EGR Cooler Kit for International CXT (2005-2008) 7.6L 9.3L

Heavy-Duty Stainless EGR Cooler Kit for 2005-2008 International CXT (7300 Chassis)

What it Does: The EGR Cooler Kit replaces the failure-prone factory heat exchanger on the 2005-2008 International CXT to lower recirculated exhaust gas temperatures and eliminate internal coolant leaks into the intake and exhaust streams.

The Stock International CXT Thermal Fatigue Failure

The original round heat exchanger on the Navistar DT466 and DT570 engines experiences extreme thermal shock during heavy hauling. Factory internal brazed passages crack under sustained 1,200°F exhaust temperatures counterflowing against pressurized coolant. When these thin internal core tubes rupture, coolant seeps directly into the exhaust tract, causing persistent coolant consumption, dense white exhaust smoke, cooling system over-pressurization, and EGR delta-pressure trouble codes.

The Engineering Solution

Engineered as an exact-fit replacement for OEM part 1871733C92 and 1871733C93, this 11.5-inch round EGR cooler is fabricated with high-grade stainless steel internal tubing designed to endure thermal expansion cycles without cracking. The unit restores proper thermal transfer to lower intake charge temperatures without restricting exhaust gas recirculation flow. Supplied with a heavy-duty coolant transfer pipe, structural mounting clamp, exhaust gaskets, and high-temperature Viton O-rings, it allows technicians to complete a leak-free repair in a single service bay visit.
