Detailed Description

The CSF 3965 radiator is engineered for the Kia Telluride and follows an OE-style layout with a plastic tank and aluminum core construction.

This radiator measures 28 3/8 in. long and 19 5/16 in. wide, with inlet and outlet dimensions sized for the listed Telluride application. Part number 3965 is a direct-fit cooling component for owners replacing a worn or leaking radiator on the Kia Telluride.
This part cross-references BBB Industries 13863 for the same application.
What This Radiator Helps Address
- Coolant leaks from a damaged or aging radiator
- Overheating caused by reduced heat transfer efficiency
- Cracked or deteriorated plastic tank assemblies
- Cooling system performance loss in daily driving conditions
- Replacement needs after impact or corrosion damage
Installation Notes and Tips
Verify inlet and outlet orientation before installation: inlet is on the right and outlet is on the left. Confirm all hose connections, mounting points, and the integrated oil cooler interface match the vehicle before final assembly. Flush the cooling system and inspect related components such as hoses, clamps, and the radiator cap condition during replacement.
