Is it Broken Y tube again on 2014 gl450?
Just got the tank back from service after getting coolant, brake and tranny flush, came home and found tiny drip in front left side, this has happened before and the Y split tube that carries coolant was leaking and replaced under warranty 4 years ago, there are some signs of overflow on the coolant holder and not sure if that is dripping down or the Y tube broke again, kept an eye on it and after 10 minutes it's still drips, the last time it happened I was able to see very tiny spray from the Y tube region but I can't seem to locate that now, is this something I can fix once engine cools down and how easy is it? After looking further leaks seems to be coming from the white plastic thingy inside driver side front wheel well, what is that part?

See the following 2 posts and check the fluid to confirm what it is: Coolant or Washer Fluid.
If washer fluid, it could be the washer pump leaking or the reservoir is cracked and leaking.

If Coolant, you will have to further investigate where the leak is coming from.
