Detailed Description
Built for the 2021-2024 Ford Bronco Sport, CSF 3962 follows an OEM-style plastic tank and aluminum core layout to match the original cooling system architecture. The cross-flow configuration and factory-sized 1 5/16-inch inlet and outlet connections support proper coolant routing, while the single-row core is sized for the vehicle’s radiator opening and packaging requirements. CSF manufactures radiators to high-performance standards and validates cooling performance through laboratory wind-tunnel testing. This part cross-references Ford OE numbers LX6Z 8005 K and LX6Z 8005 S for the same application.
Common Cooling System Issues
- Coolant leaks from cracked tanks or aged seams
- Overheating caused by reduced radiator efficiency
- Restricted coolant flow from internal wear or contamination
- Physical damage to the radiator core from road debris
- Temperature instability during daily driving or stop-and-go use
Installation Notes and Tips
Verify inlet and outlet orientation before installation: this radiator uses a left-side inlet and right-side outlet. Confirm all hose connections, mounting points, and surrounding cooling components are in good condition before refilling the system. The radiator cap is not supplied, and the unit does not include an oil cooler.
