and the break is in the middle.

The break will open and close with the seasons. PVC expands and contracts a lot, more so when painted a dark color. If you don't want to replace it, push it down and nail the left side, then caulk the crack and the top and bottom edges with OSI Quad. It will stick the best to pvc.
