COOLANT LEAKING ON IDLE
« on: Jul 28, 2021, 09.37 AM »
Hey Guys, I'm a new owner of a 2019 BMW 7850GS Adventure. done 14500Kms.
I'm having an issue with my bike leaking coolant while its stationary on idle. while i ride there is no issue and no leak. I see that quite a few owners of the 850 had to get their radiators replaced, and i went through the same thing. luckily the local BMW dealership here in Nairobi, Kenya had one and replaced it instantly. seeking out any help or suggestions from the 750/850 family.

Thank you

My bike had the same issue when it was new.
Dealer could not figure out the reason for the leak. It stopped leaking coolant after a few thousand kilometers.

My water pump shaft seal leaked when the bike was new. The pump was replaced under warranty.

There is a small hole under the water pump that will let out any coolant that leaks from the pumps wet side to the dry side through the shaft seal. This is to prevent the bearings swimming in coolant and corroding away.

My 2019 also had a leak behind the radiator. My dealer also fixed it under warranty.

My question is, is this just an issue with 2019, or has it happened with the '20s or '21s?

My dealer told me they only picked it up in the very early models.......
Hopefully they rectified the problem

I have a late 2019 850, never had a problem with the radiator.

I have had no other issues with mine either. I love the bike.

My radiator didn't start leaking until after a couple 2000 mile trips and 18,000 miles on the odometer.

2021 adventure model, water pump started leaking coolant at 7 thousand miles, not good when you ride 950 miles in 22 hours
as you can check the coolant and then ride and realize you're out. 300 miles to the gallon can be a bad thing i guess.
was a fun trip but i forgot about summer time hotel gouging, and didnt bring a tent.
