What Does a Car Thermostat Do?
As any other water-cooled engine on a passenger vehicle, the engine in your car operates at a temperature range of approximately 195–220 °F (91–104 ºC). To help it operate within this range, your car engine uses a thermostat.
In simple terms, the thermostat responds to changes in temperature—in this case, coolant temperature—by opening or closing a valve to control coolant flow between the radiator and engine. The valve itself operates through a wax-container element. Thus, the thermostat is small, simple and effective. The expanding element container in the thermostat faces and contacts the engine coolant. As the coolant temperature rises, the fluid (or wax) in the container begins to melt and expand, pushing a small rod that separates a center plate from its surrounding mounting base to open the valve.
The Thermostat at Work
The thermostat starts at a closed position when you start the engine to help it reach operating temperature. As coolant temperature rises, it begins to open. The opening allows hot coolant in the engine to flow into the radiator, while the water pump pushes lower-temperature coolant from the radiator into the engine. When the lower-temperature coolant reaches the thermostat container, the expanding fluid begins to contract, closing the thermostat's valve.
During engine operation, though, the thermostat actually never fully closes or opens, but gradually nears either state to control coolant flow, depending on engine operating conditions. This allow the engine to operate at the best temperature. This ideal engine-operating temperature accomplishes several goals: It helps engine oil to lubricate efficiently and to remove harmful deposits. It reduces emissions and gas consumption, and contributes to engine performance. Thus, the thermostat has an impact on your engine's health and longevity.
Symptoms of a Bad Car Thermostat
A failed thermostat will prevent the engine from operating within its ideal temperature range and affect its performance. For example:
· A thermostat stuck opened will cause a continuous flow of coolant, resulting in a lower operating temperature. Since the oil operates below temperature, the condition accelerates parts' wear, reducing engine efficiency and increasing emissions over time.
· On the other hand, a thermostat stuck in the closed position will prevent coolant flow and cause the temperature to steadily rise. If you fail to notice and keep your engine running, in a matter of minutes your engine self-destructs. Literally.
Either way, your engine will suffer damage. The difference is just in the amount of time it takes. Still, a failing thermostat is not the only cause for an abnormal engine operating temperature.
Other reasons include low coolant level, a bad water pump, a worn out or loose water pump belt, cooling system leaks, a clogged radiator, a failed radiator fan and a collapsed radiator hose. Whatever the cause, it's a good idea to start looking into the problem before it's too late.
Common Causes of Abnormal Engine Temperatures
· Bad thermostat
· Low coolant level
· Bad water pump
· Worn-out water pump belt
· Loose water pump belt
· Cooling system leaks
· Clogged radiator
· Bad radiator fan
· Collapsed radiator hose
How to Test a Car Thermostat
Checking your car thermostat is the best way to know if the unit has actually failed. The testing procedure requires a kitchen thermostat and a pair of needle nose pliers. First, you need to remove the thermostat from your car.
The thermostat housing is accessible in most cars, but you still need to follow some precautions that might apply to your particular model. If you need more help, the best way is to follow the instructions in the repair manual for your particular vehicle make and model.
Once you have removed the thermostat from your car:
1. Visually inspect the thermostat. It should be in the closed position. If it is opened, replace it.
2. Place a kitchen pot on a stove. Pour enough water into the pot to cover the thermostat.
3. Submerge the thermostat in the kitchen pot, but don't let it touch the bottom of the pot. Use a pair of needle nose pliers for this.
4. Start heating the water and place the kitchen thermostat in the pot, but don't allow the thermostat to touch the pot. You just want to monitor the water's temperature.
5. Watch closely and notice at what temperature the thermostat begins to open.
6. Make a note of the temperature at which your thermostat began to open.
7. Wait for the thermostat to open completely and make a note of the temperature. Then, remove the thermostat from the pot and check that the thermostat gradually closes completely.
8. Compare your notes to the thermostat operating temperature specifications in your vehicle repair manual. If your thermostat deviates from the specifications, or the thermostat mechanical action deviates from the one described above, replace it.
Most vehicle engines operate at a temperature range of approximately 195–220 ºF (91–104 ºC). Check your vehicle repair manual for the thermostat operating range, and make sure you have the correct one for your application. Or replace it, if necessary.
