Description

International 4307362R91 EGR Cooler - Genuine International Cold-Side EGR Cooler for MaxxForce DT/9/10

The International 4307362R91 is the genuine cold-side (intake-side) EGR cooler for the MaxxForce DT, 9, and 10. It's the shorter 260mm cooler that drops the temperature of recirculated exhaust on the intake side before it re-enters the engine, cutting combustion temps and NOx.

Key Functions:

- Cools recirculated exhaust on the intake side before it returns to the engine

Fitment & Specifications:

- Application: International/Navistar MaxxForce DT, 9, 10 (approx. 2008-2012), cold/intake side
- Position: cold side, 260mm (hot side is the larger 330mm cooler - different part)

Verify fitment with us before ordering to ensure the correct part for your application.

Purpose of the Part

It's the second-stage cooler on the intake side of the MaxxForce EGR loop. Recirculated exhaust runs through it, engine coolant pulls the heat out, and the cooled gas heads into the intake. These are a known failure point on MaxxForce engines - when the internal tubes crack, coolant and exhaust mix, and the problems start.

Issue Symptoms / When to Replace

- Coolant loss with no external leak - internal rupture
- Coolant showing up in the intake (cold-side tell)
- White smoke, sweet coolant smell
- Coolant surge tank pressurizing / pushing coolant - exhaust into the cooling system
- Overheating or low coolant

Brand Information

A genuine International 4307362R91 is built to the MaxxForce cold-side spec - correct length, flow, and flange fit - so it seals and cools where a mismatched cooler won't. International (Navistar) builds trucks, buses, and MaxxForce diesel engines for commercial use.

Installation Notes

- Confirm you're replacing the cold/intake side (260mm), not the hot side - they're different coolers.
- If the old one ruptured, flush the cooling system and check the intake for coolant before running the new one. On these engines it's common to replace both coolers and fix the root cause rather than swap one and be back in a month.
- Use new gaskets on clean, flat sealing faces.

How to Identify an OEM Part

- Genuine units carry the International/Navistar part number
- Confirm it's the cold-side 260mm cooler (shorter than the 330mm hot side) before buying.
