Core Sub-Assembly

About this product

Part of the Radiator & Water Outlet system, the Core Sub-Assembly (#16403-74550) plays a crucial role in the engine-fuel operation of your Toyota vehicle. It helps regulate the engine's temperature, preventing overheating and promoting optimal performance. The assembly, consisting of a series of tubes and fins, circulates coolant to absorb the engine's heat before discarding it out to the atmosphere.
