What do the H and C on the temperature gauge mean?
1 Answers
"C" stands for the first letter of the English word "cool," meaning cold. "H" stands for the first letter of the English word "hot," meaning hot. The water temperature refers to the temperature of the coolant. After the engine warms up, it usually shows a normal range of 70-90 degrees. When the water level in the cooling tank is low, the temperature will rise, and you need to add water at this time. The reasons for an excessively high car temperature gauge reading are as follows: 1. Insufficient coolant: A leak or low level of coolant can cause the temperature to rise. You should check for any coolant leaks. If there is a leak, the faulty component should be repaired as soon as possible. If there is no leak, the appropriate coolant should be added promptly. 2. Issues with the cooling fan: A malfunctioning cooling fan can cause the temperature to rise. When the vehicle is running at high speeds, the heat generated cannot be transferred to the coolant in time, affecting cooling and leading to an increase in coolant temperature, which can result in overheating. 3. Problems with the water pump: If the water pump fails, it cannot circulate the water on the engine's heat-conducting side properly. This leads to a failure in the engine's cooling system, causing an "overheating" phenomenon.
