Common 'diseases' in car cooling and lubrication systems

(Baonghean.vn) - The cooling system and the lubrication system are two important parts that help cars operate smoothly. However, these two parts also have many damages that drivers need to know to detect and repair.

1. Oil pressure is lower than standard

When this phenomenon occurs, the car owner needs to check the oil pump, because the oil pump may be damaged. In addition, the oil pump's pressure regulator valve may also be damaged. Next, the details of the piston group - connecting rod are worn, or leak oil. It is also possible that the lubricating oil pressure gauge is damaged, the viscosity of the lubricating oil is reduced, causing the car to have this error.

2. The oil level at the bottom of the engine crankcase is not correct.

If you check and find that the oil level at the bottom of the engine is not as specified, it means that the oil level has decreased or increased. It is also possible that the oil is consumed a lot in the air compressor, so check the related parts to best fix it when you see that the oil level at the bottom of the engine crankcase is not as specified.

3. Poor quality engine oil

In addition, if the quality of the oil in the engine is found to be substandard, it may be that the oil is diluted, the oil is dirty, the oil filter is dirty, or the owner of the vehicle has not changed the engine oil on time. If this situation occurs without taking remedial measures, the engine parts will wear out very quickly, leading to engine failure.

4. The radiator is clogged

The radiator is made up of small, narrow pipes and over time, rust will accumulate and clog the pipes. At that time, the water flow will not be able to flow through the radiator, causing the water to not cool well, increasing the pressure on the lines and easily causing leaks. To handle this phenomenon, you need to check by flushing the radiator and should clear the radiator if there is a phenomenon of clogged water pipes to ensure the cooling of the radiator.

5. Cooling system leak

If the car is running fast and the engine is hot, and the cooling system is leaking, you need to check the hoses immediately because they may be damaged. Next, a damaged water pump gasket and a damaged water pump shaft seal ring are also the causes of a leak in the cooling system, causing the car to quickly heat up, with a high risk of damage and explosion.

6. The coolant tank overflows.

If this phenomenon occurs, the gasket between the cover and the engine body may be damaged, the cylinder head cover may not be tightened tightly, or the radiator of the cooling system may be clogged. In addition, it may be due to cracks in the engine cylinder.

7. Broken water pump

The water pump is responsible for circulating the coolant in the cooling system. If the pump is damaged, the water flow will not be able to circulate and cause the engine to overheat. Water pumps usually have a fairly long life, but they can also fail sooner. When the pump is damaged, you must replace it to ensure the engine's operation.
