Noticed gunk on the water pump weep hole when I was under the car looking up into the engine bay. Pic is from under the engine bay. Its got 31k miles and I've never touched or topped off any coolant since I got it from the dealership. Model year 2025. No low coolant warning. Not sure if its coolant residue or something else. Rest of the engine bay looks clean, nothing on the belt or the splash shield/undertray. Should I be worried?https://ibb.co/ynv7zys2

Image ??. If it's wet and forming a drop/drip from the pump seal weep hole then the seal is "on the way out" Might last months or less. Hard to say. There are approx 20,000 drops of water in a litre so even losing 100ml of coolant going to be a 2000 drop mess so it's not about the leakage rate currently I'd say but the potential timing of the future failure.
