- Cooling system service on a 2013-2019 Nissan Sentra
Installation Notes and Tips
Verify inlet and outlet orientation before installation: this unit uses a right-side inlet and left-side outlet. Confirm radiator dimensions, hose routing, and mounting points against the original part before assembly. Because the cap is not included, reuse or replace the cap as needed based on the vehicle’s cooling system specification. Always inspect hoses, clamps, and coolant condition when replacing the radiator on a Nissan Sentra.
