What to Do When the Water Temperature Warning Light Comes On?

[DelPenelope]

Solutions for when the water temperature warning light comes on: 1. The optimal water temperature while driving is around 90 degrees Celsius. Overheating may lead to boiling. Once the water temperature warning light comes on, it is not advisable to continue driving. You should stop the car and wait for the temperature to drop before driving to a service station for inspection and repair. 2. Do not pour cold water onto the engine to cool it down. Instead, wear gloves, place a wet cloth over the radiator cap, loosen the cap slightly to allow steam to escape, and wait for the radiator pressure to decrease before adding cold water or antifreeze. 3. When encountering a high water temperature warning, first reduce speed and pull over to the roadside. Do not rush to turn off the engine immediately, as excessive water temperature can cause overheating of components like pistons, cylinder walls, and the crankshaft, thinning the engine oil and reducing lubrication. If the engine is turned off at this point, the expanding components may lead to soft metal detachment or even cylinder seizure due to the minimal clearance between parts.
