The dealer is changing my water pump whih is leakng and covered under warranty. They called and the lady said my drive belt is cracked. I repeated what she said back to her and she said yes your serpentine belt. I thought we had a timing chain? Or are these parts two different things?

A timing belt, which the car doesn't have, controls timing of an engines valves
A serpentine belt drives mechanical engine accessories (which ones depend on the car since some cars have electric ones instead of belt driven ones, but it's often things like the alternator and AC compressor.
the good news is on most cars a timing belt replacement is like a couple hundred in parts that takes $500-$1000 in labor to replace.
A serp. belt is usually a $20 part you can replace in a few minutes with a socket or wrench.

I could see $120 if you were only doing the belt, as they're likely charging 30-60 minutes of labor (despite it only taking 5)....but in that case I'd say buy one online for 20-30 bucks and do it yourself.
But the belt is already off to do the work they are doing, the only "labor" is the exact same reinstall of the belt they'd do for free if you didn't buy a new belt.

To echo what Kurtz said, they shouldn't charge you labor for installing the belt. The serpentine belt runs the water pump, so when you replace the water pump that belt has to come off anyways. They would have to install a belt, new or not, as they re-install the water pump. That belt shouldn't be more than 20 bucks online.
