2004-2011 Mitsubishi Eclipse Vin F 4G69 2.4L Remanufactured Engine

Description

Propel regional courier transport coupes and municipal fleet service sedans across continuous multi-stop urban transit routes under 170 PSI cylinder compression force without detonation through the Mitsubishi Eclipse 4G69 Remanufactured Engine engineered for 2004 to 2011 Mitsubishi Eclipse VIN F commercial fleet vehicles. This SOHC 16-valve MIVEC 2.4-liter platform restores broad mid-range pulling torque, quiet valvetrain operation, and dependable service.

Cast from high-density cast iron, this rigid closed-deck block halts cylinder bore distortion under continuous thermal cycling. A forged steel crankshaft operates within micro-grooved tri-metal bearings, connected to forged steel connecting rods and graphite-coated hypereutectic pistons. Cylinder bores feature a 45-degree diamond plateau hone below an Ra 30 micro-inch deck surface finish. Dry mass measures 330 lbs, complemented by a 4.5-quart capacity wet sump steel oil pan.

Key Features of Mitsubishi Eclipse 4G69

Commercial vehicle managers buy Mitsubishi Eclipse 4G69 remanufactured engine packages to eliminate chronic fleet downtime and extend chassis service longevity. Each remanufactured long block undergoes vacuum decay testing to guarantee total oil and coolant circuit separation.

• MIVEC variable valve timing mechanisms optimize intake valve lift to enhance low-end engine torque
• Twin counter-rotating balance shafts cancel second-order vibrations to improve driver cabin comfort
• 0.0013 to 0.0020 inch rod bearing oil clearances prevent bearing scuffing during hot idling
• Multi-layer steel cylinder head gaskets maintain combustion seals under extreme municipal summer heat
• High-flow internal trochoid oil pumps route pressurized lubricant to overhead hydraulic lash adjusters
• Hardened intake and exhaust valve guides prevent valve guide wear and stem play
• Dynamic balancing validates Mitsubishi Eclipse 4G69 internal rotating components to prevent driveline vibration

Eclipse MIVEC Combustion Operational Limits

Lubricant pressure maintains 16 to 22 PSI at warm idle and increases to 45 through 60 PSI at 2800 RPM. Operating coolant temperatures stay between 185°F and 200°F through regulated cross-flow cooling circulation. The 2.4-liter MIVEC engine outputs 162 horsepower at 6000 RPM and 162 lb-ft continuous torque at 4000 RPM with a 9.5:1 compression ratio. Cylinder cranking compression confirms 165 to 180 PSI across all four chambers. The cooling system evacuates 2100 BTU per minute during highway driving.

Eclipse Crankshaft Transaxle Alignment Thresholds

A 7-bolt rear crankshaft flange aligns true with factory automatic flexplates and manual transaxle flywheels. Internal thrust washers regulate crankshaft endplay between 0.0030 and 0.0070 inches. The 0.984-inch crankshaft snout carries a dedicated keyway for timing sprocket alignment, preventing timing belt slip during sudden transmission shifts.

Eclipse Fleet Lubricant Servicing Protocols

Technicians must prime the lubrication system using clean motor oil prior to first startup. Fill the crankcase with 5W-20 or 5W-30 motor oil meeting current API service classifications. This production unit is not engineered for turbo conversions exceeding factory boost limits, nitrous oxide systems, or demolition derby racing use.

• Inspect 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 3000 miles during commercial transit cycles

Eclipse Commercial Warranty Shipment Inclusions

Fleet accounts receive a 3-Year / 100,000-Mile commercial fleet warranty covering cylinder block, cylinder head, 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, dyno report, and pre-lubrication instructions.
