Hey guys I just wanted to clarify a few things, I have a reasonable understanding of how a motor works and now I have a better understanding of how the cooling system works on a 7m, I think I’ve read nearly every post on this forum on the dreaded BHG and the cooling system :).
In the past I’ve...
Hey I could be wrong, it wouldnt be the first time. Maybe I have been a bit too quick to call BHG. Lucky it's not my daily driver so I can take my time and check it out a bit more and I think I will do a leak down test just to put my mind at rest. Thanks for the help
