Moving to the front of the vehicle and the bottom of the radiator you will find there are two hoses connected to two metal elbows. These carry transmission fluid from the auto gearbox to the transmission cooler that is fitted into the bottom of the radiator. They have to be removed. Before you do so its best to have something at hand to plug and block the hose ends, or you will have transmission fluid pouring out over the floor. Some find ‘AA’ batteries are a perfect fit, just don’t push them all the way in the hose or you will find it hard to get them out!
You can now drain the radiator using the drain tap located in the bottom right of the radiator when viewed from the rear. It is labelled in the image above. Simply open the valve by turning it and collect the coolant in a suitable container as it pours out the small ‘L’ shaped hose shown. While the radiator is draining loosen the two bolts that hold the plastic fan shroud to the radiator, lift up slightly to disconnect the lower lugs and push the shroud back over the viscous fan so it clears the radiator.
