Found this for 2.7L engine.

if you haven't bought the belt yet, go to auto parts store (autozone), they'll probably offer you the correct size & the diagram.

You will be assisted by the layout engine water hoses?

If there is currently a belt on the car, draw a diagram.

It is often not too hard to figure out haw the belt goes, since one side is grooved, and the other is flat. Because of that, the pulleys are either grooved or flat surfaced.

We are talking about the Timing Belt and not the Drive/Surpentine Belt?

For the 1999 Mercury Mystique Water Pump Belt on 2.5L V6 Engine:

Probable Causes: Belt: worn out, started slipping. Overheating caused by failure of Belt. Lost antifreeze: caused by failure of belt, not turning Water Pump Pulley, not circulating anitfreeze, which resulted in overheating.
