^^^ This
I replaced my waterpump a couple months ago and didn't get a good seal in one little area and after running for about 5 mins I accumulate 2 small drops at the TDC of the water pump. Nice and orange on pretty new silver, I wasbut it happens. I have yet to fix because it hasn't warmed up enough to really need to given the tiny leak, but you can definitely smell that small amount of coolant when the engine is at Optimal Temps
