how car ac thermostat works
When the engine is cold no coolant flows through the engine. In order for the system to work the coolant needs to move throughout the system.

When needed the thermostat will work to regulate the engine cooling process.
. 24 Votes Actually most cars do not have thermostats inside the cabin to turn off the AC compressor. Allow your engine to run for a few minutes before inspecting your water pump. At the same time it keeps your car warm it also keeps the engine cool.
If the engine is hot the thermostat opens up and allows the coolant to move. If your thermostat sticks closed and the engine begins to overheat your cars computer may well shut the AC compressor down in a last-ditch effort to reduce the thermal load on the system. The thermostat will then open at a temperature of 850-900 degrees Celsius to give way to the cooling water to carry out the engine cooling process that passes through the radiator.
The thermostat in most cars is about 2 inches 5 cm in diameter. Once the engine has reached operating temperature the thermostat on. The engine will need to run for several minutes to build up heat.
The car thermostat is meant to keep your car warm and cool. The water pump uses power from the crankshaft and serpentine belt to force coolant into the engine and through the rest of the cooling system. A car has an engine that creates a lot of heat that has to be gotten rid of and at the same time regulated so that the engine will perform efficiently and cause the least amount of air pollution.

Its the job of the thermostat to read the temperature of the engine and determine if the coolant needs to flow or not. Newer luxury cars have thermostats -- you select a temperature and the control system does the rest -- but most cars simply run the AC compressor the entire time the AC button is activated. If you thought adjusting your thermostat temperature to 75 degrees meant you would have 75-degree air coming out of your vent it does not.
Once the engine reaches its operating temperature generally about 200 degrees F 95 degrees C the thermostat opens. Of course if your cars engine overheats by that much then odds are that youve got bigger problems than liquefied Butter Pecan. If the car thermostat fails to do this then the car can overheat and your mileage can be affected.
Changing Your Thermostat Temperature Determines How Long Your AC Runs. The thermostat in this car works properly. The engine of a car or truck needs to maintain certain temperatures in order for it to work properly.
First and foremost your cars engine need to run to warm up the engines antifreeze The antifreeze is what carries heat from the engine into the passenger compartment. Its job is to block the flow of coolant to the radiator until the engine has warmed up. One of the main components in charge of regulating how hot or cold it gets is the thermostat.
Its either allowing or blocking coolant from flowing from the motor into the vehicles radiator.

At about 204F 96C the radiator fan comes on and the temperature drops a few degrees.
Simply put it responds to temperature changes in the engine coolant. If it is cold the thermostat stays closed keeping it in the engine. This powers 5-10 pistons depending on the design.
Simply put the thermostat acts as a switch in the cars cooling system. A car engine works much the same way averaging between 195-220F. To accomplish this the car has to have a cooling system that will not only get rid of the heat but maintain a reasonably constant temperature.
They suck in low-pressure low-temperature gas and compress it into high-pressure high-temperature gas. An AC compressor runs off a pulley thats attached via a belt to the crankshaft of your engine. How does a car thermostat work.
The car thermostat operates as a gatekeeper. As the thermostat opens and coolant starts flowing through the radiator the temperature of the lower radiator rises quickly close to the temperature of the upper hose. Changing the temperature of your AC thermostat simply determines if the run-cycle will be longer or shorter based on the current.
