1995 Hyundai Sonata G4AP 2.0L Remanufactured Engine

Description

Meet strict commercial fleet maintenance benchmarks with 305 lbs of precision-machined powertrain engineering that outputs dependable four-cylinder pulling power and thermal control throughout the Hyundai G4AP 2.0L Remanufactured Engine engineered for 1995 Hyundai Sonata commercial fleet sedans and cargo transport vehicles. This DOHC 16-valve Sirius-series long block package restores operational fuel efficiency across municipal transport routes.

Cast from high-density cast iron, this closed-deck cylinder block eliminates bore shift under continuous operational stress. 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 305 lbs, complemented by a 4.0-quart capacity wet sump oil pan.

Key Features of Hyundai G4AP

Commercial vehicle managers buy Hyundai G4AP 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.

• Dual overhead camshafts regulate sixteen valves to enhance mid-range engine torque efficiency
• 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 Hyundai G4AP internal rotating components to prevent driveline harmonic vibration

Hydraulic Thresholds Output Ratings

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 2.0-liter DOHC engine outputs 137 horsepower at 5800 RPM and 133 lb-ft continuous torque at 4000 RPM with a 9.0:1 compression ratio. Cylinder cranking compression confirms 160 to 175 PSI across all four chambers. The cooling system evacuates 1800 BTU per minute during highway driving.

Flywheel Pilot Alignment Specifications

A 6-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.

Lubricant Priming Fleet Maintenance

Technicians must prime the lubrication system using clean motor oil prior to first startup. Fill the crankcase with 10W-30 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

Commercial Fleet Warranty Manifest

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.
