Coolant Level Sensor: Symptoms of a Bad or failing Coolant Level Sensor

For the essential and optimal performance of an engine, a coolant temperature sensor is very important. The engine coolant  level sensor work is to take care of the coolant temperature of the engine control module. It is found in the coolant reservoir or radiator. The following are the symptoms of a bad or failing coolant level system;

Engine Overheating

When your engine is overheating, then there is a high possibility that you have a problem with your coolant level system. Your engine overheating can be caused by lots of other factors. However, if the main cause is a coolant level sensor, there is a high possibility that the system is a failing.

Coolant Light Stays On

Having your coolant level sensor light staying on is one of the first symptoms that there is a problem. When the sensor shorts, the coolant level sensor light will likely stay on.

This is an issue because a coolant light that is permanently on will not show you the problem when it arises. This needs to be checked as soon as it shows.

Low Coolant

If the coolant level drops low and you are not alerted by the light then the coolant level sensor or wiring has a problem. The sensor’s work is to make sure that low coolant is detected early. Therefore, if the level in the reservoir dips and the light does not show then it’s an indication that you have an issue with the sensor or wiring.

Poor Mileage

A faulty sensor can send the wrong information to your vehicle’s system thus resulting to an incorrect air-fuel mixture. The end result is the fuel economy dropping and the engine performance dropping.

Black Smoke from the Exhaust Pipe

When the engine temperature is inconsistent, the ECU may add the fuel mixture up to a point where combustion becomes difficult. The excess burning of fuel will lead to a thick black smoke.

These are just but some of the main Symptoms of a Bad or failing Coolant Level Sensor. Therefore, the earlier you take your car to the specialist the better.
