I am in the middle of the coolant pipes now.
I have removed the alternator, the oil filter housing, air intake stuff.
And need the remove the intake manifold. Once all that is out of the way
it looks fairly easy to swap out the coolant pipes.
My car is 2000 528it and has 160K. The first cooling refresh
was about 80K ago. They did not do the plastic coolant pipes. I now
have a small leak from the upper pipe. I am doing the CCV while in there.
When it is all done I think nearly every trouble spot has been addressed.
If my transmission holds up another 100 K I will be overjoyed.
The previous owner has done 2 transmission filters and fluid so far.
