The worst part to replace it is to get the nut loose that holds the clutch to the waterpump pulley.
I recommend removing the fan shroud to gain access. Here is my trick. Do not take off the belt. Wedge a couple screwdrives under the pulley between the pulley and the water pump to help prevent the pulley from turning. Next, get a large cressent wrench and fit it tightly on the nut (fan clutch). Take a dead blow hammar and smack the cressent wrench counter clockwise. It usually takes about 5 or 6 hits, but then the nut will come loose.
They make tools to do this, but I have yet to find one that works.
Let me know if this helps or if you have other questions.
