The maximum power output is also improved, reaching 63 kw at 2400 revolutions per minute. The maximum torque output is 190 N·m at 1300 revolutions per minute. The LJ465Q-2 engine has a higher power output and is suitable for applications in medium-sized trucks. The emissions of this engine meet the national 3 standards.

• LJ465Q-3 engine:

  The LJ465Q-3 engine has the same basic parameters as the other two engines, with a bore of 105 mm, a stroke of 120 mm, and a displacement of 2.54 L. Its maximum power output is 70 kw at 2400 revolutions per minute and a maximum torque of 210 N·m at 1300 revolutions per minute. Because the power and torque of the LJ465Q-3 engine are further improved, it is suitable for heavy-duty trucks and meets the national 3 standards.

In summary, the three types of LJ465Q engines all have the same basic structural features and basic parameters. The bore, stroke, and total displacement of the engines are 105 mm, 120 mm, and 2.54 L, respectively. The main differences between these engines are power output, torque output, and application fields. The LJ465Q-1 engine is used in light trucks, while the LJ465Q-2 and LJ465Q-3 engines are used in medium and heavy-duty trucks, respectively.

Specifications and Maintenance of LJ465Q Engine

The specifications and maintenance requirements of the LJ465Q engine are as follows.

• Cooling system

  The LJ465Q engine has a cooling system that works using a coolant water. This water is circulated through and around the engine block and cylinder head by the water pump. The water pump is belt-driven. The coolant water is also circulated through the radiator and back to the engine block and cylinder head. The coolant water in the radiator is cooled down by the air that flows through the radiator when the vehicle is in motion. The cooling system also has a thermostat that controls the temperature of the water. The water temperature increases when the engine is running. The thermostat automatically closes the valve and prevents the water from flowing to the radiator until the temperature reaches the set level. At the set temperature, the valve partially opens to let a portion of the water pass through to the radiator and maintain the required temperature.

• Oil

  The LJ465Q engine uses lubricating oil to lubricate its internal parts and reduce friction between moving parts. The oil forms a film between the moving parts to prevent wear and tear. This oil also cools down hot parts of the engine by transferring heat to the oil sump. The oil sump stores the oil and acts as a reservoir. The oil is also used to clean engine parts by carrying away debris and dirt, and it helps seal the gap between the piston rings and the cylinder walls.

• Fuel supply system

  The LJ465Q engine is a gasoline engine, and it uses gasoline as fuel. The fuel supply system comprises a fuel tank that stores the gasoline, a fuel pump that supplies the fuel from the tank to the engine, and a fuel filter that cleanss the fuel by removing dirt, debris, and impurities. The system also has fuel injectors that spray the fuel into the combustion chamber in a fine mist, ensuring proper mixing of the fuel with air. The fuel supply system also regulates fuel pressure and controls the fuel quantity delivered to the engine.

• Engine oil

  The engine oil needs to be changed regularly as per the manufacturer's recommendations. The oil change interval could be after a certain number of miles or after a certain period has elapsed. The engine oil level should be checked at every fuel stop. It is also important to use the recommended oil grade.

• Oil filter

  The oil filter needs to be replaced every time the oil is changed. This is usually done after every 5,000 kilometers. It is important to always use a genuine oil filter that is compatible with the LJ465Q engine.

• Cooling system

  The cooling system needs to be flushed and cleaned every 40,000 kilometers. The coolant also needs to be replaced after a specific period or after a certain number of kilometers, as recommended by the manufacturer. The coolant level should also be checked at every fuel stop.

• Air filter

  The air filter in the air intake system of the LJ465Q engine needs to be inspected every 10,000 kilometers. It should be cleaned to remove dust and debris and ensure the efficient operation of the engine. The air filter should be replaced after 40,000 kilometers.

• Fuel system

  The fuel filter of the fuel system in the LJ465Q engine should be replaced after every 40,000 kilometers. Fuel injector cleaning is also recommended after the same distance.

• Valves

  The valve clearance in the engine needs to be checked and adjusted as necessary after every 40,000 kilometers. This will ensure the proper opening and closing of the valves and optimal engine performance.

How to Choose LJ465Q Engine

Choosing the right LJ465Q engine can be a daunting task. Here are some tips to consider:

• Consider what the vehicle will be used for and the engine's ability to perform such tasks.
• Take into consideration the size and weight of the vehicle. Heavier vehicles require more powerful engines.
• The cost of the engine itself and the cost of fuel, maintenance, and insurance that will be incurred should be considered.
• Ensure that the engine chosen meets the environmental standards in the area where the vehicle will be used.
• Before choosing an engine, consider the availability of replacement parts and the ease of which maintenance can be carried out.

How to DIY and Replace of Lj465q Engine

With the right tools and knowledge, replacing an Lj465Q engine can be a manageable task.

• Step 1: Gather all the necessary tools for the replacement, including wrenches, sockets, and an engine hoist. Have a clean workspace to organize parts and tools.
• Step 2: Disconnect the battery and drain the engine oil and coolant. This prevents accidents and protects the environment from harmful fluids.
• Step 3: Remove the front grille and cooling system to access the engine better. Start by removing the radiator hoses and mounting bolts.
• Step 4: Unbolt the engine from the transmission and carefully lift it out using an engine hoist. Replace the old engine with the new Lj465Q engine while aligning it with the transmission.
• Step 5: Reconnect all electrical systems, fuel systems, and exhaust connections. Double-check for any leaks or loose connections that may arise during the replacement process.
• Step 6: Refill the engine oil and coolant before starting the engine. This ensures proper lubrication and cooling for the new engine.
• Step 7: Reassemble any removed components, such as the front grille and cooling system. Take your time to ensure everything is put back in place.
• Step 8: Reconnect the battery and perform a final check before starting the engine. Make sure all systems are functioning properly and there are no visible leaks.
• Start the engine and let it run for a few minutes. Listen for any unusual noises and monitor the temperature to ensure everything is working as it should.
