5.7L Hemi V8 Engine Complete Assembly for 2016-2017 Chrysler & Dodge - Rear

A quick look at your own vehicle makes sure the right engine shows up:

• Check your VIN's 8th digit: It must be "T" to confirm you have the 5.7L Hemi V8 engine.
• Verify your Drivetrain: Confirm your vehicle is Rear-Wheel Drive (RWD).
• Check your Transmission: Confirm your vehicle has an Automatic Transmission.
• Inspect your Oil Pan: Look under your vehicle to verify the oil pan is a standard rear-sump pan with no axle shaft pass-through tube running through it.
• Check your Engine Code: Look at your vehicle's emissions sticker or build sheet to confirm the engine code is "EZH".

What the install really takes — plan and budget with confidence:

Special tools this job needs:

• Engine hoist and heavy-duty load leveler
• Gen III Hemi-specific harmonic balancer puller/installer
• Torque angle gauge
• Fuel line disconnect tool
• Bi-directional scan tool (e.g., AlfaOBD, Appcar DiagFCA, or wiTECH)

Budget for these consumables at install:

• 7 quarts of OE-spec 5W-20 Full Synthetic Engine Oil (must meet Chrysler MS-6395 standards)
• Mopar 68191349AC oil filter
• Mopar MS-12106 (OAT - Organic Additive Technology) purple coolant
• 16 Iridium spark plugs (NGK Laser Iridium or Mopar OE, gapped to 0.043")
• Exhaust manifold gaskets
• Intake manifold gaskets
• Thermostat gasket
• Water pump gasket
• Upgraded exhaust manifold bolts/studs
• Torque-to-yield harmonic balancer bolt (Mopar part # 06506333AA or equivalent)

What your vehicle’s computers will need after the swap:

What’s involved: Crankshaft Position (CKP) Sensor Relearn (Cam/Crank Relearn)

Whenever the engine block or crankshaft position sensor is replaced, a Cam/Crank Relearn must be performed using a bi-directional scan tool. Without this calibration, the PCM cannot accurately detect misfires, which will trigger a flashing Check Engine Light, extended cranking, or a no-start condition. The PCM itself does not need to be replaced or reprogrammed unless you are changing the PCM itself.

Pro tips for a smooth first start-up — hand them to whoever does the install:

• MDS Oil Requirements: You must use exactly 5W-20 weight oil. Thicker oil will cause MDS solenoid codes and lifter failure.
• Harmonic Balancer Bolt: The crank bolt is a torque-to-yield (TTY) bolt and must be replaced. Torque spec is 129 ft-lbs, then loosen 1 full turn, then torque to 37 ft-lbs, then turn an additional 90 degrees.
• Dual Spark Plugs: There are 16 spark plugs and 8 coil packs. Change all 16 while the engine is out of the car, as reaching the rear plugs near the firewall once installed is notoriously difficult.
• Ground Straps: Ensure the main ground strap on the back of the passenger-side cylinder head to the firewall is clean and securely fastened.
• Active Exhaust Valves: If equipped, ensure the actuators are plugged back in to avoid a permanent soft code.
• Extract Broken Exhaust Bolts on the Stand: Check the donor engine's exhaust manifold bolts before dropping it into the engine bay and extract any snapped bolts while the engine is easily accessible.
• MDS Solenoid Fragility: Be extremely careful not to bump or crack the plastic solenoid housings under the intake manifold when swapping your intake over.
• Crankshaft Position Sensor Swap: To potentially avoid a trip to the dealer for a CKP relearn, swap your original, known-good Crankshaft Position Sensor from your blown engine onto the replacement engine before installation.

Easy to get right once you know them:

• Ordering for an AWD Vehicle: The RWD engine has a different oil pan and does not have the clearance/pass-through for the front axle shaft.
• Ordering for a Manual Transmission (EZC): Manual transmission Challengers do not have MDS, and the physical crankshaft pocket is different (manuals require a pilot bearing, automatics do not).
• Reusing the Harmonic Balancer Bolt: Reusing the old TTY balancer bolt causes it to lose clamping force, back out, and wobble, ruining the crank keyway.
• Using the Wrong Oil Viscosity: Putting thicker oil in a Hemi to quiet down a tick disables the MDS system, throws a P1521 code, and starves the lifters.
• Mixing Coolants: Mixing green or orange HOAT coolant with the required purple OAT coolant causes the fluid to gel, clogging the heater core and radiator.
• Reusing Old Exhaust Manifold Bolts: Reusing old bolts guarantees they will snap due to thermal cycling.
• Ignoring the "Hemi Tick" valvetrain inspection before installing.
