Denso 475-2072 A/C Expansion Valve

Denso New Expansion Valve 475-2072

Denso 475-2072 is a block-style A/C expansion valve that regulates refrigerant flow between the high- and low-pressure sides of the air conditioning system. For 2006-2009 Chevrolet Equinox and 2006-2009 Pontiac Torrent applications, it helps maintain proper evaporator performance and stable cabin cooling.

Denso’s New Expansion Valve line focuses on correct refrigerant metering for OE-style service work. This part cross-references Chevrolet 19129828 for the same application.

Key Features

• Block valve design for A/C refrigerant control
• Helps separate suction and discharge sides of the system
• Supports proper evaporator heat exchange
• Built for 2006-2009 Chevrolet Equinox and 2006-2009 Pontiac Torrent fitment
• Part number 475-2072 for catalog and service matching

How It Works

The expansion valve meters liquid refrigerant into the evaporator based on system demand. When calibration is correct, the evaporator can absorb heat efficiently and the A/C system can deliver consistent cooling. If the valve is out of spec, the evaporator may not exchange heat properly or can freeze, which can lead to additional A/C system damage.

Common Issues This Part Can Address

• Weak or inconsistent air conditioning output
• Evaporator icing or freeze-up
• Improper refrigerant flow through the evaporator
• Poor cabin cooling in Chevrolet Equinox and Pontiac Torrent models
• A/C performance problems tied to a faulty expansion valve

Installation Notes

Verify system diagnosis before replacement and confirm the valve matches the vehicle’s A/C configuration. For 2006-2009 Chevrolet Equinox, N/A position fitment applies; for 2006-2009 Pontiac Torrent, N/A position fitment applies. Always inspect the surrounding A/C components and follow proper evacuation and recharge procedures after service.

Quality Assurance

Denso draws on decades of OE-level A/C engineering for automakers, and the 475-2072 is built to meet the calibration needs of the vehicle’s air conditioning system. Use the part number 475-2072 to confirm the correct expansion valve for your application.
