How does a car thermostat work?
Any liquid-cooled car engine has a small device called the thermostat that sits between the engine and the radiator. The thermostat in most cars is about 2 inches (5 cm) in diameter. Its job is to block the flow of coolant to the radiator until the engine has warmed up. When the engine is cold, no coolant flows through the engine. Once the engine reaches its operating temperature (generally about 200 degrees F, 95 degrees C), the thermostat opens. By letting the engine warm up as quickly as possible, the thermostat reduces engine wear, deposits and emissions. If you ever have the chance to test one, a thermostat is an amazing thing to watch because what they do seems impossible. You can put one in a pot of boiling water on the stove. As it heats up, its valve opens about an inch, apparently by magic! If you'd like to try this yourself, go to a car parts store and buy one for a couple of bucks. The secret of the thermostat lies in the small cylinder located on the engine-side of the device. This cylinder is filled with a wax that begins to melt at perhaps 180 degrees F (different thermostats open at different temperatures, but 180 F/82 C is a common temperature). A rod connected to the valve presses into this wax. When the wax melts, it expands significantly and pushes the rod out of the cylinder, opening the valve.
How can you tell wheather the radiator or the thermostat is not working because my car has a very serious problem with it overheating?
Can a car go without a thermostat I just removed the thermostat from by Ford explorer car so I just need to know if there are any effects to the engine?
Thermostat can stick open or closed. If sticks open, car will take longer to warm up because coolant is constantly flowing thru engine. If thermostat is stuck closed, engine will eventually overheat. In order for all emission systems to work properly, thermostat needs to be working. For 1995 GEO Prizm, if thermostat is working correctly, car should maintain proper operating temperature after is warmed up. If any doubt about thermostat, changev it every few years…
the location is under the throttle body of the car. when standing at the front of the car locate the upper radiator hose on the right side and follow the hose toward the engine. where it connects to a metal tube. follow that tube and where the tube is bolted to the motor is the thermostat location. this tube holds the thermostat. one thing to know is that replacing the thermostat is very difficult and…
your fan probily isn't turning on when car is overheating check to see if fans are on if not turn on a/c if they turn on you need a electric fan thermostat if not check fuses and relays if it still dosent work replace fan motor if fans work and car over heats replace thermostat a good way to test a thermostat is to slightly rev the engine if heat goes up the thermostat is…
To change the thermostat on a Kia Sorrento you will first need to make sure the car is completely cool since the thermostat is located near the radiator. Once your car is cooled down, simply unbolt the old thermostat and bolt in the new thermostat. It is that simple, there are no other parts to remove.
Most cars will work without a thermostat. The purpose of the thermostat is to allow the engine to warm up more quickly by reducing the flow of coolant to and from the radiator. Because of the excessive cooling, however, your engine will not run at the right temperature under cool conditions and you may have excessive engine wear, reduced fuel efficiency and reduced passenger heat. In an emergency though, it's fine.
What else can you do to your 1991 Honda if it is still overheating by the time you go a mile if you have changed the radatior and the thermostat?
1) ONE THING YOU COULD TRY IS CHANGING THE RADIATOR CAP...IF IT'S BAD THE CAR WILL BOIL OVER AND APPEAR TO BE ALWAYS OVERHEATED WHEN ALL THAT'S REALLY WRONG IS THE LACK OF PROPER BACK PRESSURE DUE TO AN OLD/DEFECTIVE RADIATOR CAP. 2) IF THAT DOESN'T WORK YOU COULD TAKE THE THERMOSTAT OUT AND TRY DRIVING THE CAR WITHOUT IT IN AND SEE IF THE CAR RUNS LONGER BEFORE OVERHEATING...IF IT DOES THEN THE THERMOSTAT…
If your mechanic installed a new thermostat in your car and it did not work so your car overheated and cracked your cylinder head is it his fault and if so how can you prove it?
If the thermostat failed it is not the fault of the mechanic, he didn't build the thermostat he just installed it. If it failed because of improper installation that is another story. But you are also at fault,maybe more so than the mechanic ever hear of a temperature gauge. it doesn't just get to hot all of a sudden that happens with not stopping when it get in the red zone.
First one should go to a mechanic's school, or apprentice with a mechanic. You would have to learn about such things as an engine block, and where the thermostat is located. You would need jacks to get the car up high, and work your way to the thermostat housing, at which point you would disconnect the hose and bolts. This is a very complex question.
