Mitsubishi 4D32 Engine: Specs, Configuration, Oil & Service Intervals

Mitsubishi 4D32 Engine Specs

The Mitsubishi 4D32 engine is a reliable and powerful diesel engine that has been used in various applications, including trucks, buses, and industrial machinery. This article will provide you with detailed information about the engine’s specifications, configuration, engine oil specs, and service intervals.

Engine Configuration

The Mitsubishi 4D32 engine is a four-cylinder, water-cooled, direct injection diesel engine. It has a displacement of 3.6 liters (3,601 cc) and a bore and stroke of 98 mm x 105 mm. The engine is equipped with an overhead valve (OHV) configuration, which helps optimize fuel efficiency and performance.

Engine Oil Specs

Using the right engine oil is crucial for maintaining the performance and longevity of the Mitsubishi 4D32 engine. Here are the recommended engine oil specifications:

• Viscosity: The engine oil should have a viscosity of SAE 15W-40, which ensures proper lubrication in both cold and hot weather conditions.
• API Classification: It is recommended to use engine oil with API CF or higher classification. This ensures that the oil provides adequate protection against wear, deposits, and oxidation.
• Oil Capacity: The engine oil capacity for the Mitsubishi 4D32 engine is approximately 8.5 liters.

Service Intervals

Regular maintenance and servicing are essential to keep the Mitsubishi 4D32 engine running smoothly. Here are the recommended service intervals for this engine:

1. Oil Change: It is recommended to change the engine oil every 5,000 kilometers or every 3 months, whichever comes first. Regular oil changes help remove contaminants and maintain optimal engine performance.
2. Oil Filter Replacement: Along with the oil change, it is crucial to replace the oil filter. This should be done at every oil change to ensure proper filtration and prevent debris from circulating in the engine.
3. Air Filter Replacement: The air filter should be inspected regularly and replaced when necessary. A clogged air filter can restrict airflow to the engine, leading to decreased performance and fuel efficiency.
4. Fuel Filter Replacement: The fuel filter should be replaced every 10,000 kilometers or every 6 months. This helps prevent contaminants from reaching the fuel injectors and ensures proper fuel delivery.
5. Timing Belt Replacement: The timing belt should be replaced at the recommended interval, which is typically around 100,000 kilometers or every 5 years. A worn-out timing belt can cause engine damage if it fails.
