How do I get to the water pump, driver's side? on 1996 Cadillac Seville SLS

Want to change the water pump belt, 96 SLS. Didn't know it had one. Where is it?

the front cam in the rear of the motor drives the water pump. it is down there. taking out the battery and tray helps with the acess. we replace the gear on the cam, belt, tensioner and pump as an assembly.
