*** Torque specs for XI

I just finished a cooling, belts and pensioner overhaul. Finding the specs on the torques for the bolts is PITA.
I tried buying the Bimmertools torque specs card, but unfortunately according to them it's for E46 i's only. Does not cover xi and M series.

I wonder if there is any source to get this info. It would be a lifesaver.

other than the oil pan and front drive train, and Xi is the same as any other e46 so the torque specs are the same.

Bolts are torqued in respect to the type/size of the bolt being tightened not what model of vehicle you drive..... This is an oversimplification and there are other nuances like differeing metals etc. But generally what I said holds true.

In regards to our XIs they will have the same torques as ant other E46 with the exception of some XI specific parts. If you are unable to find specs for the particular part, Torque it by the specs for that size bolt and you will be fine. You are over thinking this.

Hi all -

Just a note, while we were compiling specs for our E46 torque spec, the sources we were referencing had multiple variations for Xi and M cars, presumably due to the variety of parts used from year to year. In contrast, base E46 models had very firm numbers without variation from year to year. This is why we excluded Xi and M from the card.

Our card has specs for suspension, transmission, differential, etc... Many of the fasteners on these components are different on the Xi.

To avoid confusion and liability, I warned mp333 that our card was potentially not going to serve him well.

I hope that clears up our position...

Thanks!

Ken

FWIW, my Bentley contains a chart near the front of the manual listing the torque specs for different bolts, regardless of model. It's something like this:

Correct me here if needed....
The Bentley manual has a Torque chart.
The left column gives you the diameter of the bolt and the column shows the grade of the bolt. You can use a caliper to measure the thread thickness and look at bolt head for the grade. The bolt I was dealing with had 8.8 stamped on it. They were M8 & M10 from the hydraulic tensioner. The torques for these would be 24Nm & 47Nm.
You would basically this info to find the torque using the chart.

Yes. If a specific torque is not mentioned by BMW or Bentley then following the values listed in the chart for the particular combination you are dealing with should be just fine.
