How To Test An Oil Pump

Updated November 14, 2020 By Richard Shuback

Oil is crucial to the proper functioning of every automobile. It lubricates the moving parts of the engine to avoid them from grinding each other and the oil absorbs excess heat. You should change the oil regularly and use the proper oil weight. Also, make sure that the pump distributes it is in good condition. If you suspect that there is an issue with the pump, you can quickly test and repair it before it causes permanent damage. An oil pump promotes oil circulation and keeps your engine in top condition. In case of a pump failure, most engine parts can wear or burn through friction.

Common symptoms of oil pump errors

The oil light indicator on the dashboard informs you about engine problems. Do not ignore it when it is on, as it may indicate a possible low oil pressure.

Continue to check the dipstick and add oil if the level is low. If the indicator light stays on, this may indicate an error in the oil pump. Other signs include:

i. Overheating of the engine

As already mentioned, vehicles must be well lubricated always. This will avoid friction between the moving parts and thus to regulate their temperature.

If an oil pump fails, the oil distribution will be affected and most moving parts will not be lubricated well. Without proper lubrication, these parts rub against each other and heat up.

ii. Noise

Car engines have hydraulic lifters that work quietly when the engine is working correctly. If they are not lubricated well, they cause excessive noise and may cause uneven wear.

The valve train, which consists of pushrods, seals and valve guides, also makes noise when the engine is not well lubricated. Replacing these components can be very expensive in the long run and the only durable solution is to make sure that the oil reaches all engine parts.

In particular, due to a defect or wear of the internal components, the oil pump may also generate a whirring if it is not appropriately lubricated.

What should you do when testing an oil pump?

It is essential to know what steps to take if you suspect your oil pump is malfunctioning. In essence, you can avoid damage at an early stage before it becomes a severe problem. We can know how to test an oil pump by the following steps: 

i. Stop the vehicle

If you find that the oil pressure gauge is too low, stop the car and check the level of oil on the dipstick. Switch off the vehicle and add oil after a few minutes if the oil level is below the recommended limit. After restarting the engine, check the oil pump for signs of failure.

ii. Check engine oil pressure sender unit

Check the engine oil pressure sending the unit on the engine if the problem persists. If the gauge remains on, there may be an issue with the mechanical transmitter unit. This may be a loose plug in the hole into which oil is entering or faulty wiring.

The worn-out sports that are on the rheostat are the most likely cause of problems with the electrical transmission unit.

iii. Mount the oil pressure gauge on the engine oil connection.

Make sure the oil pressure gauge is attached correctly to the engine oil port. Check the pressure gauge when the engine is running. At this point, the pump may experience some problems if the light does not switch off.

Continue checking the pressure gauge. If the pressure is normal, then the problem may be with the sending unit and not with the oil pump.

Check the filter in the pickup tube and replace it if necessary. At this time, the oil pump may need to be replaced by a mechanic if the problem persists.

How to keep your car engine in top condition?

The best way to avoid significant problems with the engine of your car is to check regularly. You must do the following:

  • Check the oil engine every time you refuel
  • Don’t overfill the crankcase with the oil
  • Change oil regularly
  • Clean the oil pan when changing the oil
  • Use synthetic oil, which is suitable for your engine

Conclusion

Testing an oil pump is one of the necessary procedures that every car owner needs to perform. Even if the process seems simple, you should pay attention to a correct diagnosis.
