I'm surprised the previous owner did not replace hoses & belts when they did the water pump. The serpentine belt on ANY car should be replaced every 30,000 miles. It just does too much to trust it much further. It's tough with a used car to find out what was done already and when, & what still might need to be done. It takes effort to reach a comfort level where you think you have a handle on the car's condition. This website really helps determining the actual service life of parts vs the OEM specs.
