What does the oil sight glass look like on your Toyota Corolla?

First of all, it is important to identify this indicator on your Toyota Corolla. It is red in colour and represents a small burette with a drop on the right. Like all red lights, this means that you must stop your Toyota Corolla as soon as possible. To check it works, you will see it turn on when you turn the ignition. If it does not light up, your indicator light is defective.
Do not mix up this light with the almost identical yellow one. This one signifies that you are very likely short of oil.

What is the purpose of the oil indicator light that lights up on your Toyota Corolla?

Now, let us explain to you what it is for and why it is essential. Contrary to what we may think, it has nothing to do with the oil level in your Toyota Corolla. Furthermore, it is there to report a loss of pressure in this engine oil, which can quickly damage or even destroy your Toyota Corolla’s engine. That’s why as soon as it appears on your vehicle, you must stop the car.
then, we will explain to you what this oil is used for in your Toyota Corolla’s engine. It works with a set of metal parts, which are regularly in contact and therefore need replacing. The oil under pressure therefore ensures the lubrication of these parts to stop them from being damaged. Otherwise, it also serves to cool them down since they heat up quickly when you drive your Toyota Corolla. At last, the oil also cleans and circulates dirt that may well affect your engine.
You must therefore ensure that the engine oil pressure is always maintained at its recommended level for your Toyota Corolla. This represents 1 bar at standstill and about 5 bars at high speed. In a logical way, when the pressure does not reach 1 bar, a sensor should indicate it by lighting the warning light that should alert you.

Faults that trigger the ignition of the oil sight glass on your Toyota Corolla:

Three factors could result in the ignition of this light. First, the most likely, if the oil pump is defective. It no longer fulfils its function of keeping up oil pressure in the engine. If this is the case, we would suggest that you go to a garage because only a professional can make an appropriate diagnosis on your Toyota Corolla.
Secondly, if you run out of oil, the pressure could drop. Same consequence with low pressure, the red LED lights up. So what you have to do is put more oil. The last, rarer case is a defective pressure sensor that can no longer detect the pressure correctly and therefore sends incorrect information. In this case, it is also necessary to call upon a professional for your Toyota Corolla as he will have the pressure control equipment and will be able to tell you exactly what it is.

Conclusion :

So now you know what this light is for and what the related failures are on your Toyota Corolla. Once again, be extremely vigilant when a red light comes on as they stand for a real immediate danger to your Toyota Corolla and especially to passengers.
