Hi there. Long time lurker - First time posting.
Ive been loosing coolant on my 2015 RR Sport. Within 5-7 days ( about 250-300 miles) it drops to level where I get the Low Coolant warning light, than it seems to stay there for at least 4 weeks. I cant find any leak marks on the ground. Car only has about 50K miles or so, never got hot , so I don't think it would be a head gasket. Any ideas?
Tank you

 

Hey. First off you won’t see anything on the ground because the leak is not a steady flow over a short period of time. Secondly there is an absorbent pad on the faceplate on the floor of the engine bay.
I had a similar issue. Turns out the ‘L’ pipe coming off the water pump is probably where your leak is. Check that out. I replaced mine with a metal pipe from the original black plastic pipe

 

Hey Ternic, where did you find that metal pipe replacement? I'm pretty sure mine is leaking in the same region and would like to upgrade it.

 

Amazon. Less than $20. Keep in mind if you go to the dealership they could knock you up for up to $5000 just for this problem and a lot of ‘things related to this problem’. I was quoted $4800
