What causes "overheating" in engines, and what should a QMED do?

Overheating in engines is primarily caused by factors such as low coolant levels, blockages in the cooling system, or malfunctioning components like water pumps or thermostats. When these issues arise, the engine may struggle to dissipate heat effectively, leading to elevated temperatures that can cause significant damage if not addressed promptly.

In the context of a QMED's responsibilities, it is essential to diagnose the underlying cause of the overheating rather than just addressing symptoms. This involves checking coolant levels, inspecting for any obstructions in the cooling systems, and ensuring that all components are functioning properly. Once the root cause is identified, the QMED can take appropriate steps to remedy the situation, which might include adding coolant, clearing blockages, or repairing or replacing malfunctioning parts. This comprehensive approach not only helps in resolving the immediate issue but also aids in preventing future overheating incidents, ensuring the safe and efficient operation of the engine.
