Torque specifications
Hello everyone. I'm in the process of replacing my engine and I'm having trouble finding torque specs for the following items drive shaft bolts, exhaust manifold (header) bolts, power steering, alternator, starter,tensioner pulley, ac compressor, transmission bolts if anyone has any of this information it would be a huge help as I'm currently at a stand still until I get the information thanks in advance and I may ask for more specs in future
Have you checked the factory manual? All of that information is there. G37 Factory Shop Manual
That said:
Driveshaft: 55ft./lb.
Exhaust Manifold: studs 11ft./lb.
Exhaust Manifold: nuts 22ft./lb.
Power Steering Pump: Upper 27ft./lb.
Power Steering Pump: Lower 35ft./lb.
Alternator: Upper: 48ft./lb.
Alternator: Lower: 21ft./lb.
Starter: both bolts at 35ft./lb.
Tensioner: 41ft./lbs. (Idler pulleys at 21ft./lbs each).
A/C Compressor: all three bolts at 23ft./lb.
For the transmission you will have to check that for yourself. There is a specific sequence that has to be followed and that sequence varies whether you have the 6MT or 5/7AT unit.
DISCLAIMER: above torque values were taken from the 2008 G37 Coupe FSM. Values should not vary between years and body style, but it is your responsibility to verify these specifications as they apply TO YOUR SPECIFIC CAR!
Again, all of the info you need is in the FSM. You will have to do some digging but it is there. The above should get you started.
