On 2018 and later models, the refrigerant needs to be discharged and recovered before proceeding with the removal of the radiator. To start the removal process, drain the cooling system and remove the air cleaner assembly, intake duct, and coolant reservoir. Disconnect the upper radiator hose, heater outlet hose (if equipped), vent pipe hose (if equipped), and lower radiator hose from the radiator. Carefully disconnect the transmission cooler lines and engine oil cooler lines (if applicable) from the radiator. Remove the upper and lower fan shrouds. On 2018 and later models, remove the grille and left headlight housing, then disconnect the air conditioning refrigerant line from the condenser and plug and cap the fittings. Finally, remove the radiator from the engine compartment. Prior to installing the radiator, make sure to replace any damaged radiator hoses and hose clamps. The installation process is the reverse of removal, ensuring that the radiator is properly seated in the lower rubber mounts and the cooler lines are securely connected with the retaining clips and plastic collars. After installation, refill the cooling system and check the engine oil and automatic transmission fluid levels. On 2018 and later models, it is recommended to have the system evacuated, recharged, and leak tested by a professional shop that discharged the refrigerant.

The cooling system should be refilled and the engine oil and automatic transmission fluid levels should be checked.
