Radiator blockage is a common problem that may affect the efficiency of the cooling system. According to the search results, common causes of radiator blockage include:
1. Poor water quality: Poor water quality may bring silt and other impurities, which may be deposited inside the radiator, causing blockage.
2. Internal corrosion: If corrosion occurs inside the radiator, the generated rust may accumulate, causing blockage.
3. Air accumulation: In home radiators, air accumulation may cause "air blockage" phenomenon, hindering the circulation of hot water, so that the radiator does not dissipate heat or dissipates heat slowly.
4. Pipe blockage: Pipe blockage will directly affect the working efficiency of the radiator and cause the radiator to be blocked.
5. Overlapping and deformation of the heat sink: If the heat sink overlaps or deforms, it may also cause the radiator to be blocked.
6. Improper adjustment of the pressure limiting valve: If the pressure limiting valve is not adjusted properly, it may affect the pressure of the system, causing the radiator to be blocked.
7. Insufficient coolant: Insufficient coolant will prevent the radiator from effectively exchanging heat, causing blockage.
8. Damaged thermostat: If the thermostat is damaged, it may cause poor circulation of cooling water, which may cause radiator blockage.
9. Air conditioning system problem: Failure of the air conditioning system may increase the load on the engine and cause radiator blockage.
10. Blockage of the engine waterway: Blockage of the engine waterway will reduce the circulating water flow and poor water return, which may cause radiator blockage.
11. Scale accumulation in the water tank: The longer the water tank is used, the thicker the scale inside will accumulate, which may also cause radiator blockage.
12. Too much dust between the condenser and the water tank: Too much dust will affect the heat dissipation between the condenser and the water tank, causing radiator blockage.
13. Water pump failure: If the water pump fails, it may cause poor circulation of the coolant, causing radiator blockage.
14. Electronic fan failure: If the electronic fan does not work properly, it may cause poor engine heat dissipation, causing radiator blockage.
15. Too much air conditioning refrigerant or air conditioning refrigeration lubricant: This will increase the load on the engine and consume the cooling system's heat dissipation performance, resulting in radiator blockage.
Understanding these common causes will help us take corresponding preventive and remedial measures to ensure the normal operation of the radiator. If your radiator is blocked, it is recommended to contact a professional maintenance personnel for inspection and repair in time.
