Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Manifold, Intake: Installation
The intake manifold seals (1, 3) may be used again, provided no cuts, tears, or deformation have occurred.
- Inspect the intake manifold seals and replace as necessary.
- Install the intake manifold seals (1, 3).
- Position the intake manifold (2) in place.NOTE:
If reinstalling the original manifold apply Mopar® Lock & Seal Adhesive to the intake manifold bolts. Not required when installing a new manifold.
- Apply Mopar® Lock & Seal Adhesive to the intake manifold bolts.
- Using the sequence shown in the illustration, install the intake manifold bolts and tighten to 12 N.m (9 ft. lbs.).NOTE:
The factory fuel injection electrical harness is numerically tagged (INJ 1, INJ 2, etc.) for injector position identification. If the harness is not tagged, use the noted electrical connector's location during removal.
- Connect the fuel injector electrical connectors (8).
- Position the electrical harness (7) as shown in the illustration.
- Connect the electrical connector (6) at the throttle body.
- Connect the EVAP vacuum purge hose (5).
- Connect the make up air hose (4) at the intake manifold.
- Connect the fuel supply line (3) at the fuel rail.
- Connect the brake booster vacuum hose (2) at the rear of the intake manifold.
- Connect the MAP sensor (1) electrical connector at the rear of the intake manifold.
- Position the resonator onto the throttle body and air cleaner housing.
- Tighten the hose clamp at the throttle body (4) to 5 N.m (45 in. lbs.).
- Install the resonator retaining bolt (3) and tighten to 5 N.m (45 in. lbs.).
- Tighten the hose clamp at the air cleaner housing (2) to 5 N.m (45 in. lbs.).
- Connect the electrical connector at the Intake Air Temperature (IAT) sensor (1).
- Install the engine cover (2).
- Install the oil fill cap (1).
- Connect the negative battery cable (2).
- Start the engine and check for leaks.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
