If your timing belt failed, your engine would have died and could not be restarted. On many engines, if you have to replace the water pump, the timing belt has to be removed first. If this is the case with the 2.0 liter engine, then it may be wise to replace the waterpump along with the timing belt. If the water pump fails later, you'll have to remove the timing belt (and probably have to replace it). That happened to my BWM...replaced the timing belt at 60,000 miles and the waterpump failed 500 miles later, making me replacing the timing belt AGAIN.
