Diesel Generators – Troubleshooting Cooling System Issues

Diesel Generators can have issues with the cooling systems.
Here we offer advice for on site checking of what to check before calling an engineer.
Operator’s Maintenance
The most important link in the maintenance chain is the engine operator. His daily and weekly checks of the cooling system and reports on any questionable conditions he observes will help prevent engine breakdown on the job and provide valuable information to engine repair people.
Each must be recorded and reported as and when they are found.


Diesel Generator Checks Before Start-up
1. Water level.
2. Cleanliness of coolant.
3. Radiator cap gasket.
4. Hose and connections for leaks or hose collapse.
5. Engine lubricating oil level.
Note
Oil level too low or too high will cause overheating and possible loss of the coolant.
6. Check for water in the oil and vice versa.
7. Inspect the fan for bent or damaged blades.
8. Check the belt for tension and condition.
9. Inspect the radiator for bent core fins or accumulation of debris. Check shutters for
damage or linkage wear.
10. Check for leaks at the cooler, water pump, or other accessories.

Diesel Generator Complaints and Causes
Loss of coolant due to external leakage.
1. Leaking pipe plugs, such as core plugs, which seal off coolant passages.
2. Loose clamps, faulty hose and piping.
3. Leaking radiator: Core hole plugs are sometimes loosened by corrosion or vibration.
These same conditions, or frozen coolant, can cause core seals to open up.
4. Leaking radiator, de-aeration top tank or surge tank.
5. Leaking gaskets due to improper tightening of cap screws, uneven gasket surfaces or
faulty gasket installation.
6. Leaking drain cocks.
7. Leaking water pump: Badly worn or deteriorated seals are the cause of leaks at the
pump. Premature failure of the pump seals often results from suspended abrasive
materials in the cooling system, or excessive heat from lack of coolant or cavitation.
8. Leaks at engine cylinder head gasket.
9. Leaks at upper cylinder liner counter bore.
10. Leaking engine or auxiliary oil cooler.
11. Leaking air intake after cooler (intake air heater in some cases).
12. Leaking water manifold and/or connections.

Please, what is or are the diference(s) between Mikano, Jubaili, Marapco,MANTRAC, FG Wilson generators. Oga, which one is better.
