Symptom: The engine coolant temperature rises rapidly under load, triggering alarms.
Solution: First, check the fan belt tensioner and radiator cleanliness. If issues persist, the Cylinder Head Gasket may be breached, causing combustion gases to enter the cooling system. Replacing the gasket and checking the Cylinder Head for flatness is the recommended maintenance plan.
