Question about 1996 Subaru Legacy
You don't have too, but not bad idea, the timing belt drives the water pump, if you just replace timing belt, and not water pump, water pump could go out and mess up the timing belt, now it has to be done all over again, timing belt, water pump and labor.

As every car is a little bit different, it is impossible to detail
the requirements for every car. However, here is a general guide as to
what you can expect to have to do when replacing a timing belt. I
highly recommend buying the appropriate Hayne's Manual for you car at
an auto supply store. It's a great reference that includes step by step
instructions and helpful pictures.
Wait overnight for the engine to cool off. It's not worth it to risk burning yourself on the engine, which stays hot for a long time!
Disconnect the battery and chock the wheels so that the car cannot roll.
Remove all obstructions to the timing belt cover: This can take a while, as there are usually quite a few things in the way. Here's a list of a few common pieces you'll have to remove:
Remove the air intake assembly.
Loosen the pulley that powers the water pump, if necessary. Some cars require your to remove other equipment such as the power steering pump. If so, remove the belt from the pulley, and unbolt the pump. Move it back out of the way.
Remove any other accessories that interfere with access to the timing belt.
Use a large wrench on the crankshaft pulley to align the mark on the crankshaft pulley with the 0 on the timing scale molded into the engine block.
Remove the timing belt cover bolts and pull the cover off.
Check the tensioner bearings. Replace them if they are loose or noisy.
Check the camshaft and crankshaft seals. If they leak, it could cause premature failure of the new timing belt. Replace them if necessary.
Make sure that all timing marks are properly aligned, then loosen the timing belt tensioner and remove the timing belt. Do not allow either the camshaft or crankshaft to move while the belt is off.
Put the new belt in place. Adjust the tension, if necessary. Make sure that it sits well over the teeth of the timing sprockets. Don't over-tighten.
Apply a new gasket to the timing belt cover and replace it.
Reinstall all of the accessory pumps that you took off earlier, including the water pump. Many mechanics recommend replacing the water pump while you have it off. It's up to you.
Check that all timing marks are still properly aligned.
Reinstall the air intake assembly.
Reconnect the battery.
Start the engine and listen carefully to how it runs. You shouldn't hear any loud knocks if the timing is still correct.

I think you should better go to a mechanic. You'll be charged something like a 100$. If you are not 100% confident in what you're doing, you can damage the car and then it will only get worse. I advise you to go to a mechanic (a guy with his own garage, don't go to walmart or something of the sort, they will charge you 10x more) and ask him how much for the labour and parts.
Good luck !

I would go to auto zone and get a diagram and the timing belt and do it yourself and the water pump (no it does not have to be changed everytime the timing belt is changed but if the car has over 60,000miles then it is best to change them both) it is not that hard especially if the car is not out of time just make sure you disconnect the negative side of the battery

SOURCE: water leak from water pump
No the timing belt does not have to be changed but you do have to remove it to get to the water pump so i would recommend that you do so and also replace the tensioner, i can't tell you a price because i don't where you are i am South Carolina and the parts alone for t-belt ,water pump and tensioner are about 150.00$ cost from Ford (list is a bit higher) and about 3.5 to 4.0 hrs labor at a shop

Get a proper manual like Haynes (amazon, parts store, Haynes.com). You should not have to take either main pullel or cam pulley off to change timeing belt, you DO want a new tensioner and and new idler pulley (if there is one). Failure to replace these may result in a later failure that wipes out the blet, and possibly the motor (if it is an interference motor).
If you can change the oil pump from working on the front side of the motor, you are either a magician or a contortionist;!) and I need you to help me work on my car;~) It's pretty rare for an oil pump to go bad before 400K km or 300K miles ... the bloddy things are in a constant bath of oil!

It is a 2.0L (the delta blocks weren't in tibs until '03). You have to remove the timing belt tensioner, and then you can remove the bolts for the water pump. I would strongly recommend not only taking careful precaution not to disturb the orientation of the gears in this process, but also to replace the timing belt and water pump at the same time. You don't want to go through this process all over again do you?
