Dodge 5.7 HEMI Intake Manifold Torque Specs

How to use this specification correctly

1. 01

   Identify the engine code, model year, casting, gasket and exact fastener kit before disassembly.

2. 02

   Clean and inspect threads, bolt holes and mating faces using the component manufacturer's limits.

3. 03

   Follow the exact staged pattern with the specified lubricant or sealant; record torque and angle completion.

The covered 2011 Ram 5.7L procedure

Mopar's installation procedure finishes the intake-manifold bolts at 12 N·m (9 lb-ft) in its illustrated sequence. That low value is intentional for the composite manifold and molded seals; interpreting it as 9 N·m or converting it into an improvised inch-pound target changes the specification.

The procedure distinguishes a reused original manifold from a new replacement. Apply Mopar Lock & Seal Adhesive to the intake bolts with the original manifold; the factory text says the adhesive is not required when installing a new manifold.

Positioning the manifold without trapping components

Fit new intake-manifold seals and the specified PCV seals. As the assembly is lowered, connect and route the MAP sensor and short-runner-valve wiring correctly, then verify injector connectors, vacuum hoses and harness branches are clear of every sealing rail.

Start all bolts by hand and make controlled preliminary passes through the factory order before the final 9-lb-ft pass. Do not use extra torque to pull a high corner down; remove the manifold and find the displaced seal or trapped component.

Application limits across HEMI generations

This page is anchored to a 2011 Ram 2500 5.7L. Car and SUV applications, later active-runner systems and replacement aluminum manifolds may change the hardware, chemical treatment or sequence even though the engine badge remains 5.7 HEMI.

A persistent lean code or vacuum leak after installation calls for routing inspection and a controlled smoke test. Overtightening risks cracked bosses, distorted sealing rails and pulled threads without repairing the original leak path.

Why 2011 Ram 2500 5.7L HEMI V8 identification changes the specification

This value and installation workflow are anchored to the 2011 Ram 2500 5.7L factory procedure. Passenger-car HEMIs, other model years, active-runner revisions and aftermarket manifolds require application-specific confirmation.

Install new manifold and PCV seals, connect the MAP sensor and short-runner-valve wiring as the manifold is positioned, and verify that no harness, hose or vacuum connection is trapped before tightening. The procedure calls for Mopar Lock & Seal Adhesive on the bolts when reinstalling the original manifold, but says it is not required with a new manifold.

Assembly controls that prevent false torque

• Use the specified thread condition and lubricant.
• Separate main bolts from small or special-position fasteners.
• Use an angle gauge where torque-to-yield stages are specified.
• Stop if a fastener reaches the setting before the joint seats normally.
