Vauxhall Combo 1.3CDTI Cylinder Torque Settings

[stumas85]

Hey All

Joined today to see if anyone can help me and a friend with the cylinder head torque settings for a 2012 Vauxhall combo 1.3cdti with engine code A13FD

A picture of the diagram with the torque for each bolt and sequence would be excellent.

Thanks in advance to all.

Tightening sequence is the same for all engines. Start in the middle and work out diagonally doing all the bolts up a bit at a time sequentially in stages. Never do one bolt up fully before getting to the others. Torque settings were not immediately apparent on google but 40 ft lbs and then two more turns of 90 degrees each cropped up. Not sure if that was your exact engine though so check with a workshop manual or phone a main dealer.

Personally I don't use book torque settings. I calculate them myself from engineering first principles but that's way more than you're wanting to learn. If it's 10 mm grade 10.9 stretch bolts which is my best guess for a little engine like this then I'd use 25 ft lbs, then 50 ft lbs and then an additional 45 degrees. Lightly oil the threads and under the bolt heads. Make sure each bolt screws cleanly into the block by hand before fitting them.

If they are 11 mm grade 10.9 stretch bolts I'd use 30 ft lbs, then 60 ft lbs then an additional 45 degrees. The grade should be stamped on the bolt head. The thread diameter you can measure with vernier calipers.
