Detailed Product Overview

This One Stop Solutions condenser, part number 3689, is engineered around OE-style dimensions and mounting requirements. Core measurements are 16 mm thick, 660 mm wide, and 380 mm long, with a parallel flow layout that supports consistent A/C system performance. The aluminum construction and brazed fin-and-tube assembly are selected to improve thermal transfer and durability in daily-driven Subaru vehicles, including WRX and Impreza platforms.

This part cross-references Spectra Premium 7-3689 for the same application.

Common A/C System Issues

• Front-end condenser damage from road debris or minor impact
• Reduced cooling performance from internal restriction or leakage
• Corrosion or fatigue in older high-mileage A/C systems
• Loss of refrigerant pressure caused by failed condenser tubes or joints
• Uneven cabin cooling in Subaru WRX, WRX STI, Forester, Impreza, Crosstrek, and XV Crosstrek models

Installation Notes and Tips

Verify block fitting connections, core dimensions, and vehicle coverage before installation. Replace any damaged seals or O-rings during service, and evacuate and recharge the system according to factory procedures after the condenser is installed. Confirm that the condenser is seated correctly and that airflow paths are clear before returning the vehicle to service.

Quality Assurance

Each condenser is individually pressure tested and built with premium aluminum materials for consistent fit and heat dissipation. The design is intended to address common OE condenser failure points and support long-term service in higher-mileage Subaru vehicles.
