Can You Still Drive When the Water Temperature Warning Light Is On?

[LaJoshua]

When the water temperature warning light is on, you should not continue driving. You need to pull over to the side of the road, then open the engine hood to allow the engine to cool down. Most engines used in cars are water-cooled engines, which rely on coolant circulating continuously within the engine to remove excess heat. Inside the engine, the coolant follows two circulation paths: a major cycle and a minor cycle. If the coolant level is low, never use tap water as a substitute. Tap water contains minerals that can form scale when heated, which may lead to blockages in the engine's water passages. It is recommended that car owners regularly replace the coolant, typically every two years or so for household vehicles.
