1469445 Manifold-Exh Fits Caterpillar Models

One New Aftermarket Replacement Exhaust Manifold for Caterpillar (Cat) 3406E, C15, and C16 Diesel Engines

This three-piece cast-iron exhaust manifold collects combustion gases from all six cylinders and routes them to the turbocharger in Caterpillar 3406E, C15, and C16 heavy-duty diesel engines. The three-section design -- two end sections and a center section -- allows for thermal expansion and contraction during heat cycles, reducing stress on the manifold body and mounting hardware. Engineered as a direct-fit aftermarket replacement for OEM part number 1469445 (also formatted as 146-9445), this manifold is used in the air inlet and exhaust system of these Cat engines.

Note: For use with turbocharger exhaust 12.5 degrees below horizontal. This manifold applies to the early (pre-ACERT) C15 configuration. Verify engine serial number prefix before ordering.
