FL-151906

• 36 × 36¾ in aluminum core offers OE heat-rejection capacity for Cummins ISX, PACCAR MX-13, and Caterpillar C15 engines used in these conventional cabs.
• Left-in / right-out hose layout mirrors factory plumbing on both Peterbilt and Kenworth chassis, minimizing hose crossings and clamp points.
• Remote surge tank keeps the top tank low, allowing the sloped hood lines of the 384/386 and providing clear sight lines over the W900’s long hood.
• No in-core oil cooler simplifies service; fleets continue using the stand-alone transmission or engine-oil heat exchanger supplied by the OEM.
• Frame flexibility lets technicians reuse intact side rails or order framed variants for quicker collision repair and better side-support alignment.

Heavy-duty replacement radiator engineered for 2008-up Peterbilt 384/386 and Kenworth W900 trucks. The FL-151906 family features a 36 × 36.75 × 2-in aluminum core, 2.5-in left-hand inlet, 2.5-in right-hand outlet, and surge-tank cooling architecture. Bare, bolt-on-frame, and welded-frame versions cover routine maintenance through severe-duty collision repairs while preserving OEM airflow and durability.
