Protect car’s engine from overheating by installing Top quality Coolant Temperature Sensors @Partsavatar Auto parts.

Is your car suffering from poor Fuel economy? Engine is overheating? Don’t worry as Partsavatar offers high quality Coolant temperature sensors at affordable rates! ~ Partsavatar Auto Engine parts.

Drivers often have complaints regarding poor fuel economy, smoke emitting tailpipe and overheating engine. We know the root cause is coolant. But how do we know that is the right temperature of coolant?  We can determine coolants temperature with the help of car's coolant temperature sensors. Almost every modern vehicle comes equipped with coolant temperature sensors. So, what are coolant temperature sensors and how do they help us? We will give you the answers in detail.

Engine coolant temperature sensor or commonly called coolant temperature sensor is designed to monitor the temperature of the coolant inside internal combustion engine. The coolant absorbs heat from cylinders which is produced by the engine when it is running.

The coolant sensors detect the change in temperature and send the signal to the computer so that the changes can be made to engine’s timing and fuel calculations for better performance. This is done to tell if the engine is cold, warming up or at normal temperature or in worst situation is overheating.

Temperature plays an important role in determining engine’s performance. Engine performance issues could arise if the coolant temperature sensor goes bad.

How it works?
Car’s coolant temperature sensor is located near the thermostat of a vehicle’s engine so that it can give optimal results. The tip of the sensor is located near the coolant of the engine. The temperature sensor works by measuring the temperature that the thermostat or car’s coolant is giving off. The sensor reads the temperature and sends the signal to the on board computer or ECU which further adjusts engine performance based on this information.

Temperature sensors not only provide information about coolant temperature but they also tell whether or not engine needs a rich fuel mixture, to open exhaust gas recirculation or to limit spark advance during emission.

Coolant sensor Diagnostic fault codes
If the coolant temperature sensor starts malfunctioning, it will prompt the check engine light to turn on and after decoding the trouble code, you will know the root cause of blinking check engine light.

P0115- Engine coolant temperature circuit
P0116- engine coolant temperature circuit performance
P0117- engine coolant temperature circuit low input
P0118- engine coolant temperature circuit high input
P0119- engine coolant temperature circuit intermittent

So, whenever check engine light starts appearing on the dash, it’s better to visit your mechanic or a technician and he will decode the trouble code and tell you the exact cause.
When to Replace a Coolant sensor?
Following are the few symptoms that will alert you of the potential problem with coolant sensor. Because of coolant sensor’s vital role in triggering so many engine operations, a bad sensor will often cause poor fuel economy and emission problems.

Check engine light

We often get scared whenever the “Check engine light “starts appearing on the dash. Though there are various reasons that cause the check engine light to illuminate. But in pretext to failing coolant sensors, check engine light may be giving you an indication of potential problem going on with it.

If it detects any trouble code or problem signal from the coolant temperature sensor, it will start illuminating. Incorrect coolant temperature gauge readings due to faulty coolant sensor on instrument panel may also trigger check engine light.

Check engine light signal won’t disappear until you solve its problem. So annoying!
It’s better to call your technician and he will troubleshoot the problem code that the check engine light is showing. Problem code might be one of the above stated codes. It will eventually notify you of a problematic coolant sensor.

Engine Overheating
Overheating of engine is a crucial problem. There are generally many causes behind the overheating of the engine. But a faulty coolant temperature sensor can also lead to engine overheating.

Coolant temperature sensor will fail completely and will eventually start sending hot signals to the computer. The computer will read the wrong input and will compensate incorrectly for a lean signal which can result in overheating.

Overheating if not addressed can lead to multiple auto parts failure. I think it is economical to replace coolant sensors than under the hood auto parts replacement.

Poor Fuel Economy
Poor fuel economies are often caused due to failing coolant temperature sensor. Corrupt coolant temperature sensor will send false signal to the computer and throw off the fuel and timing calculations. In some cases, faulty coolant sensor can send permanently cold signal to the computer.

Computer will start using more fuel than necessary thinking that the engine is cold based on the signals received. This will damage not only fuel economy but also the engine performance.

Black smoke from Exhaust pipe
Black smoke from vehicle’s exhaust pipe also indicates a faulty coolant temperature sensor. After the faulty coolant sensor sends the faulty cold signal to the computer, the computer thinking the engine to be cold will enrich the fuel mixture further. Too rich fuel won’t be able to burn in the internal combustion chamber and hence as a result the exhaust pipes will start emitting black smoke.

Black colored smoke is an indicator of danger. If ignored it can also damage exhaust system parts and catalytic converter which is very costly to replace. Do not waste any second in calling a mechanic.

DIY- Replacing Coolant Temperature Sensor
It is often advised to replace the coolant temperature sensor when the engine is rebuild or when it goes faulty.
Before installing sensors, allow the engine to cool down first. Make sure to drain out coolant in the cooling system before beginning the replacement process. Do not drain the radiator draining some of the coolant is enough.

Open the valve to drain the antifreeze. Once you finish the draining of coolant, replace the old sensor with new sensor.

 Do refill the radiator with coolant before finishing. Tighten the sensor carefully to prevent damage. Make sure that air is out of cooling system otherwise the engine may start overheating and cooling sensors won’t be able to read correct reading.

Coolant temperature sensors are very important for fuel economy and engine performance. Have your vehicle checked by the technician as soon as you detect any problem.

  1. Car overheating problems are quite common, it's mostly due to continuing the running of engines and lack of proper engine maintenance and also coolant is a crucial fact. Therefore, nowadays, in every vehicle, we have found modern coolant system with coolant temperature sensors. As a vehicle owner, we should follow these kinds of crucial instructions to keep our car in a good condition for a long time period. Thanks for highlighting such important facts about car coolant system.
