the side with the spring goes inside the motor

the same way you replace it on any car you buy a chilton manual for your car and a thermostat and then follow the instuctions in the manual
yes one way
ok
Spring towards engine.
No
the thermostat is a water/coolant flow regulator using pressure or heat from the water/coolant to open itself and let water circulate. when the thermostat gets stuck (won't open/close normally), the car's engine will overheat, usually will get replaced (if you go to a certified mechanic) or will be removed and not replaced (if you go to an uncertified McGiber type mechanic), although this does not affect your car in a negative way.
We are unable to post pictures on this site. Your best bet is to go to your local library and check out a Chilton's car manual ... it should have pictures as well as a good descriptive of the thermostat changout.
is car thermostat necessary in a tropicalize car?
