Green liquid

Run in service next week. Thoughts on green liquid coming out of this hole on engine? Expected, or stop riding immediately? Thanks

Search water pump

Search water pump and you will find miles of reports. Some stopped, others got water pump replaced.

This small amount of coolant coming out of the weep hole is perfectly normal.
The rule of thumb on GS water pumps is that the pump is good to go unless you have to add coolant to the plastic reservoir which only holds about 3oz.
It is a fairly involved process to change the water pump and something that most owners would not want the dealer to take on unless absolutely necessary.
It is also a very rare event that a water pumps has left a rider stranded.

Here's a picture of my '16 GSA's failed water pump due to the emulsion of both coolent and oil..which I find interesting..BMW recommends using the same contaminated oil not to be replaced with new...

My 2015 hasn't leaked a drop of coolant in 6000 miles of riding. When I took in in for service the dealer asked if I'd seen any leakage, showing me the weep hole. Being a member of this forum I had kept an eve on it.

They said that they had seen "only a handful" that were leaking, mostly 2013 and 2014 model years. They said if I saw anything to being it in for warranty repairs.

BTW, it's not unusual at all for automotive water pumps to weep and leak, it's unusual that they don't. If there isn't a puddle of coolant under the car it 'aint busted. It's a whole lot more obvious when it does it on a bike.

Probably most on here won't experience a water pump most failures are by those doing LD type of riding as I had put in a 6k mile trip this past summer riding in 100f + temps across a multitude of various deserts

You may want to clean it off regularly, unless you don't mind the stain it leaves.

mine drops some drops from now and then, it hasnt dropped any for the past 3 months.
dealer recommended to keep an eye on coolant level, and unless that coolant reservoir is empty they wont replace the pump.

it's normal to weep, but NOT EXCESSIVELY WEEP!.

A leak from this point indicates water bypassing the shaft seal. If it's continuous, get it fixed.

Thanks for all the info. Had the run in service last weekend and they did replace the pump. Said they've been having some issues. Begs the question why didn't bmw replace it before selling it to me, and wasting 3 hours of my time on the best day of the winter at 70 degrees.
