3.6L Engine Complete Assembly for 2016-2022 Jeep Grand Cherokee
Product Notes Read before buying
For 2021-2022 Jeep Grand Cherokee, this engine fits the 'WK' body style only (the continuation of the fourth generation), not the redesigned 'WL' body style. Please verify your vehicle's 8th VIN digit is 'G'. This is a complete engine assembly, but some external components (such as the oil pan, intake/exhaust manifolds, and accessories) may need to be transferred from your original engine to ensure proper fitment.
Voice or type your vehicle details and Wrenchy will confirm fitment in seconds.

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 'G'.
- Verify the 6th digit of the VIN is 'F' or 'E' (confirming WK-body Grand Cherokee).
- Confirm drivetrain (AWD vs 2WD) to ensure correct transfer of oil pan and brackets.
- Inspect valve covers for the presence of VVL solenoid electrical connectors on the front face.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Camshaft Phaser Locking Tool Kit (CTA Tools 1205 or Miller 10200A / 10202)
- Torque Angle Gauge
- Engine hoist and stand
- Torque wrenches (inch-pounds and foot-pounds)
Budget for these consumables at install:
- Engine Oil: 0W-20 or 5W-20 full synthetic oil meeting Chrysler MS-6395 specifications (6-quart capacity for Grand Cherokee PUG)
- Oil Filter: OEM Mopar filter (Part # 68191349AC or equivalent)
- Coolant: Mopar OAT (Organic Additive Technology) 50/50 Pre-Mixed Coolant meeting MS.90032 / MS-12106
- Upper and lower intake manifold plenum gaskets
- Exhaust manifold gaskets
- Thermostat housing and water pump gaskets
- Spark Plugs (6 new, OEM Champion or NGK Laser Iridium, gapped to 0.043")
- Torque-to-Yield (TTY) fasteners (e.g., harmonic balancer bolt, head bolts if disassembled)
- Rear main seal and front crankshaft seal
What your vehicle’s computers will need after the swap:
What’s involved: Crankshaft Position (CKP) Sensor Relearn and Camshaft Position Sensor Relearn
sources differ: Arm 1 states a dealer scan tool is required; Arm 2 states it is highly recommended but some high-end aftermarket tools may perform it. A professional bi-directional scan tool (such as FCA's wiTECH, Autel, or Snap-on) is required to initiate the relearn procedures.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- The AWD Front Differential Squeeze: AWD models require maneuvering the lower oil pan past the steering rack and front differential. Unbolt engine mounts and rotate the engine slightly to clear.
- Fragile VVL Solenoids and EGR Tubes: Plastic connectors and aluminum lines on the front of valve covers and cylinder heads are highly fragile. Do not bump them with hoist chains.
- Oil Filter Housing Torque Spec: Torque mounting bolts strictly to 106 in-lbs (12 Nm) in sequence. Over-tightening will crack the plastic housing.
- Torque Converter Alignment: Ensure torque converter is fully seated in the transmission pump before mating the engine to avoid destroying the pump.
- Ground Straps: Ensure all engine and transmission ground straps are clean, secure, and correctly re-installed.
Easy to get right once you know them:
- Reusing a brittle plastic oil cooler housing instead of upgrading to an all-aluminum aftermarket unit.
- Attempting to swap accessories, valve covers, or sensors from a 2011-2015 'Classic' 3.6L engine onto this 2016+ 'Upgrade' engine.
- Crankcase overfilling due to checking the dipstick immediately after pouring oil (must wait 5 to 10 minutes for slow drain-back).
- Neglecting a thorough coolant flush if the original engine suffered a failure that mixed oil into the coolant.
- Mixing coolant types or using generic 'all-makes' coolant instead of specified Mopar OAT coolant.
- Skipping the Crankshaft Position (CKP) sensor relearn procedure.
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: Ensure recall has been addressed or transfer original, undamaged fuel rail to donor engine.
🔎 Recommended at install: Manufacturing issue causing premature wear on VVL system; check for rough idling, valvetrain noise, and DTCs.
🔎 Recommended at install: Install brand-new, high-quality spark plugs during the swap to prevent misfires.
🔎 Recommended at install: Wait 5 to 10 minutes after filling before checking dipstick to avoid overfilling.
🔎 Recommended at install: Replace failed roller rocker arms before they score and round off the camshaft lobes.
🔎 Recommended at install: Replace plastic housing with an upgraded all-aluminum aftermarket unit (e.g., Dorman) during the swap.
🔎 Recommended at install: Perform PCM software update at the dealer to prevent aggressive EGR operation.
🔎 Recommended at install: Perform PCM software update to prevent cruise control cancellation failure.

- 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

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

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.
