What are the causes of overheating water temperature?

The causes of overheating water temperature are: 1. Insufficient antifreeze; 2. Leakage at various pipe connections; 3. Blockage due to prolonged use of the radiator; 4. Damage to the engine's cylinder gasket, allowing water to mix with the engine oil; 5. Breakage of the water pump belt or damage to the water pump; 6. The fan not working, preventing the engine water temperature from decreasing. Solutions for overheating water temperature: 1. Idle the vehicle, open the hood, turn on the heater to dissipate heat as quickly as possible, and park in a shaded area; 2. Check if the coolant is sufficient; 3. Check if the cooling fan is functioning properly. If the fan is stuck or the fuse is blown, it can be resolved by disconnecting the power supply.

I've been driving for almost twenty years. The most common cause of overheating is low or deteriorated coolant, possibly due to a leaking hose or aging radiator seal. Radiator blockage is also an issue—excessive dust slows down heat dissipation, and a broken fan becomes especially noticeable when stopping at red lights in summer. Water pump wear and leakage often occur, leading to insufficient cooling system pressure. A stuck thermostat can also prevent water circulation. Once the temperature gauge rises, you must immediately pull over and shut off the engine to avoid cylinder burning or deformation, which can cost thousands in repairs. Make it a habit to check antifreeze levels monthly, use reputable brand fluids, and clean the radiator before long trips.

Having worked in a repair shop for eight years, I generally check three areas when encountering high coolant temperature: Coolant leaks are the most common, possibly due to hose ruptures or loose connections; water pump failure leading to poor water circulation; and a stuck thermostat failing to open, which can block the system. Fan relay or motor failure causing the fan not to spin is also a frequent cause, especially in traffic jams. Cloudy or oily coolant indicates internal leakage into the engine oil, requiring professional inspection. Using a multimeter to measure pressure can pinpoint the issue. Long-term overheating may cause cylinder scuffing, making repairs difficult and costly. Routine maintenance, such as oil changes, should include checking cooling system components to prevent problems.

When I was a new driver, I encountered an overheating issue and was really nervous. Upon checking, I found the coolant level was a bit low, probably due to a leak or a clogged radiator with too much dirt. A non-working fan can also cause this, especially in stop-and-go city traffic where the temperature rises quickly. I temporarily fixed it by adding some coolant myself, but later at the repair shop, they found the water pump was old and leaking. I recommend new drivers regularly check the dashboard and address any high temperature readings promptly to avoid damaging engine parts. Also, don’t forget to clean debris under the hood during regular car washes.

As a family car owner, excessively high water temperature is extremely dangerous. A failed cooling system can directly cause engine overheating or even explosion and cylinder damage. Causes include insufficient antifreeze, blocked pipes, or a broken fan motor. A faulty thermostat or broken belt can also lead to temperature rise. If the water temperature suddenly spikes on the highway, immediately turn on the hazard lights, pull over, and turn off the engine. Check the fluid level after cooling down, and add water if necessary for emergency. Ignoring it may damage transmission linkage components. Remember to test the coolant density and fan performance every six months during maintenance, and pay extra attention during high-temperature seasons.
