International DT570
Diesel Truck Engines

The International DT570 is a proven choice across school bus, medium-duty, and regional vocational fleets. JSJ Diesel supports both used take-outs and full rebuilds for this platform and can help you match the right engine to your chassis, emissions requirements, and duty cycle.

Selecting the correct DT570 for your application is less about chasing a single “best” variant and more about aligning software families, harness connectors, turbo and EGR (if equipped), and your cooling package.

Fitment & Architecture — What to Verify First

  • 1
    ECM family & connectors: Match ECU generation and main connectors to your cab harness.
  • 2
    Emissions package: Pre-EGR vs. EGR vs. DPF/DEF changes turbo routing, sensors, and legality.
  • 3
    Cooling package: Radiator condition, shroud alignment, fan clutch health, and thermostat housing orientation.
  • 4
    Charge-air integrity: Pressure-test the CAC to 20–30 psi and replace suspect boots.
  • 5
    SAE fit: Verify flywheel housing size, mounts, accessory brackets, and belt routing.

Used Take-Out or Rebuild — Which Is Right for You?

  • 1
    Clean used take-out: Fast when documented: ECM screenshots, oil analysis, before-pull video/dyno, and clear tag photos.
  • 2
    In-frame / out-of-frame rebuild: Best for long-term service life and predictable intervals.
  • 3
    Hybrid approach: Drop a good long block, refresh water pump, oil cooler, turbo, and high-failure sensors.

Pre-Buy Checklist (Save Time on the Stand)

  • 1
    VIN / ESN & ECM: Record hours/miles, rating, faults; photograph each page.
  • 2
    Fuel & oil analysis: Watch for coolant, fuel dilution, silicon, and wear metals.
  • 3
    Turbo health: Endplay/spin checks; pair with a clean CAC.
  • 4
    Aftertreatment baseline: DPF ash load, regen history, dosing/NOx sensors, differential pressure.
  • 5
    Cooling sanity: Fan control, shroud fit, radiator condition.

Troubleshooting Patterns We See

  • 1
    Pull feels weak: Re-test CAC hot; check exhaust backpressure from damaged mufflers or collapsed flex.
  • 2
    Intermittent faults: Inspect loom for chafe at brackets/heat shields and clean grounds.
  • 3
    High EGTs: Verify fan clutch engagement and shroud alignment before parts-chasing.
