So, is your car giving you headache because of constant overheating? Engine operating temperature remains below normal? Here is all you need to know about car thermostat and problems associated with it!-Brought to you by PartsAvatar Car Cooling Parts online.

 If you are worrying about car thermostat problems and engine’s overheating issues then no need to anymore because PartsAvatar Performance car engine parts presents a detailed guide on car thermostat and problems associated with it!

Car thermostat

Do you know who controls coolant flow in the engine? Well, its the job of car thermostat to regulate the flow of coolant through the engine. Temperature is very pivotal in engine operations.

Increasing or decreasing engine temperature can create havoc for your car. When the engine is started, after reaching a certain operating temperature, the thermostat activates which eventually causes the coolant to start doing its job of getting re circulated between radiator and car engine.

The constant flow of coolant in the engine is pivotal for engine’s functioning at a certain operative temperature. It is very important to maintain accurate engine temperature for correct performance. So, it’s the job of thermostat to do so by opening and closing at right time.

If by any chance, car thermostat stuck in between its operation, then the whole flow of coolant stuck and it won’t be able to flow to and fro the engine and the radiator which will lead to hot temperature of engine and eventually overheating. The expanding element container in the thermostat faces and contacts the engine coolant. As the coolant temperature increases, the fluid in that container begins to melt and it pushes a small rod to open the valve of thermostat.

While the engine is running or operating, the thermostat never fully closes or opens, but it is near either state to control the coolant flow depending on the conditions provided by the engine.

Thermostats are not only helpful in maintaining accurate engine temperature but also they help in various other operations just by controlling the engine temperature.

The engine temperature that is appropriate, helps the oil lubricate the engine, removes residues or deposits, improves gas consumption and optimizes the engine’s performance. So, maintaining the thermostat can hugely impact your car’s engine health.

Replacing car Thermostats can ensure you great fuel economy, reduce engine wear and improve cold weather durability.

Symptoms of Malfunctioning Thermostats

Here we have listed some important symptoms of car thermostat malfunctioning that you should keep an eye on. Maintaining thermostats is very important because delaying so could result in heavy engine parts repair and huge budget disturbance.

If the automotive thermostat’s sensors fail to properly open the valve, it will allow the coolant to flow continuously, which won’t help the car engine to gain relevant temperature for its operation. The temperature often lowers in such situation which hampers the oil operation and ultimately causes premature wear of auto parts. In such case, you must get your car’s thermostat checked by a professional mechanic and get the damage repaired as suggested.

Overheating is the most common symptom that might suggest that the time has come to change car’s thermostat. If the thermostat’s valve is stuck closed, the coolant wont flow freely from the radiator resulting in engine working under heavy temperature and ultimately overheating of engine can be observed.

Though there are various other car parts damages that contribute to engine overheating so it is suggested to seek professional advice in such instance!

Engine needs to perform under certain temperature which should be neither too hot nor too cold. For the engine to work under proper accurate temperature conditions it is very important for the coolant to flow without hindrance. But only bad or malfunctioning thermostat would cause problem which would result in inaccurate temperature for car’s engine for its operation. Car engine is quite expensive part and needs lots of labour because of its complex structure, so you might end paying a lot of dollars in its repair! You can make a choice.

Are you by any chance noticing poor fuel economy? This could be also due to engine’s poor performance and the credit for this might also go to the bad thermostats.

Bad engine performance impacts fuel economy drastically so better have this fixed before you have to spend your hard earned cash.

Leaking coolant is also an evident condition which can be caused when appropriate coolant is not allowed to flow by malfunctioning thermostat. Where will you find the leak? The most common place to find the leak is thermostat housing! So, get the leak fixed and get the thermostat replaced too, if needed.

Replacing Car Thermostat

It is very easy to replace car’s thermostat. There are various illustrative videos and instructions on internet. Here we explain it all in very simple way. You can try it as a DIY if you are pretty sure about your skill, but if you can’t then don’t worry because you can always take assistance!

Park your car on a safe place and put it on a level ground. Make sure that the engine has cooled down so as to drain down the cooling system completely.

Start with removing the radiator hose by twisting it so that it can loosen up from the thermostat housing. Lift the cover and remove the thermostat. Keep the debris from entering the engine by stuffing clean rag into the opening.

Now its time to install the new thermostat that you can buy from any online aftermarket car parts store. Make sure that the thermostat is not placed upside down; the copper heat sensing element should be facing the engine.

You can also do some cleaning job in the mean time like cleaning the rim of thermostat housing, or cleaning the water jacket corrosion etc.

Now remove the old gasket carefully from the housing and put a new gasket in its place and secure it. You can also take your car manual’s help to do so and torque the housing bolts evenly.

Re attach the hoses and pour the coolant back into the car. Now run the engine to reach its operating temperature and check leaks.

Make sure that you take a short trip to make sure that the temperature gauge is staying at normal now. If not, then its advised to take a professional help.
