COOLANT
Antifreeze coolant prevents parts from overheating. During the operation of the car engine, a lot of heat is generated in engine. In order to create normal working conditions of the engine, it is necessary to cool it. The cooling system can remove 25-30% of the total fuel combustion heat in the engine.
Drive the specified km and change the coolant. If the coolant is not replaced for a long time, it loses its ability to prevent corrosion and not react and oxidize, and causes scale, scum, and dirt on the outer walls of the cooling system and the engine cylinder, and the heat transfer between the combustion chamber and the coolant begins to be poor.
POWER STEERING FLUID
Power steering fluid is used to transmit energy in technical hydraulic systems. Power steering fluid should have excellent lubricating properties, slow drying and good lubricity.
If your steering wheel is a bit stiff or makes a strange noise when you turn the steering wheel, it is time to replace it.
