International MaxxForce 11 / 13 (2011 – 2014) EGR Cooler
Rebuilt for Endurance Under High-Heat Load
The Turbo Kings Remanufactured EGR Cooler for International MaxxForce 11 and 13 (2011 – 2014) restores OEM-grade exhaust-gas temperature control while addressing the chronic coolant-to-exhaust leaks these engines are known for. Designed for ProStar, TranStar, and WorkStar applications, this cooler pair has been rebuilt to handle sustained duty cycles and the thermal cycling stress of MaxxForce’s variable-geometry turbo system.
Each core is fully disassembled, chemically stripped, and ultrasonically cleaned to eliminate carbon, soot, and oil contamination from internal fin passages. Turbo Kings then subjects the units to a dual-phase chemical bath — an alkaline degreasing stage followed by an acidic descaling flush — which restores internal stainless-steel surfaces to bare metal condition. End housings are TIG-weld reinforced using 309L stainless filler for superior vibration resistance and leak prevention.
After reassembly, every cooler is pressure-tested to 125 PSI on both the coolant and exhaust sides to ensure 100 % circuit separation. Mating flanges are precision-surfaced to OEM flatness for gasket-tight sealing, and each unit is oven-cured to relieve weld tension and stabilize the alloy prior to packaging.
What Makes a Turbo Kings Rebuild Different
Turbo Kings rebuilds go beyond factory specifications by solving the inherent stress-crack and hot-spot issues that plagued the original Navistar design. Weak weld areas are reinforced with a bead-overlay technique, and the transition seams between the upper and lower banks are stress-relieved to eliminate expansion fatigue.
Every unit is then flow-bench verified, confirming equalized exhaust distribution and coolant flow across all rows. This ensures consistent EGR temperature reduction, improved turbo efficiency, and reduced NOx output. Each cooler carries a unique serial ID recorded through Turbo Kings’ QA tracking system for complete rebuild traceability.
