Dodge 5.7 HEMI Intake Manifold Torque Sequence
5.7 HEMI intake sequence for documented 2003-17 applications: factory ten-bolt 12 N-m pattern, seal and thread-treatment notes, plus aftermarket limits.
For the factory intake on the cited 2011-2017 Dodge Challenger/Charger and Chrysler 300 5.7L HEMI, inspect the intake seals, position the manifold and tighten all ten bolts in Mopar's numerical sequence to 12 N-m (9 lb-ft). With the throttle-body/front end at the right in Mopar's top-view figure, the upper row is 9-5-1-4-8 and the lower row is 10-6-2-3-7. If reinstalling the original manifold, Mopar specifies Lock & Seal Adhesive on the intake bolts; it says that treatment is not required with a new manifold. Earlier 2003-2008 service information also lists 12 N-m (105 in-lb) with a center-out crisscross order, but connections and physical illustrations must be verified for the exact vehicle.
The 5.7 HEMI name spans trucks, SUVs and rear-wheel-drive cars built across several generations. The intake manifold changed from early non-VVT applications to later Eagle/VVT engines with different accessory, MAP, PCV and short-runner-valve arrangements. Fortunately, the cited factory procedures agree on a light 12 N-m clamp for the production manifold, but that agreement does not make every removal step or aftermarket intake interchangeable.
Mopar's 2011-2017 Stage 2 guide includes a complete factory service extract for Charger, Challenger and 300 applications. Its installation page shows ten physical positions, begins near the center and alternates outward. It also makes two often-missed distinctions: seals may be reused only if they have no cuts, tears or deformation, and Lock & Seal is specified when reinstalling the original manifold but not when installing a new one.
A safe guide must also show where the factory procedure ends. Holley's current fabricated Gen III HEMI manifold uses only eight supplied mounting bolts and a 10.3 lb-ft final value. Using its number on a stock composite manifold—or forcing the Mopar ten-position drawing onto an eight-hole casting—creates a procedure that neither manufacturer published.

This page separates the ten-bolt factory composite manifold from eight-bolt fabricated aftermarket systems. Holley's cited Sniper Gen III HEMI manifold uses eight supplied Allen bolts and 10.3 lb-ft (124 in-lb), so its hardware and diagram cannot be mixed with Mopar's ten-bolt sequence. Model year, vehicle platform, active-runner equipment and manifold part number must select the branch.
How to use this specification correctly
- 01
Identify the vehicle, model year, engine and installed intake by part number. Confirm a factory-style ten-bolt 5.7L manifold and note whether it has active/short-runner control, a manifold-mounted EVAP solenoid or other generation-specific equipment.
- 02
Relieve fuel pressure by the vehicle procedure, disconnect the negative battery cable and keep sparks and flame away. Label injector connectors, MAP, electronic throttle control, active-runner connector, EVAP, PCV and brake-booster hoses before disturbing them.
- 03
Disconnect the fuel quick-connect with the correct release tool and cover the line. Remove harness retainers and rear connections that can be damaged when the manifold is lifted; do not pull on wires or plastic vacuum nipples.
- 04
Loosen the ten bolts from the outside toward the center in a progressive crisscross pattern. Lift the manifold evenly and cover every head port immediately so dirt, fasteners and cleaning liquid cannot enter a cylinder.
- 05
Clean the head sealing tracks with a method safe for aluminum and composite parts. Inspect the manifold for cracks around bolt bosses, warped sealing rails, loose fittings and damage to active-runner hardware; a cracked composite shell is replaced, not repaired with extra torque.
- 06
Inspect all intake and PCV seals. Mopar permits reuse in the cited procedure only when there are no cuts, tears or deformation. Replace any hardened, flattened, swollen or displaced seal and keep the molded sealing lips clean and correctly seated.
- 07
Choose the documented thread treatment. When reinstalling the cited original manifold, apply Mopar Lock & Seal Adhesive to the intake bolts; Mopar says it is not required when installing a new manifold. Do not substitute anti-seize or oil without the exact component instruction.
- 08
Lower the manifold squarely without rolling a seal. Connect rear MAP, short-runner or brake-booster fittings when access requires it, align all ten holes and hand-start every bolt. Stop if a fastener binds or bottoms before its flange contacts.
- 09
Orient the Mopar diagram with the throttle body/front at the right. Tighten positions 1 through 10 progressively and finish all ten at 12 N-m (9 lb-ft). Use a low-range calibrated wrench; the light composite joint is easy to damage with a large foot-pound tool.
- 10
Reconnect fuel, EVAP, PCV, MAP, injector and throttle circuits, then cycle the fuel pump and inspect before cranking. Start the engine, check fuel and vacuum leaks, command/test the active-runner system where fitted and review fuel trims and misfire data after warm-up.
Reading the Mopar ten-bolt diagram
Mopar's top view places the throttle body and engine front at the right. The upper physical row reads 9, 5, 1, 4, 8 from rear to front; the lower row reads 10, 6, 2, 3, 7. Tightening proceeds numerically from 1 through 10, beginning at the center pair and crossing between head rails as the pattern expands outward.
Do not mirror the picture because you are standing at the radiator or firewall. Identify the throttle body in the actual engine bay, match it to the right side of the diagram and mark each bolt after it is completed. If access forces a tool change, record the last finished position before resuming.
Early and Eagle/VVT 5.7L applications
The cited 2005 Ram manual uses the same 12 N-m value and directs a middle-to-outside crisscross pattern, but its removal procedure and sensor/air-fuel-management hardware differ from the 2011-2017 car figure. The later Eagle/VVT family can add short-runner-valve controls and different rear connections.
Use the physical Mopar map here only after the installed ten-bolt layout and front orientation match. For a 2003-2008 truck or a swapped early engine, keep the year/platform service illustration beside the engine rather than assuming every connector or fastener location carried forward unchanged.
Lock & Seal applies to a specific reuse condition
Mopar says to apply its Lock & Seal Adhesive to the intake-manifold bolts when reinstalling the original manifold and notes that it is not required with a new manifold. That instruction is part of the documented friction and retention condition for the 12 N-m value.
Clean old compound only by the approved method and do not flood the holes. Threadlocker, oil and anti-seize alter friction differently. An aftermarket kit that supplies its own coated bolts or lubricant supersedes the factory treatment for that kit.
Factory composite versus fabricated aluminum
The stock manifold uses ten bolts. Holley's cited fabricated Gen III HEMI intake uses eight supplied Allen-head bolts and 10.3 lb-ft. Its O-ring grooves, casting stiffness and fastener arrangement are a separate engineered joint even though it fits 5.7L heads.
Count holes before selecting a diagram. If eight fasteners are present, stop using the Mopar 1-through-10 map and open the aftermarket manual. The throttle-body torque, fuel-rail bracket values and MAP/EVAP adaptations are also separate from the head-to-manifold fasteners.
Leak symptoms after intake service
- Fuel smell or wetness at an injector requires immediate shutdown and pressure release.
- A high or unstable idle can come from a rolled port seal, disconnected booster/PCV/EVAP hose or throttle-body seal.
- Positive fuel trim on one bank points toward a bank-specific port or injector leak; both banks suggest a shared vacuum source.
- Active-runner or MAP faults after service often indicate a missed rear connector or pinched harness.
- A cracked bolt boss or distorted composite flange should be replaced, not corrected with more torque.
- Smoke testing and scan data are safer diagnostics than repeatedly tightening a warm plastic manifold.

What is the 5.7 HEMI intake bolt sequence?+
In Mopar's top view with the throttle body/front at right, the upper row is 9-5-1-4-8 and the lower row is 10-6-2-3-7. Tighten numerically 1 through 10.
How many bolts hold the factory 5.7 HEMI intake?+
The factory-style manifold shown here uses ten mounting bolts, five along each cylinder-head rail.
Should 5.7 HEMI intake bolts use threadlocker?+
For the cited later Mopar procedure, use Mopar Lock & Seal when reinstalling the original manifold; Mopar says it is not required with a new manifold. Verify the exact year and parts.
Can 5.7 HEMI intake seals be reused?+
Mopar allows reuse in the cited procedure only when the seals have no cuts, tears or deformation. Replace questionable seals rather than compensating with torque.
Does the factory sequence apply to a Holley fabricated intake?+
No. Holley's cited fabricated intake uses eight supplied bolts and a separate 10.3 lb-ft sequence. Use its figure and hardware instructions.
Does this page cover a 2020 Ram 1500 eTorque?+
Not automatically. Later DT/eTorque applications can have revised manifold, bolts and packaging; obtain the VIN-specific Stellantis procedure before service.
What should be checked after installing the manifold?+
Pressure-check the fuel system, verify every MAP/SRV/EVAP/PCV connection, then inspect idle, fuel trims, misfire counters and active-runner operation after startup.
