If the oil light on your Ford Focus turns on, you have to be bothered. It suggests a potential failure that could ruin your Ford Focus or even put you in danger so be careful and very reactive.
In this article, we want to try to provide you with an answer so that you can know the ins and outs of this sight and thus correct the situation.
What does the oil sight glass look like on your Ford Focus?
First of all, it is important to identify this indicator on your Ford Focus. 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 Ford Focus 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 flawed.
Do not mix up this light with the almost identical yellow one. This one implies that you are almost certainly short of oil.
What is the purpose of the oil indicator light that lights up on your Ford Focus?
Now, we want to explain to you what it is for and why it is very important. Unlike what we may think, it has nothing to do with the oil level in your Ford Focus. In addition, it is there to report a loss of pressure in this engine oil, which can rather quickly damage or even destroy your Ford Focus’s engine. That’s why as soon as it appears on your vehicle, you must stop the car.
then, we will make clear to you what this oil is used for in your Ford Focus’s engine. It works with a set of metal parts, which are constantly in contact and therefore wear out. The oil under pressure consequently ensures the lubrication of these parts to stop them from being damaged. Otherwise, it also serves to cool them down because they heat up quickly when you drive your Ford Focus. At last, the oil also takes away 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 Ford Focus. 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 indicate it by lighting the warning light that should alert you.
Faults that trigger the ignition of the oil sight glass on your Ford Focus:
Three factors could result in the ignition of this light. First, the most likely, if the oil pump is malfunctioning. It no longer fulfils its function of keeping up oil pressure in the engine. If this is the case, we recommend that you go to a garage because only a professional can make an appropriate diagnosis on your Ford Focus.
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 more detect the pressure correctly and therefore delivers incorrect information. In this case, it is also imperative to call upon a professional for your Ford Focus as he will have the pressure control equipment 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 Ford Focus. Once again, be extremely careful when a red light turns on as they stand for a real immediate danger to your Ford Focus and especially to passengers.
