Denso 475-2099 A/C Expansion Valve - Rear

Denso A/C Expansion Valve for Rear HVAC

Denso New Expansion Valve 475-2099 is a block-style A/C expansion valve for rear HVAC systems. It regulates refrigerant flow into the evaporator, helping maintain proper suction and discharge separation in the air conditioning circuit. For rear A/C service on Chrysler Town & Country, Dodge Grand Caravan, and Volkswagen Routan, this part number 475-2099 supports accurate refrigerant control where calibration matters.

Key Features

• Block valve design for automotive A/C flow control
• Separates low-side and high-side refrigerant flow at the evaporator
• Helps maintain correct evaporator temperature regulation
• OE-focused Denso New Expansion Valve line for replacement service
• Direct fit for rear A/C applications on select Chrysler, Dodge, and Volkswagen vehicles

Application Details

This Denso expansion valve is used in rear HVAC systems on 2008-2011 Chrysler Town & Country, 2008-2011 Dodge Grand Caravan, and 2009-2011 Volkswagen Routan. It is also listed for rear auxiliary A/C service on 2008 Chrysler Town & Country and 2008 Dodge Grand Caravan. The 475-2099 part number is a practical choice when replacing a rear A/C expansion valve on these vehicles and when restoring proper refrigerant metering at the evaporator.

Denso’s expansion devices are engineered for precise refrigerant control, which is important because incorrect calibration can reduce heat exchange performance or cause evaporator freeze-up. This part cross-references Four Seasons 39330 for the same application.

What It Helps Address

• Weak rear A/C cooling
• Evaporator freeze-up from incorrect refrigerant metering
• Uneven cabin temperature from poor rear HVAC performance
• Restricted or inconsistent refrigerant flow through the evaporator
• Replacement needs for a failed rear expansion valve

Installation Notes

Verify the vehicle’s rear HVAC configuration before ordering, since fitment is specific to rear and auxiliary A/C applications. Inspect the evaporator circuit, seals, and refrigerant lines during service, and confirm the system is evacuated and recharged according to factory procedures after installation. Match the valve type and application notes to the vehicle listing before replacing the original unit.

Quality Assurance

Denso draws on decades of A/C system engineering for automakers, and the New Expansion Valve line is built around correct application matching for service replacement. Use the listed fitment and part number 475-2099 to confirm the proper rear A/C expansion valve for your vehicle.
