If the oil light on your Nissan Altima lights up, it is best to be bothered. It suggests a potential failure that could affect your Nissan Altima or even put you in danger so be careful and very responsive.
In this article, we wish to try to provide you with an answer so that you can understand the ins and outs of this sight and thus correct the situation.
What does the oil sight glass look like on your Nissan Altima?
First of all, it is important to find this indicator on your Nissan Altima. It is red in colour and shows a small burette with a drop on the right. Like all red lights, this suggests that that you must stop your Nissan Altima as soon as possible. To ensure 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 confuse this light with the almost identical yellow one. This one implies that you are probably short of oil.
What is the purpose of the oil indicator light that lights up on your Nissan Altima?
Now, we want to explain to you what it is for and why it is very important. Contrary to what we may think, it has nothing to do with the oil level in your Nissan Altima. In addition, it is there to report a loss of pressure in this engine oil, which can quickly damage or even ruin your Nissan Altima’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 Nissan Altima’s engine. It works with a set of metal parts, which are frequently in contact and therefore need replacing. The oil under pressure consequently ensures the lubrication of these parts to prevent them from being damaged. Otherwise, it also serves to cool them down since they heat up quickly when you drive your Nissan Altima. Finally, the oil also cleans and circulates dirt that may well damage your engine.
You must consequently ensure that the engine oil pressure is always conserved at its recommended level for your Nissan Altima. This represents 1 bar at standstill and about 5 bars at high speed. Logically, when the pressure does not reach 1 bar, a sensor should signal it by lighting the warning light that should alert you.
Faults that trigger the ignition of the oil sight glass on your Nissan Altima:
Three factors could trigger the ignition of this light. First, the most likely, if the oil pump is faulty. It no longer fulfils its function of preserving 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 reliable diagnosis on your Nissan Altima.
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 flawed pressure sensor that can no longer detect the pressure correctly and therefore delivers incorrect information. In this case, it is also imperative to call upon a professional for your Nissan Altima as he will have the pressure control device and will be qualified to tell you exactly what it is.
So now you know what this light is for and what the related failures are on your Nissan Altima. Once again, be extremely careful when a red light comes on as they represent a real immediate danger to your Nissan Altima and especially to passengers.
