I need to replace the water pump?

Hello,

In order to replace the water pump you will first have to remove the serpentine belt.
The water pump is behind the water pump pulley, it is a smooth pulley mounted with 4 bolts.
Remove those bolts to take the pulley off. Then you will have access to the water pump mounting bolts. Simply remove those bolts to take out the water pump.
Before getting started be sure the drain the coolant to reduce coolant spilling all over the engine bay.
