All, ,this is a picture of my '10 Mini-S front end with a small leak... 1st picture is a picture of the whole front end.... 2nd picture is specifically where the leak is... is this a heat exchanger pipe leak? is this something that is an easy fix? looks to me like if i can get down there, I could tighten the pipe to stop the leak... and it's a very small leak, it just smells alittle to be aware of... thoughts? Thanks in advance!

Thats the coolant line, it looks to be on the fitting and not the copper crush washer? Number 10

Goes to the aux water pump.

is that difficult to replace?

Its easy from the bottom and then on the top nut, not too bad. Easier to get to the aux water pump from the side or bottom near the oil filter housing.
