Detailed Description

One Stop Solutions 98734 is an HVAC heater core designed as a direct replacement for original Volvo heater core applications. It uses aluminum construction in place of copper-style designs and includes the foam and accessories needed to match OE fit and function. The core is individually pressure tested before release, and the tube plating is used to help reduce corrosion-related failure. This makes it a practical choice for Volvo heating repairs where the original core has leaked, restricted flow, or lost heat output. This part cross-references Spectra Premium 94734 for the same application.

What It Helps Fix

• Loss of cabin heat in Volvo S90, V90, 960, 940, 740, 780, 760, and 745 vehicles
• Coolant odor or fogging caused by a leaking heater core
• Restricted coolant flow through a clogged heater core
• Heat output problems from age-related internal corrosion
• Repeat failure in high-mileage HVAC systems
