In this video, young mechanic Aiman will show you how to test your car/truck engine thermostat in minutes to see if it is working properly or not such as stuck or faulty. The test should be valid for all auto vehicle thermostats regardless of type, year, model or make since they all worked on the same principle.
The method involved taking the thermostat out of the vehicle being repaired or checked on and putting the thermostat in a boiling water. If the thermostat is not faulty then it should open after reaching a certain temperature usually near the boiling point.
This test was being done on a thermostat for a 2003 Honda Accord (same gen as 2004, 2005, 2006 & 2007 DX, LX & EX 2.4L or 3.0V6). All hondas such as Civic, CRV, Element, Pilot & Odyssey have the same thermostat design.
The thermostat in your car is responsible for regulating the flow of coolant for your vehicle’s engine. It responds to temperature changes, by a small open or closed valve. For example, when you start your car in the morning, the thermostat is in a closed position. Your car thermostat is designed to open up once your car’s engine reaches its full operating temperature; allowing coolant to flow into the radiator. This helps prevent the engine from overheating. When you have a faulty thermostat it can damage your engine and other mechanisms of the cooling system won’t be able to do their job. To make sure your car thermostat is in working condition, it’s important to check it. Follow the steps below, to learn how to check your car thermostat.
How to check your car thermostat while being installed in the car and without having to take it apart:
Have your car on level ground and make sure the engine and radiator are cool.
Open the car hood and find the thermostat. You can do this by following the upper radiator hose towards the engine. The end of this hose will be attached to the thermostat housing. With most cars, you should be able to find your thermostat in the housing. There are some vehicles where the thermostat housing will be attached to the lower radiator hose. If you need additional guidance locating your thermostat, review your vehicle service manual.
Next, you will need to test your car thermostat. You can do this by removing the radiator cap on your car to check the coolant flow. Start your car’s engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open.
If you find the coolant is flowing, it means the thermostat valve is open. This is usually a good indicator of if you need to replace your car thermostat.
If you notice the coolant is not flowing, wait until your car’s engine has reached the operating temperature. Have another look through the radiator filler neck to see if the coolant has begun to flow. If you still don’t see the coolant flowing and your car’s temperature gauge starts to rise, this means your car’s thermostat is in a closed position.
What are the symptoms of a bad thermostat?
Symptoms of a Bad or Failing Thermostat. Common signs include the temperature gauge reading being very high or changing erratically, engine overheating, and coolant leaks. A car thermostat regulates the flow of coolant through the engine and is an incredibly important player in the operation of your vehicle's engine.
What happens when thermostat goes bad i.e. get stuck closed?
A bad thermostat can cause the car to swelter, as the thermostat is a heat-sensitive control device situated at the radiator hose. ... If the thermostat is stuck closed, antifreeze won't flow from the radiator, resulting in the car overheating. Thus, if this happens, one of the possible causes is a broken thermostat.
