Yes, engine coolant can evaporate, especially under high-temperature conditions within the engine's cooling system. This evaporation primarily occurs when the coolant heats up, turns into steam, and then might escape through small leaks or the radiator cap, if it's not functioning properly. Over time, this can lead to a reduction in coolant volume within the system. However, it's worth noting that a well-sealed cooling system should minimize coolant loss to evaporation, leading most coolant loss cases to be due to leaks rather than evaporation. Regular checks and maintenance of the cooling system are advised to ensure the coolant levels are appropriate and the system is sealed correctly.

Yes, engine coolant can evaporate over time, particularly if the car's cooling system has a leak or is not functioning properly. However, this is not a common occurrence because the coolant is usually in a closed system and is designed to handle high temperatures. If you notice that your coolant is frequently low, it could be a sign of a leak or other mechanical issue that should be checked by a mechanic.

The BMW B58 engine, introduced in 2015, is a 3.0L inline-6 turbocharged power unit, highly regarded for its blend of performance and reliability. It's part of BMW's modular engine family, allowing for efficient production and maintenance. Critics and owners alike commend the B58 for its robustness, thanks to quality engineering and the use of durable components. While no engine is without potential faults, issues like the crank hub failure in its predecessor (the N54/N55) seem less prevalent here. Regular maintenance is key; with proper care, the B58 exhibits excellent longevity. However, like all high-performance engines, running costs and repair expenses can be high, particularly outside of warranty periods. Overall, the B58 is considered reliable by industry standards, earning it a solid reputation among enthusiasts and professionals.

Adjusting a carburetor on a 2 stroke engine can be a technical task, but essentially there are three main adjustments to be made: the idle speed adjustment, the low speed mixture adjustment, and the high speed mixture adjustment. Here is a step-by-step guide: 1. Warm up the engine: Let your engine run for at least 10 minutes to reach its operating temperature. This will give you a more accurate adjustment. 2. Set the idle speed: Locate the idle speed screw, usually found next to the fuel bowl. Turn the screw clockwise to increase idle speed, and counterclockwise to decrease. The ideal idle speed is around 1,500 RPM. 3. Adjust the low speed mixture: Find the screw labelled "L" or "Low". Gradually turn this screw clockwise until the engine starts to sound rough, then slowly turn it back (counterclockwise) until the engine runs smoothly. 4. Adjust the high speed mixture: Run the engine at full throttle. (Make sure this is safe to do in your situation). Find the screw labelled "H" or "High". Slowly turn this screw clockwise until the engine starts to slow down, then gradually turn it back (counterclockwise) until the engine runs at maximum speed without the sound of being "out of breath". 5. Repeat adjustments: Go back and forth between adjusting the idle speed, low speed mixture, and high speed mixture until the engine performs optimally at both idle and full throttle. 6. Test drive: After making these adjustments, give the vehicle/engine a test drive to make sure it performs well under different operating conditions. Remember that this is a general guide, and the precise locations of the adjustment points can vary significantly between different models and makes of engines. Ensure that you're familiar with your engine and refer to your owner's manual before making any adjustments. Also, pay close attention to any signs of discoloration on the spark plug since it is an excellent indicator of an improperly tuned carburetor. A carbon-fouled plug (dry, black) might indicate a too rich fuel mixture, while a whitish plug might point to a mixture that is too lean. Please be aware, adjusting your carb is often just maintaining and occasionally fixing. If your engine has other issues this may not fix them. Always verify with a professional if you are unsure.
