What are the causes of high temperature in cars?
3 Answers
Car high temperature causes are: 1. Insufficient coolant; 2. Malfunction of the vehicle's cooling fan; 3. Failure of the engine's circulating water pump; 4. Thermostat failure; 5. Blockage in the vehicle's radiator leading to poor heat dissipation; 6. Leakage in water pipes, water pump, or radiator; 7. Leakage in the engine cylinder head gasket. Effects of car high temperature: 1. Reduction in engine power, leading to insufficient power; 2. Decrease in the amount of mixed gas; 3. Reduction in the pressure of the engine cylinders; 4. Excessive wear of internal engine components; 5. Occurrence of tire burning; 6. Increased risk of vehicle self-ignition.
I've encountered overheating issues quite a few times, and there are usually several reasons. The most common one is insufficient coolant, which could be due to a leaking radiator or aged/cracked hoses. A clogged radiator with excessive dust buildup prevents proper heat dissipation, especially noticeable during summer driving. Water pump problems, such as a stuck impeller or damaged bearings, can disrupt the circulation. Fan failure often occurs due to motor issues or broken belts. A malfunctioning thermostat stuck in the closed position blocks coolant circulation. Additionally, insufficient or poor-quality engine oil increases friction and causes rapid temperature rise. I recommend regularly checking the radiator fluid level and cleaning dust from the front of the radiator during bi-annual car washes. If overheating occurs, immediately stop the engine to prevent costly engine damage.
Speaking of car overheating, I once had a close call on the highway that really scared me. Common issues include insufficient coolant—if it leaks, cooling becomes difficult; a failed cooling system where the fan doesn't work or is blocked; or a broken water pump stopping water flow. Safety is key, as overheating can lead to engine seizure or even fire, causing delays at best and danger at worst. I've made it a habit to check the coolant level monthly, ensure the fan operates properly, and use fresh coolant when seasons change. In summer, I avoid driving continuously for too long and park in shaded areas. Prevention is always better than repair.
