Chances are you placed the thermostat in backwards or there isn't enough coolant in the system to circulate thru the engine. You may have a bad water pump. But first check your temp sending unit. If your temp gauge doesnt go up at all, thent hats the problem, its your temp sending sensor, replace it answer check radiator cap, u may need a new one have been known to buy a bad thermostat when it was new check water pump with engine running above idle, and at running temp. remove radiator cap and look in radiator if water is moving, your pump is good so is thermostat if no movement is thermostat or pump u might also chck to see if air is trapped in cooling system, a lot of new vehicles need system to be bled of air after doing a repair HINT if you have a coolant overflow tank, most vehicles need coolant to be added thru this tank and not thru radiator, this being done to stop overfilling of radiator and excess air from getting in system
On the engine block, near the thermostat housing.
Yes, it controls the coolant flow around the engine block, without coolant the engine would overheat.
When the car is cold the thermostat is closed. When the thermostat is closed the coolant does not circulate or get in to the engine block.
The thermostat in a car regulates the coolant temperature inside the engine. When the engine is cold, the thermostat is closed, allowing the heat from the combustion chamber to heat the fluid (coolant) in the coolant galleys in the engine block. Once the engine reaches an optimal temperature, the thermostat opens, allowing coolant to flow through the radiator. The thermostat then controls the flow of coolant to hold the engine at its optimum operating temperature, irrespective of engine load and operating condtions.

The thermostat is located in a removable housing at the engine end of the upper radiator hose Drain about 1 gallon of coolant from the radiator Remove this housing Note how thermostat is installed Clean both surfaces Replace thermostat and gasket Re-install housing Re-fill coolant slowly to prevent an airlock Start engine and look for leaks Run engine to normal operating temperature with heater on Re-check coolant level
The thermostat is typically mounted on the engine block or in the coolant passage, and it controls the flow of coolant to and from the engine. When the engine is cold, the thermostat remains closed to allow the engine to heat up quickly. Once the engine reaches the desired operating temperature, the thermostat opens, allowing coolant to flow into the engine and maintain optimal temperature. Therefore, the thermostat itself does not move up or down but operates based on temperature changes.
The thermostat is generally found in the engine where the coolant exits the engine block before it gets to the radiator. And yes, a thermostat is necessary for todays engines.
In a 1991 Ford Taurus with a 3.0L engine, the thermostat should be installed with the spring side facing the engine block. This orientation ensures that the thermostat opens properly to allow coolant to flow when the engine reaches the designated temperature. Always make sure to replace the gasket and check for any leaks after installation.
