The proper torque for the 3.5 is 14 to 22 ft-lbs. Right out of the Nissan manual. The ignition coil bolt is 57 to 66 INCH-lbs.altgoat said:Anyone know what the torque spec is for spark plugs on the 3.5 (2002 Altima)?
Adam, Where in the FSM is that ignition coil bolt torque specified? I cannot find it anywhere. Thanks!The proper torque for the 3.5 is 14 to 22 ft-lbs. Right out of the Nissan manual. The ignition coil bolt is 57 to 66 INCH-lbs.
The proper torque for the 2.5 is 15 to 21 ft-lbs. Right out of the Nissan manual. The ignition coil bolt is 46 to 64 INCH-lbs.
Be sure to torque the plugs correctly...stripping the threads there is not fun!!!!
Hey Doug,20 ft-lbs is about right, and a lot lower than most disciples of the Teitenhoff Institute would think. Trust me...I stripped an old Mazda aluminum head back in the day without even really trying.
Much obliged for the talk-on, Doug!Eddie....love the request for 'teach a guy to fish'! Ok, expand my sig, click on the Altima FSM's, click on 2002, then on em.pdf (engine mechanical). you'll find this diagram

I assumed you had the four banger, doubt the VQ is much different though. One thing to watch are the units. The coil bolt is ~50 in-lb, or only about 4 ft-lbs of torque. The plug...about 20 ft-lbs.
in general, aim for the middle of the range, so for the plug which is 15-21...aim for 18 on your torque wrench.
