Common 'diseases' in car cooling and lubrication systems
(Baonghean.vn) - The cooling system and the lubrication system are two important parts that help the car run 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 is the details of the piston group - connecting rod is worn, or oil leaks. It may also be due to a damaged lubricating oil pressure gauge, the viscosity of the lubricating oil decreases, causing the car to have this error.
2. The oil level at the bottom of the engine crankcase is not correct.
If you check that the oil level at the bottom of the engine is not as specified, it means that the oil level is reduced or increased. It is also possible that the oil is consumed a lot in the air compressor, so check the related parts to fix the best solution 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 engine oil is found to be substandard, it may be that the oil is diluted, the oil is dirty, the oil filter is dirty, or the car owner has not changed the engine oil on time. If this situation occurs without remedial measures, the engine parts will wear out, 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. Then 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, the water pump seal is damaged, the water pump shaft seal is damaged, which is also the cause of the cooling system leaking, 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 of the cover with the engine body may be damaged, the cylinder head is not 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.
