There isn't a single engine—the International 4700 has been offered with several powerplants across its production, depending on year and market. Common options include the DT466 family, Cummins ISB, and Navistar's MaxxForce lineup.
Common engine offerings over the years
These engines were among the most frequently installed in 4700 models across different eras and regions.
- DT466/DT466E inline-six diesel (approximately 7.6 L) — long-standing option in early to mid-1990s and early 2000s 4700s.
- Cummins ISB family (5.9 L, later 6.7 L) — used on some late-1990s to early-2000s configurations as an alternative to Navistar powertrains.
- Navistar MaxxForce 7 (6.4 L V8) — introduced in the late 2000s in some 4700/4300 options for emissions compliance and modern power delivery.
- Navistar MaxxForce 9 (9.0 L inline-six) — used in certain 4700 configurations in the early- to mid-2010s for higher torque and emissions alignment.
Configurations vary by model year, region, and application, so not every engine is available in every 4700. The exact engine can be confirmed from the vehicle's VIN, engine plate, or build documentation.
Identifying the engine in your International 4700
To determine the precise engine in a given truck, check these sources and indicators.
- VIN and build codes — the engine family is often specified in the VIN or option sheet.
- Engine identification plate — a tag on the engine or its valve cover showing engine family and displacement.
- Original window sticker or owner's manual — lists the installed engine option.
- Physical characteristics — inline-six vs. V8, turbo layout, exhaust after-treatment, and intake style can indicate the family.
When in doubt, contact an International/Navistar dealer or a qualified diesel technician who can read the VIN and confirm the exact engine model and specifications.
Why engine options changed over time
Navistar updated engines to meet evolving emissions standards, fuel economy targets, and serviceability. The shift from older DT-series engines to MaxxForce powertrains reflected regulatory changes and a drive for improved reliability and performance in medium-duty applications.
Summary
The International 4700 has seen several engines over its production life. The most common options include the DT466 family, Cummins ISB variants, and Navistar MaxxForce engines such as the 6.4L V8 (MaxxForce 7) and 9.0L inline-six (MaxxForce 9). Exact engine matching depends on year and configuration; verify with VIN/build documentation or a Navistar technician for accuracy.
