Engine + Driveline / M42 coolan pipe replacement

« on: May 12, 2011, 09:36:19 PM »

Hi Everyone,  I need to replace the coolant pipe on my 1994 318is.  I will get one at the local dealer.  I talked to the parts person at the dealer and he thought that I needed to take off the upper intake manifold along with the throttle body in order to replace the coolant pipe, but that I could leave the lower intake manifold attached to the engine block.  Can anyone confirm this, or offer any other tips on replacing the coolant pipe (bty, a new one at the dealer is $30).  Thanks for any advice you can offer!
