It's not difficult, about 20 min. ,a flashlight, and a torx screwdriver are all that's required. Take out the glovebox, take off the r&l panels under the dash (watch out for the yellow wire on the right panel as that is for the airbag), take out all the torx screws around the glovebox. Remove the torx screws under the dashtrim pad that goes all the way across the panel that surrounds the radio, and carefully (because the panel is actually made of a very light weight plastic covered with vinyl) just pull the panel loose (I think it's easier starting on the drivers side). This gets you to the radio which is held in position by torx screws, take out the screws and the radio just slides out. Just be careful with all the plastic as it breaks very easily, same with all the little tabs around the panel.

The thermostat on a 1997 Oldsmobile Achieva SL goes on the very bottom of the water pump. It is inside the top hose of the radiator on the end that attaches to the water pump.
