Acura Honda F23A1/A4 2.3L L4 Remanufactured Engine – 1998-2002

Description

Halt balance shaft belt failure, eliminate valve guide oil leakage under continuous commercial cruising, and hold 50 PSI hot cruise oil pressure across demanding fleet routes using the Honda Acura F23A 2.3L Remanufactured Engine engineered for 1998 to 2002 Honda Accord and Acura CL commercial fleet vehicles. This SOHC VTEC platform restores high low-end pulling torque and dependable multi-shift service.

Cast from high-density aluminum alloy with cast-in iron cylinder liners, this deep-skirt F23 block incorporates an open-deck layout and a structural lower main bearing cap bridge that halts bottom-end deflection. A micro-polished forged steel crankshaft turns within tri-metal bearings, linked to forged steel connecting rods and graphite-coated hypereutectic aluminum pistons. Cylinder decks receive an Ra 30 finish for MLS gasket sealing. Dry mass measures 320 lbs with a 4.5-quart capacity stamped steel oil pan.

Key Features of Honda Acura F23A

Administrative fleet directors buy Honda Acura F23A remanufactured engine packages to keep commercial executive sedans and administrative passenger cars running on strict operational schedules. Every remanufactured long block undergoes vacuum decay testing to guarantee total fluid circuit separation before crate departure.

• Single overhead camshaft VTEC mechanisms switch intake valve timing at 2500 RPM under load
• Twin counter-rotating balance shaft mechanisms cancel four-cylinder secondary vibrations during high-speed cruising
• 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 transit heat
• High-flow internal trochoid oil pumps channel pressurized lubricant to overhead rocker arm shafts
• Induction-hardened valve seats prevent valve face recession during sustained highway cruise operations
• Precision rotating package balancing protects Honda Acura F23A driveline parts from vibration

F23A Operational Combustion Limit Ratings

Operating lubricant pressure produces 16 to 22 PSI during warm idle and expands to 50 through 65 PSI at 2600 RPM cruise speeds. Internal coolant temperatures stabilize between 188°F and 202°F through regulated cross-flow cooling circulation. This 2.3-liter SOHC VTEC engine generates 150 horsepower at 5700 RPM and 152 lb-ft continuous torque at 4900 RPM with a 9.3:1 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.

F23A Crankshaft Transaxle Alignment Thresholds

An 8-bolt rear crankshaft flange mounts flush to factory automatic transaxle 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.

F23A Fleet Lubricant Servicing Protocols

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-20 or 5W-30 motor oil meeting API service standards. This production engine is not engineered for turbocharging conversions, nitrous injection, or competitive track 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 3750 miles during commercial transit cycles

F23A 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.
