Detailed Description

Koyorad A2376 is a radiator replacement designed around OE-equivalent specifications for the cooling system in 2001-2007 Toyota Sequoia and 2005-2006 Toyota Tundra models. The aluminum core helps transfer heat efficiently, while the plastic tank design follows common factory construction used in many original equipment radiators. With a 2-row core and an included internal transmission oil cooler, this unit addresses both engine coolant temperature control and automatic transmission fluid cooling in one assembly.

Koyorad builds replacement radiators with the technical experience needed to match the original application closely, making the A2376 a practical choice when servicing a Toyota Sequoia radiator or Toyota Tundra radiator application. The part number A2376 is useful when verifying the correct replacement before installation.

What This Radiator Helps Address

• Coolant leaks from a cracked or aging radiator tank
• Restricted cooling performance from a clogged or corroded core
• Transmission fluid temperature issues related to a failing cooler circuit
• Overheating caused by reduced heat exchange efficiency
• Physical damage to the radiator from road debris or wear

Installation Notes and Tips

Confirm radiator dimensions, inlet and outlet sizes, and transmission cooler connections before installation. Flush the cooling system and inspect hoses, clamps, and related components for wear before fitting the new unit. For Toyota Sequoia and Toyota Tundra applications, verify that the transmission cooler lines and mounting points match the original radiator configuration. The part number A2376 should be checked against the vehicle’s existing radiator and build details before service.

Quality Assurance

Koyorad manufactures OE-style replacement radiators using application-specific engineering and cooling-system experience. The A2376 is built to serve as a direct replacement for the listed Toyota fitments with the specified core construction and integrated transmission oil cooler.
