What Are the Reasons for Slow Engine Coolant Temperature Rise?
1 Answers
Engine coolant temperature rises slowly due to a damaged thermostat that fails to close or a malfunctioning cooling fan that runs continuously. When the thermostat valve fails to close, the coolant continuously circulates through the large loop, causing the car's coolant temperature to drop rapidly. If the cooling fan malfunctions and keeps running, it will result in lower engine coolant temperature. The function of the engine is to convert the thermal energy of gasoline or diesel into mechanical energy by burning the fuel in a sealed cylinder, which expands the gas and pushes the piston to perform work. Methods for engine maintenance include: 1. Using qualified engine oil; 2. Using qualified coolant and antifreeze; 3. Regularly cleaning the radiator scale; 4. Regularly removing engine carbon deposits; 5. Regularly replacing the car's three filters (air, oil, and fuel filters); 6. Maintaining a reasonable engine speed.
