'99 & up 7.3L Power Stroke Engine and DrivetrainDiscussion of the 99 & up 7.3L Power Stroke diesel engine and drivetrain in the 1999-Up Super Duty trucks and Excursions. No gas engine discussion allowed except on transmissions and drivetrain that pertain to all models. Please confine discussion of topics in this forum to those items that are specific to the 7.3L Power Stroke engine.
The service manual says 14 lb-ft for glow plugs and doesn't mention using anti-sieze. There's a tapered seat at the bottom of the threads that makes the seal, so the threads will be bathed in oil from above. Anti-sieze probably not necessary.
I was looking up the torque specs for my new injectors in the service manual and checked the glow plug specs while I had it open. It reads 124 in/lbs or 14 Nm. Might want to double check before you torque it down.
I come up with 19 Nm or 14 LB/FT for the glow plugs.

Checked again says 14Nm. I would be inclined to believe you however. It is a Ford shop update manual but it was printed for the 99 model. Don't know if there were any updates made or if this thing is wrong. Guess you can't believe everything you read. What should the injector hold down clamp mounting bolt be torqued to? This thing says 120 inch/lbs [img]/ubbthreads/images/graemlins/shrug.gif[/img]
