Description

International 1876444C94 EGR Cooler - Genuine International Hot-Side EGR Cooler for MaxxForce DT/9/10

The International 1876444C94 is the genuine hot-side (exhaust-side) EGR cooler for the MaxxForce DT, 9, and 10. It's the larger 330mm cooler that sits first in the EGR loop, taking raw exhaust gas straight off the engine and pulling the initial heat out before the flow moves on to the cold-side cooler.

Key Functions:

First-stage cooling of exhaust gas coming off the engine, on the hot side of the EGR loop

Fitment & Specifications:

- Application: International/Navistar MaxxForce DT, 9, 10, hot/exhaust side
- Position: hot side, 330mm (larger than the 260mm cold-side cooler)

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

Purpose of the Part

This is the cooler that takes the worst of the heat. Exhaust comes off the engine at full temperature and hits this unit first, so it carries the highest thermal load in the EGR system - and that's exactly why the hot side is a known crack point on MaxxForce engines. Once the tubes split, exhaust and coolant meet and the failure spreads fast.

Issue Symptoms / When to Replace

- Coolant surge tank pressurizing or bubbling - exhaust gas forced into the cooling system, the classic hot-side tell
- Coolant loss with no external leak
- White smoke and a sweet coolant smell
- Overheating or repeated low-coolant

Brand Information

A genuine International 1876444C94 is built to the MaxxForce hot-side spec - the size, flow, and flange fit for the highest-heat position in the EGR loop, where a mismatched cooler won't seal or survive. International (Navistar) builds trucks, buses, and MaxxForce diesel engines for commercial use.

Installation Notes

- Make sure you're getting the hot/exhaust 330mm cooler, not the smaller cold-side unit - they're not interchangeable.
- Because the hot side runs hardest, don't just swap it and move on - check why it failed and inspect the cold side too. Shops commonly do both coolers at once on these.
- If the failed cooler pushed exhaust into the coolant, pressure-test and flush the cooling system before running the new one.
- New gaskets on clean, flat sealing faces.

How to Identify an OEM Part

- Genuine units carry the International/Navistar part number - match it to your listing.
- Confirm it's the larger 330mm hot-side cooler before buying, not the 260mm cold side.
