Q: Does the 2005 Dodge Stratus SXT 2.4L water pump run on a timing belt or drive belt?

I have a 2005 dodge status sxt with a 4.2L engine. I was driving to work and the alternator belt disintegrated though at the time I did not know that was the cause of the shudder. Electrical light came on and lights grew gradually dimmer. I drove for about 20 minutes to my destination with no other ill effects. Though I barely made it. After examination and seeing the belt was gone, I tested the drivability by driving it 5 minutes further. Now the battery is dead and the a/c doesn't work, of course, but I was wondering how the water pump is driven on this engine? I made it 25 minutes with just the symptoms of no a/c and a dying battery but it was cool (50's) in stop and go traffic. I want to try to make it about 5 miles to the repair shop. What do you think?

My car has 110000 miles.
My car has an automatic transmission.
