Thermostats are cone shaped on top and cylinder shaped with a spring on the bottom. Make sure the cylinder/spring goes into the block. The cylinder/spring portion is the temp sensor.When it reaches the correct temp, it opens up by pulling down on the cone shape and allowing hot fluid from the block to pour into the radiator, at the same time, it pushes the cool fluid from the radiator into the block thru the lower radiator hose. If you had it reversed, you may end up with more problems than you want. Possible blown head gasket, cracked block
