On 2012 and later models, start by discharging the air conditioning system. Disconnect the negative battery cable and drain the cooling system, saving the coolant if it's in good condition. Remove the air filter housing and loosen the hose clamps to detach the upper radiator hose. If it's stuck, use adjustable pliers to break the seal. Remove the side air deflectors and disconnect the lines to the condenser, plugging them. Disconnect the reservoir hose and remove the coolant reservoir or power steering fluid reservoir, depending on the engine. Remove the bolts attaching the shroud to the radiator and lift the shroud out of the engine compartment. Loosen the clamp and detach the lower radiator hose, using retaining ring pliers if available. If there's an automatic transmission, disconnect the cooler lines and plug them. Remove the radiator mounting bolts and carefully lift out the radiator, being cautious not to spill coolant or scratch the paint. Inspect the radiator for leaks and damage, and have it repaired if necessary. Clean the radiator with compressed air and a soft brush, being careful not to bend the cooling fins. Check the radiator mounts for deterioration and ensure they're clear when reinstalling the radiator. To install, follow the reverse of the removal procedure. Fill the cooling system with the proper mixture of antifreeze and water, check for leaks, and add more coolant if needed. If it's an automatic transmission vehicle, check and add fluid as necessary. Finally, have the air conditioning system evacuated, charged, and leak tested by a professional.
