Denso 475-2105 A/C Expansion Valve - Rear

Denso New Expansion Valve 475-2105

Denso 475-2105 is a block-style A/C expansion valve for the rear air conditioning circuit. It regulates refrigerant flow into the evaporator so the system can separate high- and low-side pressure correctly and maintain stable cooling performance.

Built for Toyota applications, this Denso New Expansion Valve is a direct-fit service part for rear A/C repair on select Sienna and Highlander models. The 475-2105 part number is a practical match when replacing a worn or inaccurate rear expansion valve in the HVAC system.

Key Features

• Block valve design for rear A/C refrigerant control
• Regulates liquid refrigerant flow through the evaporator
• Helps maintain proper high-side and low-side separation
• OE-style replacement for select Toyota rear HVAC systems
• Cross-references Four Seasons 39333 and Global Parts Distributors LLC 3411849 for the same application

Product Details

Denso’s New Expansion Valve line focuses on accurate refrigerant metering, which is critical to evaporator performance. When calibration is off, the evaporator can lose heat-exchange efficiency or freeze, leading to poor cabin cooling and added strain on the A/C system. This part is engineered for rear A/C service on 2011-2016 Toyota Sienna and 2008-2013 Toyota Highlander applications, with fitment that includes rear-position HVAC use. The 475-2105 is also referenced by Toyota part numbers 88515-0E110, 88515-08120, and 88515-28200.

What It Helps Fix

• Weak or inconsistent rear A/C cooling
• Evaporator icing or freeze-up
• Incorrect refrigerant metering at the evaporator
• Pressure imbalance between high and low sides
• Poor rear cabin temperature control in Toyota Sienna and Highlander models

Installation Notes

Fits 2016 Toyota Sienna, rear; rear A/C, to 12/2015; New Expansion Valve. Fits 2011-2015 Toyota Sienna, rear; rear A/C Expansion Valve; New Expansion Valve. Fits 2008-2013 Toyota Highlander, rear; rear A/C Expansion Valve; New Expansion Valve.

Confirm the rear HVAC configuration and compare the existing valve style before installation. Proper evacuation, leak checking, and refrigerant recharge are required after A/C component replacement. Verify the system is clean and free of contamination so the new valve can meter refrigerant correctly.

Quality Assurance

Denso draws on decades of A/C system engineering experience for automakers, and this expansion valve is built to support correct refrigerant control in the specified Toyota rear A/C applications.
