2006 Dodge Ram 5.7 HEMI Exhaust Manifold Torque
2006 Dodge Ram 5.7 HEMI Exhaust Manifold Torque with fastener-group distinctions, installation cautions, application limits and official source lookup.
For the covered 2006 Ram 2500 5.7L HEMI, tighten the exhaust-manifold bolts in the factory sequence to 18 lb-ft (25 N·m). Tighten the heat-shield nuts separately to 11 lb-ft (15 N·m).
For the covered 2006 Ram 2500 5.7L HEMI, tighten the exhaust-manifold bolts in the factory sequence to 18 lb-ft (25 N·m). Tighten the heat-shield nuts separately to 11 lb-ft (15 N·m).
The values apply to the documented 2006 Ram 2500 factory manifolds and hardware. Other HEMI years, car applications, revised bolts and shields, aftermarket headers and repaired cylinder-head threads require their exact instructions.
Install a new gasket and follow the illustrated sequence rather than merely sweeping left to right. Mopar's procedure limits gasket-surface distortion to 0.008 inch per foot; check flatness and cracks and repair broken rear bolts instead of increasing torque on the remaining fasteners.

Dodge 5.7 Hemi Exhaust Manifold Torque Spec
| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| Manifold bolts | 18 lb-ft | 25 N·m; illustrated sequence |
| Heat-shield nuts | 11 lb-ft | 15 N·m; separate hardware |
| Maximum flange variation | 0.008 in per ft | 0.2 mm per 300 mm |
| Exhaust-pipe flange | Separate specification | Do not reuse manifold-bolt value |
Install a new gasket and follow the illustrated sequence rather than merely sweeping left to right. Mopar's procedure limits gasket-surface distortion to 0.008 inch per foot; check flatness and cracks and repair broken rear bolts instead of increasing torque on the remaining fasteners.
How to use this specification correctly
- 01
Identify the exact engine, component, fastener size and hardware instructions.
- 02
Clean and inspect threads and mating faces; apply only the specified lubricant or sealant.
- 03
Tighten in gradual balanced passes and verify any angle, cure-time or recheck instruction.
Use the illustrated 18-lb-ft sequence
Install every manifold bolt loosely with a new gasket, then follow Mopar's numbered sequence to 18 lb-ft. The heat shield is a separate layer whose nuts use 11 lb-ft; labeling hardware prevents the shield setting from being confused with the manifold joint.
The exhaust-pipe flange and engine-mount hardware disturbed for access have their own specifications. A complete repair worksheet should keep each nearby joint on a separate row.
Broken bolts and flange flatness
Mopar limits gasket-surface variation to 0.008 inch per foot. Check the removed manifold with a straightedge and inspect for cracks; clamping a warped flange harder can break another bolt without closing the leak uniformly.
Extract broken rear bolts without damaging the aluminum head, restore questionable threads correctly and use the exact revised hardware when a model-specific kit applies. Headers and later HEMI revisions do not inherit this 2006 truck chart automatically.

Dodge 2006 Ram 2500 5.7L HEMI specifications can change by model year, engine, platform, wheel, and installed component. Confirm the VIN or engine identity, part numbers, fastener condition, and the current manufacturer instructions before service.
2006 Dodge Ram 5.7 HEMI Exhaust Manifold Torque FAQs
What is the 2006 Dodge Ram 5.7 HEMI exhaust-manifold torque?+
Tighten the factory manifold bolts in the illustrated sequence to 18 lb-ft (25 N·m).
What is the heat-shield nut torque?+
The covered heat-shield nuts use 11 lb-ft (15 N·m), separate from the manifold bolts.
How flat must the HEMI manifold flange be?+
The cited procedure limits variation to 0.008 inch per foot (0.2 mm per 300 mm).
Can extra torque compensate for a broken rear bolt?+
No. Remove the broken fastener, inspect the threads and flange, and restore the complete joint.
