| Gross power | 1350 kW |
|---|
| Symptom | Cause | Remedy |
|---|---|---|
| Starter will not crank engine or cranks slowly, resulting in a failure of engine to start | Repair or replace. Battery — starter switch circuit open | |
| Starter will crank engine, but engine will not start | Refuel. Consult Mitsubishi dealer. | |
| Engine lacks power | Incorrect grade of oil, Wrong type of fuel, Insufficient air (air cleaner clogged), Engine overcooled, Fuel feed pump gauze filter clogged | |
| Engine overheating | Valve clearance incorrect, Injection pump defective, Injection nozzles defective, Injection timing incorrect, Compression pressure low (cylinders and pistons worn) | |
| White or blue exhaust smoke | Too much oil in crankcase, Oil viscosity too low | Use radiator cover, or clean, test and replace thermostat. Fill only to correct level on gauge. Refill with correct viscosity of oil. |
| Engine overcooled | Thermostat defective (no water temperature rise) | Use radiator cover, or clean, test and replace thermostat. |
| Injection timing incorrect, Compression pressure low | Readjust. Disassemble and replace parts. Change. | |
| Black or gray exhaust smoke | Wrong type of fuel (low cetane number), Vaive clearance incorrect, Injection pump defective, Compression pressure low, Insufficient air (air cleaner clogged) | Refill with correct type of fuel. Readjust. Readjust or replace. Disassemble and replace parts. Clean or change element. |
| High fuel consumption | Readjust or replace. Disassemble and replace parts. Change. Refill with correct type of fuel. Disassemble and replace parts. Clean or change air cleaner element. Check turbocharger. | |
| High oil consumption | Too high oil level in crankcase, Incorrect grade of oil, Oil leaks, Cylinders and piston rings worn | Maintain oil level in correct range on gauge. Use recommended type and SAE number of oil. Retighten or replace. Disassemble and replace parts. |
| Low oil pressure, Lack of oil | Oil viscosity too low, Oil filter clogged, Oil pump defective, Oil pressure regulating valve defective, Oil pressure sensor circuit defective | Refill up to level. Refill with correct viscosity of oil. Replace element. Readjust, replace or clean. Readjust or replace. |
