2012-2014 Dodge Dart Fiat 500 1.4L Remanufactured Engine

Description

Halt MultiAir actuator pumping loss, eliminate crankcase oil consumption under continuous urban transit, and maintain 50 PSI hot cruise oil pressure across demanding courier routes using the Dodge Dart 1.4L MultiAir Remanufactured Engine engineered for 2012 to 2014 Dodge Dart and Fiat 500 commercial fleet vehicles. This 16-valve electro-hydraulic MultiAir platform restores high fuel economy and responsive city operation.

Cast from high-density gray cast iron with siamesed cylinder bores, this FIRE-series engine block halts bore distortion under continuous thermal cycling. A precision-ground nodular iron crankshaft turns within tri-metal bearings, linked to forged steel connecting rods and graphite-coated hypereutectic aluminum pistons. Cylinder bores receive diamond plateau honing with Ra 30 deck micro-finishes for MLS gasket sealing. Dry mass measures 245 lbs with a 4.0-quart capacity stamped steel oil pan.

Key Features of Dodge Dart 1.4L MultiAir

Metropolitan fleet operators buy Dodge Dart 1.4L MultiAir remanufactured engine packages to lower vehicle maintenance expenses and keep urban couriers on schedule. Each rebuilt long block undergoes automated cold-test spin verification to confirm proper oil gallery pressurization before distribution.

• MultiAir electro-hydraulic variable valve actuation phasers continuously regulate intake valve lift and timing
• Single overhead camshaft actuates exhaust valves directly and drives intake hydraulic pumping elements
• 0.0010 to 0.0017 inch main bearing clearances maintain solid hydrodynamic lubrication film strength
• Multi-layer steel cylinder head gaskets maintain combustion seals across extreme summer city heat
• High-flow internal trochoid oil pumps channel pressurized lubricant to MultiAir actuator bricks
• Induction-hardened valve seats prevent valve face recession during continuous city stop-and-go driving
• Precision rotating package balancing protects Dodge Dart 1.4L MultiAir driveline parts from vibration

Dart MultiAir Operational Combustion Limits

Operating lubricant pressure produces 18 to 22 PSI during warm idle and expands to 50 through 65 PSI at 2800 RPM cruise speeds. Internal coolant temperatures stabilize between 190°F and 205°F through regulated cross-flow cooling circulation. This 1.4-liter MultiAir engine outputs 160 horsepower at 5500 RPM and 184 lb-ft continuous torque at 2500 RPM with a 9.8:1 compression ratio. Cylinder cranking pressure measures between 170 and 185 PSI across all four chambers. The cooling system rejects 2200 BTU per minute during loaded highway transit.

Dart Crankshaft Transaxle Alignment Thresholds

A 6-bolt rear crankshaft flange mounts flush to factory dual-clutch transmission flexplates or manual flywheels. Measured crankshaft thrust endplay checks out between 0.0030 and 0.0070 inches. The 0.984-inch front crankshaft snout features a single keyway to position the timing belt drive gear and harmonic balancer, holding true accessory drive belt pulley alignment.

Dart Fleet Lubricant Servicing Protocols

Technicians must prime the engine oil pump and MultiAir actuator brick prior to first startup by cranking the starter without ignition until oil pressure warning lamps extinguish. Fill the crankcase with 5W-40 synthetic motor oil meeting Chrysler MS-12991 standards. This production engine is not engineered for turbo upgrades exceeding factory boost, nitrous injection, or competitive drag racing.

• Check crankcase oil level and coolant tank fluid volume each shift before driving
• Drain break-in motor oil and install fresh oil filter after 500 initial miles
• Perform routine oil and filter changes every 4000 miles during commercial transit cycles

Dart Commercial Warranty Freight Details

Commercial fleet purchasers receive a 3-Year / 100,000-Mile commercial fleet warranty covering structural casting and internal moving components. The heavy-duty wood crate contains one remanufactured long block engine, a complete engine install gasket set, spark plug well seals, front timing cover seals, dyno test documentation, and priming instructions.
