Product Notes Read before buying
This is a used engine assembly for vehicles with a 3.0L V6 EcoDiesel engine (8th VIN digit 'M') and an automatic transmission. This engine is sold as a long block and does not include the turbocharger. To complete the installation, you will need to transfer the turbocharger, induction system, electrical components, and exhaust manifolds from your original engine.

Know This Engine Before You Buy
The research behind our purchase interview — recalls, bulletins and real install economics for this engine family:
A quick look at your own vehicle makes sure the right engine shows up:
- Verify the 8th digit of the VIN is 'M'.
- Inspect coolant reservoir for oil contamination (milky, sludgy substance).
- Confirm drivetrain layout (4WD/AWD vs RWD).
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- VM Motori 3.0L Timing Tool Kit (VM.10338, VM.10339, VM.10389, VM.10226)
- Fuel System Priming / Scan Tool
- Injector Puller Tool
- Engine hoist
- Torque wrenches
Budget for these consumables at install:
- 5W-40 Full Synthetic Engine Oil (meeting FCA MS-10902 or MS-12991, 8.1 quarts)
- New premium cartridge-type oil filter
- Mopar OAT (Organic Additive Technology) 10-Year/150,000 Mile Purple Coolant
- New fuel filter
- Intake manifold gaskets
- Exhaust manifold gaskets
- Oil cooler seals
- Fuel injector copper crush washers and O-rings
- Rear main seal
- New serpentine belt and tensioner
What your vehicle’s computers will need after the swap:
What’s involved: Fuel Injector IMA Coding (Flow Adjustment), Crankshaft Position Sensor Relearn, and PCM Reprogramming
If using injectors with this replacement engine, program their 7-character IMA codes into the PCM. If transferring original injectors, return them to their exact original cylinders. A crankshaft position sensor relearn and PCM software flash are also required.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- The 30-Minute Oil Fill Rule: Wait at least 30 minutes after pouring fresh oil before starting the engine to prevent bearing starvation.
- CP4 High-Pressure Pump Timing: The gear-driven pump must be timed to the engine during installation.
- Oil Cooler Debris Contamination: Prevent dirt from falling into open oil ports during transfer to avoid immediate bearing failure.
- Vacuum Coolant Filling: Use a vacuum coolant refilling tool to prevent trapped air pockets.
- Turbocharger Transfer: Ensure all oil and coolant lines are clean and free of debris when transferring the turbo.
- EGR and Intake Cleaning: Thoroughly clean carbon buildup from the intake manifold and EGR passages before installation.
- Torque-to-Yield (TTY) Bolts: Replace critical TTY fasteners (like injector hold-down bolts) with brand-new ones.
Easy to get right once you know them:
- Dry-Starting the Fuel System without priming, which destroys the Bosch CP4.2 pump.
- Reusing Injector Hold-Down Bolts, leading to injector blow-by.
- Mixing Coolant Types (OAT with HOAT or generic green), which turns the coolant into a thick gel.
- Using Outdated Oil Specs (5W-30 instead of the updated 5W-40 full synthetic).
- Ignoring Fuel System Contamination after an HPFP failure, which destroys the new engine's fuel system.
- Not Verifying Recall Status on the vehicle before installation.
- Improper ECU/PCM Handling by assuming the engine is plug-and-play.
Not issues with the units on this page — the manufacturer documented these for every engine of this family, wherever you buy one. Handy for your installer:
🔎 Recommended at install: Replace the HPFP and potentially other contaminated fuel system components.
🔎 Recommended at install: Replace the EGR cooler, and inspect and replace the intake manifold if necessary.
🔎 Recommended at install: Software update to use camshaft signal as backup, or replace the tone wheel itself.
🔎 Recommended at install: Ensure timing gear is secure; timing sprocket can slip causing engine failure.
🔎 Recommended at install: FCA retroactively issued TSB 18-078-16 to change the oil specification to a heavier 5W-40 full synthetic.
🔎 Recommended at install: Replace oil cooler and flush cooling system to prevent oil and coolant mixing.

Policies, in plain English.
Shipping & Handling
- Ships by LTL freight on a pallet — a real freight truck, not a parcel van
- Your checkout freight quote covers delivery to your door (liftgate service included for residential addresses)
- The carrier calls ahead to schedule a delivery window — someone must be present to receive it
- Typically palletized and picked up within 2–3 business days; transit time depends on distance
120-Day Warranty
This part includes a 120-day warranty.
- If the part fails within the warranty window, we'll replace it or refund per the coverage terms
- Coverage is parts-only — installation labor is not included
- Warranty covers defects — not installation errors, misuse, or damage after installation
Your pre-purchase interview reviews these exact terms with you before anything is charged.
Returns (30 Days)
We accept returns of uninstalled parts within 30 days of delivery for this part.
- Defective parts: We will replace the part or issue a refund at our discretion
- Programming: "Needs to be programmed to my vehicle" is not a valid return reason. Many modules require dealer programming — we're happy to help connect you with resources if your dealer says it's not programmable
- Return shipping: This part ships by freight (LTL) — the part price is refundable per the terms above, but shipping costs are non-refundable and return freight follows the seller's return terms. Your pre-purchase interview walks through the exact numbers before you buy
- Parts must be returned in original packaging and unmodified condition
- Poorly packaged returns that arrive damaged will not be credited
Damaged in Shipping?
Freight damage is rare — and you're fully protected when you do two things at delivery:
- Inspect before you sign — you're allowed time to look the pallet over while the driver waits
- Write any damage on the delivery receipt before signing — that one line is what makes a freight claim succeed
- Severe damage? Refuse the delivery — it goes back at no cost to you and we make it right
- Photograph the pallet before unwrapping; report concealed damage within 24 hours of delivery
We handle the carrier claim — you just help document it. Your pre-purchase interview walks through this checklist too.
Order Cancellation
Cancel before shipment for a full refund. Once the pallet has been built, a preparation charge may apply — and once the freight carrier picks it up, shipping costs are non-refundable and standard return terms apply. Your pre-purchase interview shows the exact numbers before you pay.
