Honda Accord F23A5 2.3L L4 Engine 12466E 1998-2002

Front oil pump seal extrusion and crank angle sensor harness chafing cause sudden ignition failure across fleet transport cars. The Honda Accord F23A5 2.3L L4 Engine 12466E resolves crank position signal dropout during commercial long block repower overhauls. This 4-Cylinder 135HP non-VTEC powerplant requires crank sensor air gap inspection before securing lower timing gear sprockets.

Cast A356-T6 aluminum forms the open-deck block casting displaying driver and passenger side PAA identification stamps. Centrifugal cast iron liners house anti-friction coated pistons linked to a 4140 forged steel crankshaft spinning on tri-metal bearings. This Honda engine core demands a 12V 140A starter draw during cold cranking tests. The crated motor weighs 180 lbs dry, occupies a 24in length, 23in width, 25in height stance, and requires 4.5 quarts of oil.

Key Features of Honda Accord F23A5

Fleet maintenance controllers buy Honda Accord F23A5 2.3L L4 Engine 12466E packages to restore company sedans without parts delay. Every industrial engine rebuild arrives with pre-installed timing gears, balance shaft belt, primary timing belt, mechanical tensioner, and water pump hardware.

- Cylinder bores machine to 3.386in with diamond plateau hone surface finishes.
- Main bearing journal clearance holds at 0.0014in across the five-bearing crankcase.
- Crankshaft position sensor mounts to the oil pump housing for accurate trigger alignment.
- Pre-installed water pumps eliminate front-end cooling system installation bottlenecks.
- Reinforced multi layer steel head gaskets stop combustion blowby into water jackets.
- This F23A5 commercial core features cylinder head decks surfaced flat to 0.0003in.
- Stellite faced exhaust valves resist seat recession under sustained highway travel.

Dynamometer Load Station Records

Automated brake cell test logs demonstrate that this F23A5 long block engine generates 135 continuous BHP and 145 ft-lbs of torque at 4400 continuous load RPM. Internal oil gallery pressure measures 54 PSI with oil sump temp remaining at 191°F under full thermal loading. Exhaust gas temp tops at 1240°F down the test header runners. Cylinder compression reads between 175 PSI and 182 PSI across all four chambers. Crankshaft center journal runout holds within 0.0002in TIR.

Chassis Placement Setup Boundaries

Automatic transmission throttle kickdown cables demand 5 lbs of linear pull force to guarantee correct transmission downshift response under load. This non-VTEC engine is not engineered for high-boost turbo track cars, marine stern propulsion, or commercial refrigeration pump skids.

- Drain initial break-in petroleum motor oil after 500 miles or 30 run hours.
- Inspect cold intake valve clearance at 0.010in and exhaust clearance at 0.012in.
- Torque cylinder head fasteners in three stages to 76 ft-lbs final specification.
