My water pump had to be replaced and I want to know the steps in how to replace it and why the timing belt had also needed to be repaced?
Do you
have the same problem?

The water pump is driven by the timing belt. That is why it needs removed.

As far as directions, I need to know exactly what size engine is in the car. There were several options, and this is an involved project.

Here are the directions for the 2.5L V6. It is the most common.

2.5L Engine

This procedure requires removing the timing belt and auto-tensioner. Set the engine at Top Dead Center (TDC) on the No. 1 cylinder compression stroke. This should align all timing marks on the crankshaft sprocket and both camshaft sprockets.

1. Before servicing the vehicle, refer to the Precautions section.
2. Disconnect battery negative cable from remote negative terminal on shock tower and properly isolate to prevent accidental reconnection.

CAUTION
This operation must only be performed on a cold engine.

3. Drain the engine coolant.
4. Remove or disconnect the following:

Negative battery cable
Accessory drive belts and crankshaft damper
Support the engine and remove the right engine mount
Timing belt covers
Timing belt and tensioner
Water pump mounting bolts
Water pump

To install:

1. Thoroughly clean all sealing surfaces. Inspect the pump for damage or cracks, signs of coolant leakage at the vent and excessive looseness or rough turning bearing. Any problems require a new pump.
2. Install or connect the following:

WARNING
Wet the O-ring with water to make installation easier; DO NOT use oil or grease.

NOTE
Fit the pump inlet opening over the water pipe and press the assembly together to force the pipe into the water pump.

New water inlet pipe O-ring.

New water pump gasket

Water pump and torque the pump-to-engine bolts to 20 ft. Lbs. (27 Nm)
Timing belt and timing belt tensioner. Set the timing belt tension.
Timing belt covers
Right engine mount. Remove the floor jack and engine block from underneath the engine.
Crankshaft damper
Accessory drive belts and adjust tension
Negative battery cable

3. Fill and bleed the engine cooling system.
4. Start the engine and verify proper operation.

The water pump bolts directly to the engine block using a gasket for pump-to-block sealing. The pump is serviced as a unit. The 2.5L engine uses metal piping beyond the lower radiator hose to route coolant to the suction side of the water pump, located in the -V- of the cylinder banks. These pipes also have connections for thermostat bypass and heater return coolant hoses. The pipes use O-rings for sealing.

The water pump is driven by the timing belt which must be removed to service the water pump. Timing belt covers must be removed to access the timing belt.

1. Before servicing the vehicle, refer to the Precautions section.
2. Disconnect the negative battery cable from the left shock tower.

NOTE
The ground cable is equipped with an insulator grommet which should be placed on the stud to prevent the negative battery cable from accidentally grounding.

3. Drain the cooling system.

NOTE
This procedure requires removing the engine timing belt and the auto-tensioner. To help assure proper alignment at assembly, it may be helpful to set the engine at Top Dead Center (TDC) on No. 1 compression stroke. This should align all timing marks on the crankshaft sprocket and both camshaft sprockets.

4. Remove or disconnect the following:

Accessory drive belts
Crankshaft damper
Right engine mount by safely supporting the engine
Timing belt covers, in this order: upper left, upper right and lower covers
Timing belt and tensioner
Water pump by separating it from the water inlet pipe

1. Thoroughly clean all sealing surfaces. Inspect the pump for damage or cracks, signs of coolant leakage at the vent and excessive looseness or rough turning bearing. Any problems require a new pump.
2. Install or connect the following:

New O-ring on the water inlet pipe by wetting it with water
New gasket on the water pump
Water pump. Torque the bolts to 20 ft. Lbs. (27 Nm)
Timing belt and timing belt tensioner by adjusting tension
Timing belt covers
Right engine mount
Crankshaft damper
Accessory drive belts by adjusting tension
Negative battery cable

3. Refill and bleed the cooling system.
4. Start the engine and verify proper operation.
