The second clamp/bracket is located to the right side of the radiator.
The hoses are shown from another angle. Note that from the factory the hoses are held in place with the spring clamps you can see. You may find yours has the common jubillee clamps if someone has already done some work on the cooling system of your vehicle.
Okay so lets get down to removing the radiator. Firstly you need to slide off the power stearing reservoir from its bracket. Using a flat blade screwsdriver or similar tool gently move the bracket locking tab forward whilst pulling gently upwards on the reservoir. When the reservoir comes free place it aside out of your way.
If you look under the vehicle, behind the front wheels and to the center of the underside you will see a drain valve as in the following picture. Simply open the drain valve by turning it until coolant runs out – make sure you have a suitable container beneath to catch the coolant.
