The function of the car radiator
The core function of the radiator is to maintain the normal operating temperature of the engine, absorb and dissipate the heat generated by the engine through the coolant circulation to prevent the engine from overheating or overcooling .
Youdaoplaceholder0 Core function
Youdaoplaceholder0 Heat dissipation and cooling : The radiator absorbs the heat from the engine block through the circulation of coolant, and then dissipates the heat through the convection of the radiator fins with the air, preventing the engine from being damaged by high temperature.
Youdaoplaceholder0 Temperature adjustment :
At high temperatures: The coolant absorbs heat and releases it through the radiator, keeping the engine within an appropriate temperature range (typically 80-100℃).
At low temperatures: Stop the water circulation or use antifreeze to prevent the engine temperature from being too low and affecting performance.
Youdaoplaceholder0 Accessibility
Youdaoplaceholder0 Antifreeze protection : The coolant prevents freezing in the radiator and inside the engine at low temperatures.
Youdaoplaceholder0 Lubrication & Anti-corrosion : Some coolants contain additives that reduce friction of components and prevent corrosion of waterways.
Youdaoplaceholder0 Pressure Management : The radiator cap regulates system pressure through a pressure relief valve to prevent coolant boiling or pipe burst.
Youdaoplaceholder0 Structural principle
Youdaoplaceholder0 Circulation system : The water pump drives the coolant to circulate between the engine waterways and the radiator, forming a closed loop of "heat absorption - heat dissipation".
Youdaoplaceholder0 Key components : The radiator core, water supply and drainage chamber, radiator fins, etc. work together to enhance the efficiency of heat exchange.

When the radiator of a CAR is DAMAGED, you must STOP driving IMMEDIATELY and REPAIR IT IN TIME OTHERWISE it may cause engine heat damage, coolant leak or even vehicle paralysis. The specific treatment plan should be selected based on the degree of damage, either replacement or emergency repair. The repair cost usually ranges from 1,000 to 1,400 yuan.
Youdaoplaceholder0 Common symptoms of a damaged tank
Youdaoplaceholder0 Abnormally high water temperature : The water temperature warning light on the dashboard is on, obvious high temperature appears in the engine compartment;
Youdaoplaceholder0 Coolant leak : Green/pink liquid remains on the ground or beneath the engine compartment;
Youdaoplaceholder0 Reduced heat dissipation : The cooling effect of the air conditioning is weakened, and the power of the vehicle decreases significantly when accelerating.
Youdaoplaceholder0 Emergency measures
Youdaoplaceholder0 Stop immediately and check :
Turn off the air conditioning system and open the hood to accelerate heat dissipation.
Check whether there are cracks, rust or marks of external force impact on the surface of the water tank.
Youdaoplaceholder0 Replenish coolant :
For short-distance emergency use only. It should be added in a 1:1 ratio of the original factory antifreeze to water. Do not directly add tap water.
Youdaoplaceholder0 Traffic limits :
If the water temperature exceeds 90℃, a trailer is the safest option.
In extreme circumstances, it is allowed to travel at a speed lower than 40km/h for no more than 5 kilometers.
