2004 Chrysler Pacifica 3.5L Remanufactured Engine

Description

Propel regional executive transport wagons and municipal administrative crossover fleets across continuous highway transit routes under 170 PSI cylinder compression force without detonation through the Chrysler Pacifica 3.5L Remanufactured Engine engineered for 2004 Chrysler Pacifica commercial crossover platforms. This 24-valve SOHC V6 powertrain restores responsive passing torque, quiet valvetrain operation, and dependable multi-shift service.

Constructed with a deep-skirt high-strength cast iron block, this rigid 60-degree V6 utilizes cross-bolted main bearing caps that suppress bottom-end deflection during high-speed highway travel. A micro-polished forged steel crankshaft turns within tri-metal bearings, linked to forged steel connecting rods and graphite-coated hypereutectic pistons. Cylinder bores receive diamond plateau honing with Ra 30 deck micro-finishes for aluminum cylinder head clamp retention. Dry weight registers at 390 lbs with a 5.5-quart capacity oil pan.

Key Features of Chrysler Pacifica 3.5L

Administrative fleet directors buy Chrysler Pacifica 3.5L remanufactured engine packages to keep municipal executive wagons running on schedule. Every remanufactured long block undergoes vacuum decay testing to guarantee total fluid circuit separation before crate departure.

• Single overhead camshafts regulate four valves per cylinder through low-friction roller rocker followers
• 0.0011 to 0.0019 inch main bearing clearances maintain solid hydrodynamic lubrication film strength
• Variable manifold intake runner valves broaden torque across low and high RPM ranges
• Multi-layer steel cylinder head gaskets maintain combustion seals across extreme summer transit heat
• High-flow internal trochoid oil pumps channel pressurized lubricant to overhead camshaft journals
• Induction-hardened valve seats prevent valve face recession during sustained highway cruise operations
• Precision rotating package balancing protects Chrysler Pacifica 3.5L driveline parts from harmonic strain

Pacifica V6 Combustion Operational Limits

Operating lubricant pressure produces 18 to 22 PSI during warm idle and expands to 45 through 60 PSI at 2600 RPM cruise speeds. Internal coolant temperatures stabilize between 190°F and 205°F using factory thermostat ratings. This 3.5-liter SOHC V6 generates 250 horsepower at 6400 RPM and 250 lb-ft continuous torque at 3900 RPM with a 10.0:1 compression ratio. Cylinder cranking pressure measures between 165 and 180 PSI across all six chambers. The cooling system rejects 2850 BTU per minute during full-throttle highway transit.

Pacifica Crankshaft Transaxle Alignment Thresholds

A 6-bolt rear crankshaft flange mounts flush to factory automatic transaxle flexplates. Measured crankshaft thrust endplay checks out between 0.0030 and 0.0070 inches. The 1.102-inch front crankshaft snout features a single keyway to position the timing belt drive gear and harmonic balancer, holding true serpentine accessory belt pulley alignment.

Pacifica Fleet Lubricant Priming Guidelines

Technicians must prime the engine oil pump prior to first startup by cranking the starter without ignition until oil pressure warning lamps extinguish. Fill the crankcase with 5W-30 or 10W-30 motor oil meeting Chrysler MS-6395 standards. This production engine is not engineered for turbocharging exceeding factory parameters, nitrous injection, or competitive circuit 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 3500 miles during commercial transit cycles

Pacifica Commercial Warranty Shipment Details

Commercial fleet accounts 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.
