Product Line Details
CSF’s 1 Row Plastic Tank Aluminum Core line focuses on OE-style radiator construction with plastic end tanks and an aluminum heat exchanger. This design supports factory fitment on vehicles that use a cross flow layout and integrated oil cooler connections, including Volvo S70, Volvo V70, and Volvo 850 applications.
Detailed Description
CSF 3331 is a replacement radiator for 1998 Volvo S70, 1998 Volvo V70, and 1993-1997 Volvo 850. The radiator uses an aluminum core for heat transfer efficiency and plastic tanks to match the original equipment style. Its cross flow configuration, 1-row core, and quick-connect oil cooler fittings are built around the factory layout for these Volvo cooling systems. This part cross-references APDI 8012099 and AP Exhaust 2100 for the same application.
Common Cooling Issues Addressed
- Leaking radiator tanks or seams
- Restricted coolant flow from an aging core
- Transmission oil cooler connection wear at the radiator
- Overheating caused by reduced heat dissipation
- Cracked or brittle OE-style plastic end tanks
Installation Notes and Tips
Verify inlet and outlet orientation before installation: inlet is 1 3/8 in. on the right and outlet is 1 3/8 in. on the left. Confirm the vehicle uses the OE-style plastic tank and aluminum core layout with quick-connect oil cooler fittings. Inspect hoses, clamps, and coolant condition during radiator replacement to complete the cooling system service properly.
Quality Assurance
CSF manufactures radiators to high-performance standards in ISO/TSO-certified facilities and validates designs through wind tunnel testing for cooling performance. With decades of production experience and broad OE-style coverage, CSF 3331 is built for dependable replacement use on Volvo S70, Volvo V70, and Volvo 850 cooling systems.
