Denso 475-2104 A/C Expansion Valve

Denso 475-2104 A/C Expansion Valve

Denso New Expansion Valve 475-2104 is a block valve for the air conditioning system on select Toyota Tundra models. It regulates refrigerant flow through the evaporator, helping maintain proper suction and discharge separation for stable A/C performance.

Built for 2007-2019 Toyota Tundra applications, this expansion valve supports correct evaporator operation when the original valve is restricted, inaccurate, or no longer controlling refrigerant flow as intended. Denso’s OE-focused engineering helps ensure the replacement matches the vehicle’s A/C system requirements.

Key Features

• Block valve design for automotive A/C refrigerant control
• Direct-fit replacement for select Toyota Tundra applications
• Helps maintain proper evaporator heat exchange
• Supports stable low-side and high-side system separation
• Denso part number 475-2104

Detailed Description

The expansion valve is a critical HVAC flow restrictor that meters liquid refrigerant into the evaporator. When calibration is off, the evaporator can lose heat-transfer efficiency or freeze, which can lead to poor cabin cooling and added strain on the system. Denso 475-2104 is engineered as a New Expansion Valve for the Toyota Tundra, with fitment covering 2007-2019 Toyota Tundra models. This part cross-references Toyota 88515-0C080 and 88515-0C110 for the same application.

Denso’s expansion devices are developed from decades of A/C system engineering for automakers, making this a practical OE-style replacement for Toyota Tundra A/C service. The part number 475-2104 is the reference to verify before ordering.

What It Helps Solve

• Weak or inconsistent cabin cooling
• Evaporator icing or freeze-up
• Incorrect refrigerant metering at the evaporator
• A/C performance loss caused by a worn or inaccurate valve
• System imbalance between suction and discharge sides

Installation Notes and Tips

Confirm the vehicle year and application before installation. For 2007-2019 Toyota Tundra service, verify the existing valve style and compare the replacement to the original part number 475-2104. Proper A/C service procedures, refrigerant recovery, evacuation, and leak checking should be followed during replacement.

Quality Assurance

Denso supplies A/C components engineered for vehicle-specific fitment and system calibration. This expansion valve is built to support correct refrigerant control in the Toyota Tundra HVAC system.
