First remove the battery then you should be able to spot the belt tensioner. It will be the smaller pulley that is attached to the engine by an aluminum arm. There is a square hole cut in the aluminum arm that you can simply stick a 1/2 ratchet in. Then push the ratchet towards the car and this will release the pressure on the belt. Be careful not to let the tensioner snap back it could damage it or bust your knuckles. Proceed remove the old belt and follow the belt routing diagram that should be located on a panel under the hood somewhere. Route the belt around everything except for the Power Steering pump. Now push the tensioner again and pull the belt over the power steering pump and slowly let the tensioner back and your done.
Added note - When you replace a belt always check the belt tensioner for proper pressure. This can be done using a torqure wrench set it to 110 ft/lbs for this vehicle. Failure to check the belt tensioner can result in excessive wear on the belt and premature breaking. A good rule of thumb is to replace the belt tensioner the same time you replace the belt.

On the Northstar engine, the water pump is on the RIGHT side of the engine (looking at it from the front. If you look from the left (Drivers) side fender, it's right in front of you- You'll see the water pump drive belt running off the forward camshaft.
The 2000 General Motors/Cadillac Deville came equipped in the 4.6L Northstar engine. Removing the main belt will require depressing the tensioner to free it. The new belt can then be routed across the accessory drive pulleys. The OE AC Delco belts for this application are 6K815 and 3K243.
There is usually a placard under the hood with a diagram.

Cadillacs and the northstar engine are notorious for squeaky belts. if i were you i would not do it yourself. take it to a dealer mechanic.
Yes, change it at 120,000 miles. This is an interference engine. If the belt breaks there will be engine damage.
Best way is to remove the water pump belt tensioner. to get the old belt off and the new belt on. this is the easiest way to accomplish the task. 2 bolts hold it in place on the water pump housing.
