While replacing the car’s oil pump is not something that most drivers face very often, it may sometimes become unavoidable. Odds are that you may never have to change it even once in your or your car’s lifetime. But, you must learn to recognize a bad oil pump, just in case. Because when you have it, you need to replace it.
So, here are 3 symptoms that, at first, may not sound too worrisome to you. But, they may actually be asking you to change the pump ASAP.
Symptoms of a Bad Oil Pump
1. Decrease in Oil Pressure
Since the oil pump is responsible for maintaining the right oil pressure, if any abnormality arises, it will be evident. The pump pressure pushes the oil into the engine and then keeps it moving through the engine. Now, when the oil does not move along with the right pressure, the friction between the parts increases. So, if you feel that the engine is heavy, the power is low, and the car stalls frequently, it is because of decreased oil pressure. And, that is one sure symptom of bad oil pump.
So, it is not just the pump that the constant movement is damaging, but also the engine and the entire vehicle.
2. Increased Engine Operating Temperature
Now, we learned something important in the previous point. The pump maintains the oil pressure to a point as can impart proper lubrication for the functioning of the engine and other machinery without friction.
In the absence of that right pressure, friction will be caused for sure, and the most obvious result then, is heat generation. It is one of the most obvious oil pump failure symptoms. So, as you operate the vehicle, the temperature of the engine will rise beyond normal. And, when this happens, the heat light on your dashboard will light up to alert you about this abnormal rise in engine operating temperature.
This, if left unchecked can lead to colossal damage to the engine as well as other parts, along with a likely breakdown of the car on road (in grave situations). Addressing this issue in time is one of the important ways to save money on car repairs.
3. Unusual Noise
Now, even if you go only by common sense and no mechanical knowledge of any vehicle, friction between parts can still seem an understandable problem. It causes them to rub together and cause noise, just like rustling pines.
Now, if we talk mechanically, a dysfunctional (or a semi-functional) pump can cause the hydraulic lifters to make noise. It leaves them rubbing against other parts without lubrication. These lifters are a vital part of the valve-train mechanism of the vehicle. Low pressure of the oil coming from the pump prevents the oil from reaching the hydraulic lifters. This causes so much friction as produces noise, loud enough to be heard clearly as the vehicle rolls. They also start to wear. Ultimately, irregularities appear if you leave it unchecked. Then, it’s high time you contemplated oil pump replacement to avoid unexpected damage to your car
