How to Check the Coolant Level of Diesel Generator Set?

The coolant in a diesel generator set plays a vital role in maintaining the operating temperature and ensuring the overall performance of the engine. Here are some of the key functions of diesel generator set coolants.

 

Heat Dissipation: During operation, the engine of a diesel generator set produces a large amount of heat. Coolant circulates in the engine’s cooling system, absorbing heat from engine components and transferring the heat to the radiator. This process can dissipate excess heat and prevent abnormal operation or failure of the equipment caused by engine overheating.

 

Temperature Regulation: The coolant absorbs heat and ensures that the engine is within the optimum operating temperature range, preventing the engine from overheating or overcooling and ensuring efficient combustion and overall performance.

Freeze and Boil Protection: Coolant also prevents the engine’s cooling system from freezing in cold weather or boiling over in hot conditions. It has an antifreeze function that lowers the freezing point and raises the boiling point of the coolant, allowing the engine to perform optimally in different environmental conditions.

 

Regular maintenance of the coolant system, including monitoring coolant levels, checking for leaks, and replacing the coolant at recommended intervals, is essential to ensuring the proper functioning and longevity of the diesel generator set.

 

To check the coolant level of the diesel generator set, AGG has the following recommendations:

 

1.Locate the coolant expansion tank. It is usually a clear or translucent reservoir located near the radiator or engine.
2.Make sure the generator set is turned off and cooled down. Avoid contact with hot or pressurized coolant as this may cause safety problems.
3.Check the coolant level in the expansion tank. There are usually minimum and maximum indicators on the side of the tank. Make sure the coolant level is between the minimum and maximum indicators.
4.Refill the coolant in time. Add coolant promptly when the coolant level falls below the minimum indicator. Use the recommended coolant specified in the manufacturer’s manual and do not mix different types of coolants to ensure proper operation of the unit.
5.Slowly pour coolant into the expansion tank until the desired level is reached. Be careful not to underfill or overfill, resulting in insufficient coolant or overflow during engine operation.
6.Make sure the cap on the expansion tank is securely fastened.
7.Start the diesel generator set and let it run for a few minutes to circulate the coolant throughout the system.
8.After the generator set has been running for a while, recheck the coolant level. If necessary, refill coolant to the recommended level.

Remember to consult the generator set’s manual for specific instructions related to coolant checking and maintenance.
