Ford 6.7 PowerStroke Torque Specs Chart: 2011-2025 (Complete)
The 6.7 Powerstroke has gone through three distinct engineering generations since 2011, and torque specs are not identical across them. Using a 2011 head bolt spec on a 2019 truck, or torquing an intake bolt in ft-lb instead of in-lb, is how owners strip threads, crack composite parts, or blow a head gasket during reassembly.
This chart covers the 2011 to 2016 first generation, the 2017 to 2019 second generation, and the 2020 to 2025 third generation including the High Output variant. Confirm your build date or VIN before you start torquing anything on a generation boundary year.
Why 6.7 Powerstroke Torque Specs Change By Generation and Year
Ford’s first Super Duty diesel it designed entirely in-house arrived in 2011 with its own fastener set for the head, rods, mains, and fuel system. The 2017 model year brought a running change to the injector supply tube torque procedure, moving from a foot-pound final torque to an angle-torque method. The 2020 redesign carried that same angle-torque fuel system procedure forward and added the 2023 to 2025 High Output variant, which Ford recommends verifying by VIN before deep engine work since internal components differ from the standard-output engine.
Treat any generation boundary year, like a late 2016 build or an early 2020 build, as a reason to double check your exact VIN against a 6.7 Powerstroke High Output specs before assuming a torque value carries over.
How To Read This 6.7 Powerstroke Torque Chart Ft-Lb In-Lb and Nm
A few rules apply across every table below.
- 12 in-lb equals 1 ft-lb. An 89 in-lb spec is about 7.4 ft-lb, not 89 ft-lb. Torquing a small intake or sensor bolt to 89 ft-lb will snap it.
- Factory head bolts, connecting rod bolts, and injector hold-down bolts are torque-to-yield fasteners. They stretch permanently during the angle-torque steps and cannot be reused. Buy new bolts every time you remove them.
- Multi-bolt patterns like heads, intake manifolds, and wheels get tightened in a star or criss-cross pattern, not a circle, so clamping force lands evenly.
- Angle-torque steps written as plus 90 degrees or plus 65 degrees require a torque angle gauge. A wrench click at that stage tells you nothing.
- Aftermarket head studs never use the factory head bolt torque. Follow the stud manufacturer’s own procedure.

2017 to 2019 6.7 Powerstroke Torque Specs Chart
Head bolt, rod bolt, and main bearing values carry over from Gen 1. The fuel system procedure changed.Component Torque Notes Main cylinder head bolts M12 20 Nm / 177 in-lb, then 36 ft-lb x3 passes, then +90 degrees x3 New torque-to-yield bolts only Minor cylinder head bolts 30 Nm / 22 ft-lb Connecting rod bolts 45 Nm / 33 ft-lb, then +90 degrees New bolts only Main bearing vertical bolts Snug, then 20 Nm / 15 ft-lb all, then 80 Nm / 59 ft-lb outer, then 160 Nm / 118 ft-lb inner, then +90 degrees all Main bearing side bolts 40 Nm / 30 ft-lb, then +90 degrees Injector hold-down bolt 30 Nm / 22 ft-lb, then +90 degrees New bolts only Fuel rail mounting bolts 24 Nm / 18 ft-lb Injector supply tube fitting to injector 10 Nm / 89 in-lb, then +65 degrees Replaces the Gen 1 pre-tighten and final ft-lb method Injector supply tube fitting to fuel rail 10 Nm / 89 in-lb, then +65 degrees High pressure fuel line nuts 35 Nm / 26 ft-lb Pump and line kit service Oil pan drain plug 19 ft-lb for steel pan service
If your factory-style repair reference still lists the older pre-tighten plus final ft-lb fuel tube method, cross-check the build date. Ford moved to the angle-torque method for the injector supply tube starting with this generation.
2020 to 2025 High Output 6.7 Powerstroke Torque Specs Chart
The fuel system procedure from the 2017 to 2019 generation carries forward. Confirm 2023 to 2025 High Output trucks by VIN before short-block or head work, since Ford flags this generation for verification on critical internal specs.Component Torque Notes Main cylinder head bolts M12 20 Nm / 177 in-lb, then 36 ft-lb x3 passes, then +90 degrees x3 Verify 2023-2025 High Output by VIN Minor cylinder head bolts 30 Nm / 22 ft-lb Connecting rod bolts 45 Nm / 33 ft-lb, then +90 degrees Verify High Output by VIN Main bearing vertical bolts Snug, then 20 Nm / 15 ft-lb all, then 80 Nm / 59 ft-lb outer, then 160 Nm / 118 ft-lb inner, then +90 degrees all Verify High Output by VIN Main bearing side bolts 40 Nm / 30 ft-lb, then +90 degrees Injector hold-down bolt 30 Nm / 22 ft-lb, then +90 degrees New bolts only Fuel rail mounting bolts 24 Nm / 18 ft-lb Injector supply tube fitting to injector 10 Nm / 89 in-lb, then +65 degrees Some references list 60 degrees, confirm with your exact repair procedure Fuel rail supply tube fittings 10 Nm / 89 in-lb, then +65 degrees Separate fitting from the injector supply tube High pressure fuel line nuts 35 Nm / 26 ft-lb Oil pan drain plug 19 ft-lb for steel pan service

6.7 Powerstroke Intake Manifold Rear Cover and Valve Cover Torque Specs
These accessory fasteners are the same source of most stripped bolts and cracked plastic across all three generations, and they don’t change much year to year.
| Component | Torque | Notes |
|---|---|---|
| Valve cover bolts | 106 in-lb / 12 Nm | Verify by exact cover and gasket design |
| Upper intake and plenum fasteners | 89 in-lb / 10 Nm | Inch-pound spec, do not use ft-lb |
| Lower intake manifold bolts | 16 to 18 ft-lb | Verify by exact fastener location |
| MAP sensor bolt | 30 in-lb | Small fastener, easy to overtighten |
| Intercooler pipe clamps | 9 ft-lb | Confirm boot is fully seated first |
| Rear engine cover, large bolt | 35 lb-ft | Single M10x37 bolt near the starter only |
| Rear engine cover, small bolts | 7 lb-ft | Nine M6x31 bolts, do not apply the 35 lb-ft spec here |
The rear engine cover is worth a direct warning. Owner forum threads on this exact job show techs applying 35 lb-ft to all ten rear cover bolts, when that value belongs to the single large M10 bolt near the starter. The nine smaller M6 bolts snap well below 20 lb-ft. If you’re already in that area of the engine for a related job, this is a good point to also check the 6.7 Powerstroke upper oil pan guide before buttoning things back up.
For EcoBoost owners doing comparable head or timing work, the 5.4 3V cam phaser torque specs follow the same torque-to-yield and angle-torque logic covered here.
Ford F-250 and F-350 Wheel Lug Nut Torque By Year
Anyone doing engine work on a 6.7 Powerstroke is also pulling wheels for jack stand access, so this belongs in the same reference.
| Model Years | Lug Nut Torque | Notes |
|---|---|---|
| 1999 to 2004 F-250 and F-350, 8-lug | 150 to 165 lb-ft | Ford revised guidance upward during this window, 165 lb-ft is the current recommendation |
| 2005 to 2010 F-250 and F-350, 8-lug | 150 lb-ft | |
| 2008 to 2025 F-250 and F-350, 8-lug | 165 lb-ft / 224 Nm | Current M14x1.5 spec, confirmed in Ford Super Duty workshop manuals |
Retorque single rear wheel trucks at 100 miles after any wheel service. Dual rear wheel trucks get retorqued at 100 miles and again at 500 miles, and after any wheel disturbance such as a tire rotation or flat repair.
Common 6.7 Powerstroke Torque Mistakes That Break Bolts
- Reusing factory head bolts, rod bolts, or injector hold-down bolts after the angle-torque steps. These are torque-to-yield and stretch permanently the first time.
- Torquing intake, valve cover, or sensor bolts in ft-lb when the spec is listed in in-lb. An 89 in-lb bolt torqued to 89 ft-lb will snap or strip the threads.
- Applying the 35 lb-ft rear cover spec to the nine small M6 bolts instead of only the single large M10 bolt near the starter.
- Torquing aftermarket head studs to the factory head bolt spec instead of the stud manufacturer’s own procedure.
- Skipping the star or criss-cross tightening pattern on multi-bolt patterns, which causes uneven clamping and boost or coolant leaks later.
Frequently Asked Questions
What is the head bolt torque on a 6.7 Powerstroke?
Main M12 head bolts go to 20 Nm, then 36 ft-lb three times, then plus 90 degrees three times. This sequence is consistent across all three generations, 2011 through 2025.
What is the injector hold-down torque on a 6.7 Powerstroke?
All generations use 22 ft-lb, then an additional 90 degrees, with new hold-down bolts every time.
What is the lug nut torque on a Ford F-250 6.7 Powerstroke?
Current Super Duty trucks from 2008 through 2025 use 165 lb-ft on the 8-lug M14x1.5 wheel studs. Earlier trucks from 2005 to 2010 use 150 lb-ft.
Can you reuse 6.7 Powerstroke head bolts?
No. Factory head bolts are torque-to-yield and stretch permanently during the angle-torque steps. Always install new head bolts.
What happens if you over-torque a 6.7 Powerstroke intake manifold bolt?
The upper intake and plenum fasteners are an 89 in-lb spec, not ft-lb. Using a foot-pound value on these bolts can snap the fastener, strip the threads, or crack the composite intake.
