How to remove and reinstall Radiator and Coolant Reservoir in a Nissan Frontier?

Detach the hose from the reservoir, remove the reservoir retaining bolts and lift the reservoir straight up. Pour the coolant into a container, wash the reservoir and inspect for cracks. Disconnect the battery cable, set the parking brake and block the rear wheels. Drain the cooling system, disconnect the transmission cooler lines and loosen the hose clamps. Unbolt the small brackets, carefully lift out the radiator and inspect for leaks. Spray with a garden hose nozzle, check the radiator mounts and guide the radiator into the mounts. Refill and bleed the cooling system, start the engine and check for leaks. Allow the engine to reach normal operating temperature, cool completely and recheck the coolant level. Add automatic transmission fluid if needed.
