The Denso New Expansion Valve, part number 475-2093, regulates refrigerant flow between the high- and low-pressure sides of the A/C system. For 2010-2013 Mazda 3 models, this block valve helps maintain proper evaporator performance and stable cabin cooling.

Key Features

  • Block valve design for controlled refrigerant metering
  • Separates suction and discharge sides of the air conditioning system

Product Details

Denso expansion devices are built to manage refrigerant flow with the calibration required for consistent HVAC operation. When the valve is out of spec, the evaporator can lose efficiency or freeze, which can lead to poor cooling performance and added strain on the system. This Denso 475-2093 expansion valve is listed for 2010-2013 Mazda 3 applications and is also cross-referenced to Four Seasons 39347 for the same application.

What It Helps Address

  • Weak or inconsistent A/C cooling in a Mazda 3
  • Evaporator icing or freeze-up
  • Improper refrigerant metering through the evaporator
  • Loss of heat exchange efficiency in the HVAC system
  • Replacement needs for a worn or incorrect expansion valve

Installation Notes

Verify the vehicle year and HVAC configuration before ordering. This part is listed for 2010-2013 Mazda 3 models, and the fitment notes identify it as a new expansion valve. Inspect the surrounding A/C components, recover refrigerant properly, and confirm the system is clean and leak-free before final assembly. The part number 475-2093 should be matched to the vehicle application during service.

Quality Assurance

Denso draws on decades of A/C component and system engineering for automakers, and its expansion devices are built to meet the calibration demands of modern HVAC systems. For 2010-2013 Mazda 3 service, 475-2093 provides a direct-fit replacement path backed by Denso’s OE-focused product development.
