Is this the dreaded leak?

Just noticed what appears to be a coolant leak. Is this the beginnings of the dreaded condition that makes the engine grenade itself?

probably need to be a little more specific ...is it coming from the radiator or cylinder head or reservoir.....could be a loose hose.

Looking at my picture, it looks like it's coming from where the top meets the bottom of that funky reservoir the radiator hose
leak.webp
connects to. Is that seam a known failure point? What causes it? It's never ran hot.
 
the plastic coolant fill reservoir with the metal cap is leaking. You can change it. They are known to leak after certain time.
Are you in a hot climate?

ps. No its not the dreaded engine coolant leak on the Turbo.
 
My 19 Reserve's reservoir doesn't look like that. Was the original replaced somewhere along the line.

I'm in SoCal.
A few 100 degree days in the summer.
Not too terrible. She's never appeared to run hot, according to the gauge.
Thanks, glad to hear it's not a catastrophic issue. I'll get a new reservoir.
