Can You Shift Directly from Fourth Gear to Neutral?

You can shift directly from fourth gear to neutral. Here are the precautions for shifting into reverse gear: Ensure the vehicle is completely stopped before shifting into reverse. When shifting into reverse, you must press the brake pedal firmly to bring the vehicle to a complete stop before engaging reverse gear. Depress the clutch pedal fully. When shifting gears and pressing the clutch, make sure to press it all the way down. Never shift into reverse while the clutch is still partially engaged, as this can cause gear grinding. Additionally, be gentle when shifting into reverse—avoid using excessive force. Reverse slowly. Finally, when reversing, do not go too fast. Avoid pressing the accelerator pedal harshly for sudden acceleration while reversing, as this can cause significant damage to the straight-cut gears.

What is the normal water temperature for a diesel engine?

Water temperature is optimal between 70-92 degrees Celsius. Thermostat operation: When the water temperature reaches 70-80°C: The thermostat is partially open, allowing coolant from the engine water passages to flow through the partially open thermostat space to the radiator side, achieving a semi-circulation state. When the water temperature reaches 80-92°C: (Note: Some models may vary, this applies to most common market models) The thermostat fully opens, enabling coolant from the engine water passages to flow through the fully open thermostat space to the radiator side in a complete circulation cycle, achieving true circulation. Optimal operating temperature: Through coolant flow and fan operation, engine heat is dissipated to maintain the best working temperature for the engine.
