Common problems
15- Starter motor does not rotate
Cause: Flat batteries - Engine does not reach correct operating speed at full throttle
Cause: Lack of fuel: fuel taps closed; fuel tank empty/wrong tank connected - Engine starts but stops again
Cause: Lack of fuel: fuel taps closed; fuel tank empty/wrong tank connected - Starter motor rotates normally but engine does not start
Cause: Lack of fuel: fuel taps closed; fuel tank empty/wrong tank connected - High fuel consumption
Cause: Water/contamination in fuel - Excessive coolant temperature
Cause: Coolant level too low - Starter motor rotates slowly
Cause: Flat batteries - No, or poor charge
Cause: Poor contact/open circuit in cables - Engine runs roughly
Cause: Blocked fuel filter/pre-filter (because of contamination, or paraffin fraction separation in fuel at low temperature). - Blue or white exhaust smoke
Cause: Too low coolant temperature - Black exhaust smoke
Cause: Water/contamination in fuel - Water in fuel — Warning lamp lights up. 2.1
Cause: Water in fuel.
Fix: Empty the primary fuel filter. - Unit injector: cylinder #1 — Engine runs on 5 cylinders. Abnormal sound. Reduced performance. Cylinder balancing is stopped -> Less even running at lower speeds and low loading. 7.1
Cause: Electrical fault; Faulty compression or unit injector.
Fix: Check contact pressure in socket 24 in the upper cable connector (A) on the engine management module; Check that the unit injector cables are not damaged; Check that the unit injector connections are not damaged; Check fuel supply pressure; Check the valve clearance; Do a compression test and check cylinder #1. - Too low lubrication oil pressure
Cause: Too low oil level - Too low coolant temperature
Cause: Defective thermostat

Procedures
4Coolant check (monitoring condition) diagnostic
Tools: pH-measuring device (part 2913 0029 00), Refractometer (part 2913 0028 00)
- Verify the coolant color visually and confirm no loose particles are floating.
- Check the pH value with a pH-measuring device; typical EG value is 8.6.
- Check glycol concentration with a refractometer; keep above 33 vol.%, not above 68 vol.%.
- Replace coolant if pH is below 7 or above 9.5, or if condition is outside limits.
- Always top up with PARCOOL EG only, never with water alone.
Measuring the alternator insulation resistance diagnostic
Tools: 500 V megger
- Disconnect the N-terminal from the earthing system if connected.
- Disconnect the AVR.
- Connect a 500 V megger between the earth terminal and terminal L1.
- Generate a voltage of 500 V and read the scale.
- Verify the scale indicates a resistance of at least 2 MΩ.
Replacing the coolant maintenance
⚠ Never remove the cooling system filler cap while coolant is hot; the system may be under pressure.
- Completely drain the entire cooling system.
- Dispose of used coolant per local regulations.
- Flush twice with clean water.
- Determine the required amount of PARCOOL EG and pour into the radiator top tank.
- Run the engine until normal operating temperature is reached to release trapped air, then turn off and let cool.
- Recheck coolant level and add if necessary.
Preparing for operation after storage operation
- Remove the wrapping, VCI paper and silica gel bags.
- Go through the 'Before starting' checklist.
- Consult the engine's operator manual.
- Check that the insulation resistance of the generator exceeds 2 MΩ.
- Replace the fuel filter and fill the fuel tank; vent the fuel system.
- Reinstall and connect the battery, recharged if necessary.
- Submit the generator to a test run.
