Engine Application
The 6A13 engine was installed in the following vehicle models:
- Mitsubishi Diamante (September 1999 – November 2005) – 2nd restyling, sedan, 2nd generation, F3#A.
- Mitsubishi Galant (August 1998 – October 2003) – restyled, sedan, 8th generation, for the Russian market.
- Mitsubishi Galant (August 1996 – May 2003) – station wagon and sedan, 8th generation, EA0, for the European market.
- Mitsubishi Legnum (August 1996 – July 1998) – station wagon, 1st generation.
Features and Operation
Engine layout: The compact placement of engine components in the engine compartment makes it difficult to access some components, making maintenance difficult.
Typical Malfunctions:
- Hydrocompensators: Can fail over time, causing increased engine noise.
- O idle speed regulator: Subject to wear and tear, which can cause the engine to run erratically at idle speed.
- Timing belt: The timing belt should be changed regularly, as it will damage the valves if it breaks. The belt should be replaced every 90,000 kilometers.
- Heat exchanger: Use of poor quality or old antifreeze can lead to corrosion of the heat exchanger and leaks.
Service and Care Recommendations
- Regular oil changes: It is recommended to use 5W-40 viscosity oil and change it every 10,000 km. The oil capacity is 4.2 liters.
- Checking the condition of the timing belt: It is very important to check the condition of the timing belt and change it at 90,000 km.
- Check antifreeze level: Use quality antifreeze to avoid corrosion of the cooling system.
- Check the oil level: If the oil pressure drops, it may cause the liners to fail.
Mitsubishi 6A13 Engine Advantages and Disadvantages
Advantages:
- Reliable construction and long service life.
- Good power and torque ratings.
- Supports hydrocompensators, which reduces the need for frequent valve adjustments.
Disadvantages:
- The tight layout makes it difficult to access engine components.
- Vulnerability of the cooling system and the need for quality antifreeze.
- Sensitivity to the condition of the timing belt, which can cause serious damage if it breaks.
