SOURCE: Torque and sequence to Intake Manifold for 3.3L Nissan Xterra 2000
Hi El Faraon,
I believe that you're dealing with 12 mm bolts and nuts....THESE ARE NOT THE SPECS FOR YOUR ENGINE, but I believe that if you use them you'll be close....Tighten in three stages up to 22nm....choose the bolts from the centre of the manifold and circle outwards until you reach the last one.....It may be a good idea to draw an overhead or plan view of the unit, marking out the bolt positions.....Start at the centre and mark the sequence and follow that....What is important is starting at the centre, so that nothing becomes warped....
Hope this helps,
Regards, Johngee10
