Spectra Premium CU2376 radiator for the 2004-2006 Toyota Tundra V8 4.7L and other vehicles cools the engine's coolant as it flows through the core. Its structure and design are built to meet the same durability expectations as the OE radiator.
Coolant leaks at the core or tank seams, a coolant smell or an engine that runs hot can point to a failing radiator. A stuck thermostat, a tired water pump, a soft hose, a loose radiator cap or a cooling fan that no longer spins up can also be behind a hot-running engine, so find the cause before buying. This listing is one radiator, which is the quantity the engine takes.
This is a radiator for the 2001-2007 Toyota Sequoia V8 4.7L, and it also fits the 2004-2006 Toyota Tundra V8 4.7L.
