How do you fix a car that overheats?
Dealing with an overheating car can be stressful, especially if it happens unexpectedly. At Kevin's Autos, with years of experience in car maintenance and repair, we’ve seen this issue countless times. Overheating can stem from various causes, but with the right approach, you can address the problem effectively and prevent further damage to your vehicle. Here’s a step-by-step guide to help you fix a car that overheats.
Step 1: Pull Over and Turn Off the Engine
If your car starts to overheat, the first and most important step is to pull over to a safe location and turn off the engine. Continuing to drive while the engine is overheating can cause severe damage, such as a blown head gasket or warped engine components. Allow the engine to cool down for at least 15-30 minutes before attempting any further action.
Step 2: Check the Coolant Level
Once the engine has cooled, open the hood and check the coolant reservoir. Low coolant levels are one of the most common causes of overheating. If the coolant is low, follow these steps:
- Ensure the engine is completely cool before opening the radiator cap to avoid burns from hot steam or liquid.
- Add coolant to the reservoir or radiator as needed. If you don’t have coolant, water can be used temporarily in emergencies.
- Inspect for visible leaks around the radiator, hoses, or water pump.
Step 3: Inspect the Radiator and Hoses
Check the radiator and hoses for any signs of damage, such as cracks, leaks, or blockages. A clogged radiator or damaged hose can restrict coolant flow, leading to overheating. If you notice any issues, these components may need to be repaired or replaced.
Step 4: Test the Cooling Fan
The cooling fan helps regulate the engine temperature by drawing air through the radiator. If the fan isn’t working, the engine may overheat, especially in stop-and-go traffic. To test the fan:
- Start the engine and let it idle while monitoring the temperature gauge.
- Check if the fan turns on when the engine reaches operating temperature.
- If the fan doesn’t activate, the issue could be a faulty fan motor, relay, or temperature sensor.
Step 5: Examine the Thermostat
The thermostat regulates the flow of coolant through the engine. If it becomes stuck closed, it can prevent coolant from circulating, causing the engine to overheat. A faulty thermostat will need to be replaced to restore proper cooling system function.
Step 6: Check the Water Pump
The water pump is responsible for circulating coolant throughout the engine. If the pump fails, the coolant won’t flow properly, leading to overheating. Look for signs of a failing water pump, such as coolant leaks near the pump or unusual noises coming from the engine.
Step 7: Seek Professional Assistance
If you’ve followed these steps and your car continues to overheat, it’s time to consult a professional mechanic. At Kevin's Autos, we specialize in diagnosing and repairing overheating issues, ensuring your vehicle is back on the road safely and efficiently. Don’t hesitate to reach out to us for expert assistance.
Preventing Future Overheating
To avoid overheating in the future, follow these maintenance tips:
- Regularly check and top off coolant levels.
- Inspect the radiator, hoses, and water pump for wear and tear.
- Flush and replace the coolant as recommended by your vehicle’s manufacturer.
- Ensure the cooling fan and thermostat are functioning properly.
By staying proactive with maintenance, you can reduce the risk of overheating and keep your car running smoothly. If you have any questions or need assistance, Kevin's Autos is here to help!

- First, turn on the heater. This may sound counterintuitive, but the heat will help draw the engine's heat away.
- Next, turn on the fan.
- Once the engine is cool, check the radiator for any leaks or blockages.
What is the first thing you check when a car is overheating?
Most vehicles will have a temperature gauge on the dashboard. Unfortunately, some think it's simply reflecting the exterior temperature, but it's actually showing how hot the engine is. Reading and checking your automobile's thermostat is essentially the first step to diagnosing an overheated engine.
How much does it cost to fix a car that overheats?
