Global Parts 3412035 A/C Expansion Valve - Front

A/C Expansion Valve for Volkswagen Applications

Global Parts 3412035 is an A/C expansion valve/orifice tube designed to regulate refrigerant flow before the evaporator. By slowing refrigerant at this point in the system, it helps the evaporator use cooling capacity more effectively. This part number 3412035 is a direct-fit service component for select Volkswagen Atlas, Atlas Cross Sport, Tiguan, and Tiguan Limited models.

Key Features

• Expansion valve/orifice tube for automotive air conditioning systems
• Controls refrigerant flow before the evaporator
• Supports efficient evaporator cooling performance
• Recommended replacement during A/C system service
• Fits front applications where listed in the vehicle fitment data
• Global Parts part number 3412035

Detailed Description

Global Parts 3412035 is built for vehicles that use an A/C expansion valve/orifice tube to meter refrigerant into the evaporator. This function is critical to stable cabin cooling, especially when servicing a system that has been opened for repairs. For Volkswagen Atlas and Volkswagen Atlas Cross Sport models, as well as select Tiguan applications, this part number 3412035 supports proper refrigerant control at the evaporator inlet.

This part cross-references Four Seasons 39618 for the same application. It also cross-references UAC EX10680C for the same application.

What It Helps Address

• Weak or inconsistent A/C cooling output
• Improper refrigerant metering at the evaporator
• Service-related A/C performance loss after system opening
• Reduced cooling efficiency in Volkswagen Atlas, Atlas Cross Sport, and Tiguan applications
• Need for a replacement expansion valve during A/C repair
