Precision Remanufacturing for Paccar MX Engines
The Paccar 1922163PE EGR Cooler is a full-scale OEM-grade rebuild engineered for 2014–2017 MX-13 enginespowering Kenworth T680/T880 and Peterbilt 579/567 trucks. Designed to control exhaust gas temperatures under heavy load, this cooler is remanufactured to meet or exceed Paccar OE flow and pressure standards. Every Turbo Kings rebuild ensures the same balance of reliability, efficiency, and emission compliance that fleets expect from new-engine components.
Each core undergoes complete disassembly and multi-stage cleaning to eliminate soot, carbon buildup, and coolant scale. Internal passages are processed through a heated alkaline detergent cycle, restoring unrestricted gas flow without damaging brazed joints. The unit then proceeds to a citric-acid descaling bath that re-exposes clean metal surfaces and maximizes heat-transfer capability. Once fully neutralized, all components are oven-baked to stabilize the alloy and prevent oxidation prior to assembly.
Critical joints, flanges, and welds are inspected under dye-penetrant and pressure-tested to 125 PSI, confirming absolute coolant and exhaust isolation. Each housing is TIG-welded using stainless filler matched to Paccar’s OE metallurgy, reinforcing weak points that commonly fail in high-duty cycles. The result is a cooler that restores factory performance and durability while extending lifespan beyond standard OEM service intervals.
What Makes a Turbo Kings Rebuild Different
Turbo Kings’ remanufacturing process is more than just cleaning—it’s a full engineering restoration. Each MX-series cooler is flow-bench validated to verify balanced exhaust distribution and coolant recovery rates. Our temperature-controlled alkaline and acid baths operate under precisely monitored pH levels to avoid metal erosion and ensure 100 % carbon removal.
After repair and re-welding, every unit’s sealing surfaces are resurfaced and alignment-checked for perfect gasket mating to the MX-13 head and exhaust manifold. Each cooler is then serialized and recorded for quality traceability before it’s primed with corrosion-inhibiting film and packaged for delivery.
