make sure the engine is cold , drain the coolant from the rad ,there will be a drain tap/bolt on the bottom of the rad ,be sure to us a container to collect the fluid as should'nt be left to run down a drain etc as is very toxic,disconnect the top and bottom hoses, there are usually two bolts either side of rad loosen these, rad may lift out if not remove the bolts and lift the rad away and out of vehicle , if the cooling fan is attached to the rad remove , will be obvious what bolts need undoing, replace this fan unit on new rad ,then refit new rad , reverse of removal , dont for get to check the drain plug is closed on the new rad , refill cooling system by adding coolant to the expansion tank, run the engine and bleed the air from system ,there will be bleed screws at various points around cooling hoses etc , allow engine to cool 1 hour min ,check coolant level top up and repeat bleeding process as neseccary good luck very straight forward job , keep me posted
