What are the reasons for abnormal coolant consumption?
1 Answers
The reasons for abnormal coolant consumption are as follows: 1. Decreased heat dissipation capacity of the cooler: Insufficient opening of the shutters; Fan belt is too loose or slips due to oil contamination; The radiator outlet pipe is aged, collapsed, or blocked by internal layer detachment; The cooling fan is installed backwards, or the fan specifications are incorrect; The electric fan does not rotate, or the silicone oil fan clutch is damaged, causing the fan not to rotate or rotate at too low a speed. 2. Increased heat generation by the engine: Ignition timing is too late; The air-fuel mixture is too rich or too lean; Excessive carbon deposits in the combustion chamber; Insufficient engine oil or poor performance of the oil cooler; Influence of vehicle usage conditions (such as road, climate, wind direction, and load, etc.).
