Does the Engine Need an Overhaul if Coolant Enters It?

Generally, when coolant enters the engine, it primarily mixes with the engine oil. The combination of coolant and oil causes an emulsification reaction. Once the oil emulsifies, it can no longer effectively protect the engine and may lead to cylinder scoring. Therefore, if coolant enters the engine, an overhaul is necessary. Coolant: The full name of coolant should be antifreeze coolant, meaning it is a cooling liquid with antifreeze properties. Coolant prevents the liquid from freezing and expanding in cold winter conditions, which could otherwise crack the radiator or damage the engine block or cylinder head. Car Engine Maintenance: Use the appropriate grade of lubricating oil: For gasoline engines, select SD to SF grade motor oil based on the additional equipment in the intake and exhaust systems and usage conditions. For diesel engines, choose CB to CD grade diesel oil according to mechanical load, with the standard being no lower than the manufacturer's requirements. Regularly change the oil and oil filter: The quality of any grade of lubricating oil will degrade over time. After a certain mileage, the performance deteriorates, leading to various engine issues. Maintain good crankcase ventilation: Most gasoline engines today are equipped with a PCV valve (Positive Crankcase Ventilation) to facilitate engine ventilation. However, contaminants from blow-by gases can accumulate around the PCV valve and potentially clog it. Regularly clean the crankcase: During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls. These mix with metal particles from component wear, forming sludge. Regularly maintain the radiator: Rust and scale buildup in the engine radiator are common issues. Rust and scale restrict the flow of coolant in the cooling system, reducing heat dissipation and causing engine overheating or even damage.

Can the car still be driven if the engine is shaking?

If the engine is shaking but the malfunction indicator light is not on, you can continue driving, but it is advisable to drive at a lower speed and proceed to a repair shop as soon as possible to diagnose the cause of the shaking. However, if the car shakes violently and the malfunction indicator light is on, you should stop immediately and call for assistance. Possible causes of engine shaking include: 1. Engine misfire: One or more cylinders are not functioning properly; 2. Worn or loose engine mounts; 3. Carbon buildup issues: Including carbon deposits in the cylinders, throttle body, spark plugs, or intake system; 4. Fuel system problems: Using an incompatible fuel grade can reduce engine output and performance.

What Causes Shaking When Starting an Automatic Car?

The reasons for shaking when starting an automatic car are: 1. A dirty throttle body causing uneven air intake and uneven operation leading to shaking; 2. Clogged fuel lines causing insufficient fuel supply at low throttle, resulting in uneven operation of engine cylinders and shaking; 3. Transmission malfunction preventing normal operation. The correct steps to start an automatic car are: 1. Turn the ignition key to the power position to initiate the car's computer system self-check for about 6 seconds; 2. Press the foot brake and shift the gear from P to N, then turn the ignition key to the start position to fire up the engine after releasing the foot brake; 3. Press the foot brake, release the handbrake, shift from N to D gear, and slowly release the foot brake.

How Often Should You Change the Oil for a Sedan?

Different types of motor oil have different replacement cycles. Mineral oil can be changed every 5,000 kilometers or 6 months; semi-synthetic oil can be changed every 7,500 kilometers or within 6 months; and full-synthetic oil can be changed every 10,000 kilometers or 12 months. The steps for changing the oil are as follows: 1. Run the engine until it reaches operating temperature; 2. Engage the handbrake and lift the vehicle; 3. Unscrew the oil filter and drain the old oil; 4. Apply new oil to the gasket of the new filter; 5. Pour the new oil into the oil pan; 6. Check the lower part of the engine for leaks; 7. Lower the vehicle, check the oil dipstick, and start the engine; 8. Turn off the engine and recheck the oil level.
