Optimize your Caterpillar C15 or 3406E engine’s cooling system with the Kustom Truck Stainless Braided Hose Kit, specifically designed for 70 Pin engines with 2WS, 1MM, 6NZ, 7CZ, or MBN serial prefixes. This innovative kit enhances coolant flow efficiency, addressing the standard coolant path’s temperature disparities by injecting coolant directly into cylinder #4 from the oil cooler, in addition to the rear entry at cylinder #6. By routing coolant to cylinder #4, the kit mitigates the hot spot created by the turbo over cylinders #3 and #4, resulting in more consistent and efficient coolant temperatures across all six cylinders. Crafted from high-quality stainless braided hoses, the kit includes a Cylinder Block Cover Plate with two ports, a gasket, two coolant supply lines from the rear water bonnet to cylinder #4, and a set of stainless steel fittings for secure, leak-free connections. The stainless braided hoses offer superior durability, high temperature resistance, and a sleek, mirror-polished finish that enhances your engine bay’s aesthetics. Ideal for mechanics, fleet owners, and truck enthusiasts upgrading Peterbilt, Kenworth, or Freightliner trucks, this kit ensures improved engine performance and longevity. Note: Compatible only with specified serial prefixes and Caterpillar Rear Bonnet PN: 163-9385. Confirm fitment with your specific engine configuration by contacting Kustom Truck for verification. Enhance your engine’s cooling efficiency with this precision-engineered hose kit, crafted for quality, performance, and style.
