1. Regularly vent air to the radiator

Radiator for diesel generators is very important, is to help diesel generators with heat dissipation, in many cases may cause corrosion to the radiator, affect its normal use.Corrosion can be said to be the main cause of radiator failure, because in the process of use, the air in the water will accelerate the corrosion process.Therefore, we should always keep the pipe joints without leakage, and regularly add water to drain air from the top of the radiator to keep the system "airless".


2. Start by setting goals

Radiators should not be partially flooded as this will accelerate corrosion.For generator sets that do not work, all water should be drained or fully filled.If possible, use distilled or natural water and add an appropriate amount of rust inhibitor.


3. Precautions for radiator operation

The coolant in the radiator of a diesel generator is usually very hot and pressurized.Do not clean the radiator or remove the pipe without cooling. Do not work on the radiator or open the fan protection cover while the fan is running.


4. Keep the radiator outside clean

External cleaning: in dusty or dirty environment, the cracks of radiator may be blocked by debris, insects and other things, and this will affect the efficiency of radiator.Regular cleaning of these light deposits can be done with low-pressure hot water plus detergent sprays that spray steam or water from the front of the radiator toward the fan.Spraying in the opposite direction will only bring dirt closer to the center.When using this method, cover the diesel engine and alternator with cloth.


5. Sediment removal in radiator

Stubborn deposits that cannot be removed in the above manner can be removed by removing the radiator and soaking it in hot alkaline water for about 20 minutes and then rinsing it with hot water.If the joints leak and the hard water method is used for a period of time, or because the diesel generator has been running for a period of time and no rust remover is used, the cooling system may be blocked by scale.
