Lubricant pump is considered the "heart" of the car engine - a small part but plays a decisive role in the life and performance of the entire system.
According to statistics from the Vietnam Automobile Engineering Association (VAMA), 60-80% of engine failures are directly related to the lubrication system, of which oil pump failure accounts for the highest rate at 35-40% of cases. The cost of repairing and replacing an engine due to a damaged oil pump can be up to 50-100 million VND, or even higher depending on the level of damage and vehicle model.
With a key role in maintaining the pressure and flow of oil to lubricate moving parts, the oil pump needs to be maintained and checked periodically. However, many car owners still do not really care about this part until there are abnormal signs such as the oil pressure warning light coming on, strange noises from the engine or oil leakage. At this point, repairing and restoring the oil pump becomes much more complicated and expensive.
This article will provide in-depth knowledge about the causes of damage. car oil pump, standard inspection and repair procedures as well as repair experiences and prevention methods. Don't miss it!
The oil pump plays a key role in the engine lubrication system by creating pressure (30-70 psi) to deliver oil to moving parts, helping to reduce friction, dissipate heat, clean and protect the engine from wear. If the oil pump fails, the engine can be seriously damaged within minutes of operation due to lack of lubrication.
The engine lubrication system consists of the following main components: oil pump, oil filter, oil lines, oil injector pans and lubricated parts. The oil pump draws oil from the engine pan and pumps it up at a certain pressure, usually ranging from 30-70 psi (pounds per square inch – pressure unit).
For good oil circulation, oil pressure needs to be maintained at a stable range of:
After being pumped up at high pressure, the oil will pass through the filter to remove impurities larger than 20 micrometers and flow through the oil pipes to the parts that need lubrication such as crankshaft, piston, piston rings, valves, camshaft, etc.
The oil pump has the function of creating oil pressure to bring oil to the moving parts of the engine. The oil will now perform important functions:
If the oil pump cannot create a large enough and stable oil pressure, the above effects cannot be performed well, leading to engine damage.
When the oil pump fails, the oil pressure will drop sharply or be lost completely. Then:
Therefore, early detection of signs of oil pump damage and timely treatment is very important.
A damaged oil pump will have some typical symptoms. You need to observe and listen carefully to the engine to detect:
There are many signs that the oil pump is having problems such as: the oil pressure warning light is on, the engine temperature is high, and strange noises from the pump.
As the condition becomes more severe, the vehicle will experience problems such as low oil pressure and difficulty accelerating.
When one of the above signs appears, you need to take your car to the garage for timely inspection and treatment. If left for a long time, the oil pump can completely fail and cause serious consequences for the engine.
There are many subjective and objective reasons that lead to oil pump damage, including:
4 subjective reasons that cause car oil pumps to fail include: not changing oil and oil filters periodically, using oil that is not suitable for the engine, operating the vehicle frequently in overload mode, not periodically maintaining and checking the lubrication system.
There are two objective reasons why car oil pumps fail specifically: harsh operating conditions and oil leaks.
To avoid the above causes of oil pump damage, you need to follow the correct maintenance procedures, use quality oil and operate the vehicle properly.
To accurately determine the condition of the oil pump, you need to conduct a comprehensive inspection of the lubrication system, including:
A visual inspection is the first step in determining the condition of your pump. You should look for:
Use a pressure gauge to check that the oil pressure is at the required level. The ideal pressure is usually between 20 and 80 PSI depending on the vehicle.
The safety valve helps regulate the pressure in the system. Check that this valve is working properly to ensure that the pressure is maintained at a safe level.
Oil leaks are also a warning sign that there is a problem with the system. Check the connections and hoses carefully for any signs of leaks.
Depending on the level of damage to the oil pump, the repair process will vary, but generally includes the following 4 steps:
Disassembly must be done carefully to avoid damaging internal components. You will need to remove the hose and valve before proceeding with disassembling the pump body.
After disassembling, clean all parts with a specialized cleaning solution to remove dirt and impurities. Regular cleaning can extend the life of the device by up to 50%.
If any parts are found to be worn or broken, replace them with genuine spare parts to ensure quality. Using poor quality spare parts can lead to a quick recurrence.
Finally, reassemble all parts in the correct order and test the pump for operation before reinstalling it in the vehicle.
Below are 3 experiences drawn when repairing and restoring specific car oil pumps: choose a reputable garage, use genuine spare parts, pay attention to the warranty policy.
Choosing a reputable garage will help you feel more secure about the quality of the repair as well as the warranty after the repair. Look for garages that have been in operation for many years with positive reviews from customers.
Using genuine spare parts will ensure compatibility and quality for the vehicle's lubrication system. According to a survey, about 70% of users feel more satisfied when using genuine spare parts than counterfeit or fake goods.
Make sure that the garage offers a reasonable warranty for the repairs they perform. The warranty should be at least 6 months to 1 year depending on the type of repair.
Prevention is better than cure, you should pay attention to the following 4 things to avoid oil pump failure: use suitable oil, change oil regularly, do not overload the vehicle, check and maintain the vehicle regularly.
Choosing the right oil for your vehicle’s specifications will help protect your engine better. For example, if your vehicle requires SAE 5W-30 oil, never substitute it with a type that does not meet this standard.
Regularly scheduled oil changes will help maintain optimal engine performance. The ideal oil change interval is typically between 5.000 and 7.500 km, depending on the vehicle and driving conditions.
Avoiding overloading will reduce stress on the lubrication system and extend the life of the pump. According to the manufacturer's recommendations, the maximum load should be strictly observed to ensure safety and operating efficiency.
Performing regular inspections will help detect potential problems before they become serious. A routine inspection every 10.000 km is a good option to maintain the operating condition of your vehicle.
Oil pumps are generally divided into two main types: mechanical oil pumps and electronic pumps. Mechanical pumps use mechanical force from the engine to operate, while electronic pumps use electrical power to control the operation.
You can do a basic check by:
The life of the oil pump depends on many factors such as pump type, oil quality, operating conditions, etc. On average, the oil pump can operate well for about 80.000 - 100.000 km. However, you should check it periodically and replace it when necessary to ensure engine performance.
The oil pump should be replaced when:
The cost of repairing an oil pump depends on the extent of the damage and the type of vehicle. Typically, the cost will range from a few hundred thousand to several million VND.

May 2011 ask cruze car how many missing, ghost check nhot exam here du. To be sure no galati is the lack of viscous fuel, the black socks are lacking. Rather, the work of keeping the new pressure was still bi, for another way of asking
Hi, you, check the oil pump to see if the pressure is enough.
Friendly welcome!
My 2012 car has the same condition as yours, so can you tell me if your car has been repaired, if it can be fixed, then I know what's wrong with it. thank you
Mazda 323 car 97 life, the morning car starts the engine to knock the cup, the engine lasts about 5 minutes to stop the sound, the cause must be the oil pump?
My car Cruze 2012 also has the same condition as yours, so can you tell me if your car has been repaired, if it can be fixed, then I know what's wrong with it. thank you
