What Causes a Car's Temperature Gauge to Read Too High?
1 Answers
If a car's temperature gauge reads high, it may be due to the following reasons: 1. Insufficient engine coolant. 2. Faulty temperature sensor or gauge. 3. Driving with a tailwind or prolonged low-speed, high-load driving in hot weather. 4. Incorrect ignition timing (too early or too late). 5. The radiator shutter not opening fully. 6. Air-fuel mixture being too lean or too rich. 7. A dirty radiator exterior or severe internal scale buildup, leading to poor heat dissipation, requiring radiator cleaning or replacement. Additional information regarding high engine temperature: 1. If the car's engine radiator temperature is too high, pull over to a safe area. Set up a warning sign, open the engine hood, turn off the engine, and wait until the engine's temperature has sufficiently dropped before checking the coolant level. 2. Inspect the engine radiator water level and top it up if necessary. Then, examine the entire cooling system, including the radiator, cooling fan, thermostat, and water pump, to ensure they are functioning properly. 3. Excessive engine temperature can damage many engine components, such as pistons, piston rings, piston pins, cylinder head gaskets, bearings (big and small ends), intake and exhaust valves, oil seals, cylinder heads, and cylinder blocks.
