2.0L Turbo Engine Complete Assembly for 2024-2026 Jeep Wrangler

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

• Confirm the 8th digit of the VIN is 'N'.
• Verify the vehicle is a conventional gasoline model and NOT a 4xe Plug-In Hybrid (which has a charging port on the driver's fender).
• Confirm the vehicle has an 8-speed automatic transmission (850RE).

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

Special tools this job needs:

• wiTECH 2.0 Diagnostic Scan Tool
• Engine Timing Tool Kit for Jeep 2.0T
• Oil Seal Installer 9506
• High-Pressure Fuel Line Disconnect Tool
• Precision Torque Wrench
• Engine hoist and stand

Budget for these consumables at install:

• SAE 5W-30 Full Synthetic Engine Oil (meeting FCA MS-13340 or API SP / GF-6A)
• Mopar 04892339BE Oil Filter
• Mopar OAT Coolant meeting FCA MS-12106 (purple)
• NGK 90219 Laser Iridium Spark Plugs (ILZKR7G7G)
• Intake and exhaust manifold gaskets
• Turbocharger oil/coolant line O-rings and crush washers
• Front and rear main seals

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

What’s involved: Crankshaft Position (CKP) Sensor Relearn, Throttle Body Relearn, and PCM Security Re-marriage

Sources differ on PCM security re-marriage: Arm 1 states no security re-marriage is needed if reusing the original PCM (only CKP/throttle relearns), while Arm 2 states the PCM must be re-married/synchronized with the new engine's sensors due to Chrysler's locked PCM architecture. Cautiously flagged as requiring programming/re-marriage; a dealer-level scan tool (wiTECH 2.0) is required.

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

• Brittle Plastic Coolant T-Fitting (Part 68280784AB) near the turbocharger should be proactively replaced with an aftermarket billet aluminum version.
• The buried Oil-Air Separator (Mopar 4893609AD) under the intake manifold is prone to leaks and should have its seal replaced and bolts torqued while the engine is out.
• Rear main seal leaks are common; inspect and replace using specialized tool 9506 before mating to the transmission.
• Water pump inlet tube fasteners are known to back out from vibration and should be checked/re-torqued.
• Be extremely careful with the ground strap on the PCM mounting bolts to avoid difficult-to-diagnose electrical issues.

Easy to get right once you know them:

• Mixing OAT (purple) coolant with HOAT (orange/pink) or generic green coolant, which creates a clogging gel sludge.
• Stripping the aluminum oil pan drain plug by exceeding the strict 20 ft-lbs torque specification.
• Using incorrect 0W-20 oil viscosity instead of the required 5W-30.
• Reusing stretched Torque-to-Yield (TTY) fasteners on the exhaust manifold, turbocharger, or engine mounts.
• Ignoring the 8th VIN digit (N) and accidentally ordering a 4xe hybrid (ECX) or other incompatible variant.
• Underestimating the PCM lock and failing to arrange for necessary programming/relearns post-install.
