Intake Manifold Work Flow, Procedures and Torque Specs

The attached procedures are copyright BMWAG. I have not asked for permission to post these procedures: if BMW asks me to remove them, I will.

As mentioned previously, I followed the BMW TIS procedures verbatim, and this worked very well for me. On this page I have separated the tasks into two major headings, Disassembly and Assembly. Within each major heading are sub-tasks. Finally, within each subtask you will find links to each pertinent TIS procedure (all TIS procedures are in PDF format). Detailed notes and photographs appear elsewhere. Note that some procedures call others from within the procedure, so that you only perform a certain number of steps in one before moving to another. The list below follows this calling procedure, and therefore contains duplicate links to the same procedure. The steps to be followed for a given link in the list are noted at the end of each link.

Also note that for reassembly, the same procedures are followed in reverse. This is again noted in each link. The first time a procedure is listed, its full TIS document number is shown: subsequent listings omit this information.

Main Task	Sub-Task	TIS Procedure or Notes
Disassembly
	Battery, etc.	TIS 11 53 325 - Removing and Installing Coolant Manifold TIS 12 00 - Instructions for Disconnecting and Connecting Battery
	Intake Manifold	TIS 11 61 050 - Removing and Installing Intake Manifold, M62 (all steps)
	Coolant Manifold and plumbing
	Valley pan

Assembly	Valley pan
	Coolant manifold and plumbing	TIS 11 53 325 - Removing and Installing Coolant Manifold
	Intake manifold	TIS 11 61 050 - Removing and Installing Intake Manifold, M62
	Coolant fill
	Battery	TIS 12 00 - Instructions for Disconnecting and Connecting Battery
	Coolant flush
	Review work, test drive

I spent six hours on this job, which included several stupid mistakes and one trip to the dealer. Hopefully the information here will allow you to perform this work in five hours or less.

The only BMW-specified torque specifications for the parts involved in this procedure is 22Nm for the intake manifold to head mounting nuts. For all other assembly, rely on your experience and remember that you are working with aluminum components. See the text for additional information.
