VEGE Remanufactured DFYK 2.5L 152ci Premium Grade Long Block Engine

Description

Intake swirl valve screw ingestion and catalytic ceramic dust back-siphoning score cylinder walls in utility work vans. The VEGE Remanufactured DFYK 2.5L 152ci Premium Grade Long Block Engine eliminates catastrophic cylinder score through a commercial long block repower. This 2.5L 4-Cylinder DOHC build develops 175HP, but mechanics must verify thread-locking compound on intake swirl butterflies.

Cast from ASTM A319 aluminum alloy with cast-in iron liners, this VEGE engine core houses a 16-valve aluminum head and an induction-hardened forged steel crankshaft. Starter draw demands 150A on 12V circuits. Bare engine weight reaches 260 lbs inside 23in length, 22in width, 24in height dimensions holding 4.5 quarts oil.

Key Features of VEGE DFYK

Transit fleet managers buy VEGE Remanufactured DFYK 2.5L 152ci Premium Grade Long Block Engine assemblies to keep delivery vehicles operating without purchasing newer fleet models. Advanced multi-layer steel head gaskets lock combustion pressures inside cylinders to prevent coolant erosion between adjacent cylinder decks.

• Displacement measures 152ci utilizing a 3.504in bore and 3.937in stroke rotating assembly.
• Multi-layer steel cylinder head gaskets prevent combustion gas transfer across thin deck bridges.
• Dual overhead camshaft architecture provides rapid throttle response across urban traffic speeds.
• Cast-in iron cylinder liners maintain bore roundness under severe continuous engine temperatures.
• DFYK commercial core line-boring guarantees true crankshaft journal rotation under heavy loads.
• Hydraulic timing chain tensioners maintain constant chain tension across fluctuating oil temperatures.
• Phosphated piston skirts resist cold scuffing during harsh sub-zero warehouse departures.

Bench Dynamometer Load Statistics

Dyno validation confirms mechanical parameters on each DFYK long block engine before shipping. The engine develops 175HP at 6000 RPM and 180 ft-lbs torque at 4000 RPM. Oil gallery pressure maintains 52 PSI hot at 195°F oil temperature. Cylinder compression balances out at 180 PSI across all cylinders with 3% variance. Crank runout limits to 0.0003in TIR. Exhaust gas temp tops out at 1260°F under full load.

Operational Exclusions Setup Protocols

Electronic throttle pedal pull resistance checks out at 4 lbs force. This DOHC four-cylinder engine is NOT designed for turbocharged conversions, longitudinal rear-wheel-drive configurations, or machinery running non-synthetic engine oils.

• Perform break-in oil and filter changes following the initial 500 miles of highway driving.
• Inspect intake manifold power valve screws and butterfly linkages after the first 50 operating hours.
• Check cam cover perimeter fastener torque to 8 ft-lbs following initial temperature cycles.

Warranty Statement Shipping Hardware

Built under strict VEGE assembly standard protocols, this remanufactured powertrain includes a 3-Year 100,000-mile commercial warranty. Uncrating reveals the remanufactured long block core, oil pan, timing cover, cam covers, oil pump pickup screen, and certified test sheet.
