Big Update
Why not use the right tool for the job instead of prybars and hammers around your windshield and on parts that aren't supposed to be hammered or pried? Not trying to be a jerk but you've been held up for how long now because you can't get a wiper arm off? Hope your headgasket isn't leaking. Good luck. ![Sadwavey](https://mbworld.org/forums/images/smilies/sadwavey.gif)

Probably a good idea to replace that y-pipe proactively. That little dot of coolant isn't going to go away and will likely get bigger. Can you see into the hole in your reservoir and if it is opens into the fluid chamber?

its too small to see while shining a light in it. Looked there too when the car was running but to leak signs. Going to the shop for expansion tank today. Will update.

Yeah, shop found absolutely nothing... I would think it could be seeping into the transmission via the radiator, but the radiator was also replaced only 6 months ago! Guess I'm back to topping it off every week!

Check the washer fluid reservoir. If you have the heated package there's a coil that runs through the washer fluid reservoir to keep it was to spray properly when below freezing. It runs coolant through it and mine split. Took forever to figure out where it was disappearing to.
Pop the cap and just smell inside the reservoir. Mine was really obvious. 👍

How difficult is it to replace the y-pipe? I don't mind disassembling the cowl again to get to it, but I couldn't figure out how to get that y-pipe out...
