I've found the Haynes Repair Manual that you can get at Auto Zone to be the best one there is. They have step by step instructions with pictures on repairing or replacing just about anything on your auto. You can get them for around $20 - 25. Is yours a 3 or 4 cylinder? Auto Zone has a new service where you can actually look up repair instructions for your vehicle with pictures. Here's the instructions for a 3 cylinder for your year, make and model:

1. Disconnect the negative battery cable.
2. Drain the cooling system.

CAUTIONWhen draining the coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

1. Remove the air cleaner assembly.
2. Loosen but do not remove the four coolant pump pulley bolts.
3. Raise and support the vehicle safely.
4. Remove the lower splash shield.
5. Remove the air conditioner compressor drive belt.
6. Remove the lower alternator cover plate bolts, loosen the alternator adjusting bolt and remove the drive belt.
7. Remove the crankshaft pulley.

9. Remove the timing belt.
10. Remove the oil level dipstick and guide tube.
11. Remove the alternator adjusting bracket from the water pump.

13. Remove the water pump mounting bolts and nuts. Remove the water pump from the vehicle.
