Mitsubishi K4N Engine Specs
Engine Configuration
The Mitsubishi K4N engine is a four-cylinder, water-cooled diesel engine with a displacement of 3.331 liters. It features an overhead valve (OHV) design with a cast iron cylinder block and cylinder head. The engine is equipped with a turbocharger to enhance its performance and efficiency.
Engine Oil Specs
To ensure optimal performance and longevity of the Mitsubishi K4N engine, it is crucial to use the recommended engine oil. The engine requires a high-quality diesel engine oil that meets the specifications outlined by Mitsubishi. The recommended oil viscosity for this engine is typically 10W-30 or 15W-40, depending on the operating conditions and climate.
Service Intervals
Regular maintenance is essential to keep the Mitsubishi K4N engine running smoothly. Here are the recommended service intervals for various engine components:
1. Engine Oil Change: It is recommended to change the engine oil every 5,000 to 7,500 kilometers or every six months, whichever comes first. Regular oil changes help to remove contaminants and ensure proper lubrication of engine components.
2. Oil Filter Replacement: Along with the oil change, it is important to replace the oil filter. The oil filter should be replaced every time the engine oil is changed to maintain its filtering efficiency.
3. Air Filter Replacement: The air filter should be inspected regularly and replaced every 10,000 to 15,000 kilometers or as per the manufacturer’s recommendations. A clean air filter ensures proper air flow to the engine, preventing dust and debris from entering the combustion chamber.
4. Fuel Filter Replacement: The fuel filter should be replaced every 20,000 to 30,000 kilometers or as recommended by the manufacturer. A clogged fuel filter can restrict fuel flow and affect engine performance.
5. Coolant Replacement: The engine coolant should be replaced every 40,000 to 60,000 kilometers or every two years, depending on the coolant type. Regular coolant replacement helps prevent overheating and protects the engine from corrosion.
6. Timing Belt Replacement: The timing belt should be replaced at the recommended interval, typically around 100,000 kilometers or as specified by the manufacturer. A worn-out timing belt can lead to engine damage and costly repairs.
