What is the correct procedure regarding loosening the drain plug during an oil change?

During an oil change, the procedure for loosening the drain plug is crucial to ensure both safety and efficiency. The correct approach typically involves several important steps.

Firstly, it is essential to allow the engine to cool down before beginning the oil change process. Hot oil can lead to burns or injuries and could result in damage to the oil system. Therefore, if either of the choices suggests loosening the drain plug while the engine or oil is still hot, that would be incorrect.

Secondly, the appropriate tools should be used to loosen the drain plug. Using the wrong tool can strip the plug threads or damage the oil pan.

Additionally, it’s standard practice to place an oil drain pan beneath the plug to catch the old oil as it drains out. This prevents spills and makes for a cleaner operation.

If the provided options did not align with these best practices, particularly in relation to safety and proper procedures, the chosen answer reflects that neither option provides a suitable method for loosening the drain plug during an oil change. Understanding the correct procedure helps in performing maintenance tasks safely and effectively.
