There should be either an arrow or the word up stamped on the top side. The taller more pointed end is usually the top part.

If your 1997 Ford Taurus won't go into reverse, there may be a problem with your transmission. You can try checking your levels, but you need to take it to a mechanic.
Thermostats install into the housing with the spring-side towards the engine.See "Related Questions" below for more about Taurus / Sable thermostat installs.
I know that the spring goes towards the engine and on the 4.0 L - OHV engine the vent hole in the thermostat is at the top with the vertically mounted thermostat
The way it came out....
The thermostat is located on the right hand side of the Radiator but to the bottom, you have an overflow, bypass and two other hoses that connect to the Thermostat housing. Things to note, only 2 bolts and it is off. The Thermostat can only go in 1 way and the default temp is 195.
need diagram of the sepentine belt and how it go on.
GO TO WWW.AUTOZONE.COM AND LOOK FOR THE SPECS. LINK
I'm going to go way out on a limb here and say 1/2" or 7/16".
yes one way
Follow the upper radiator hose from the radiator to the engine. The upper rad hose is attached to the thermostat housing at the engine. You need to drain some coolant out of the radiator, remove upper hose from thermostat housing, remove the bolts attaching the housing to the engine, remove the housing and remove the thermostat. Take note which way the thermostat comes out, you want the spring end to go inside block.
