What to Do (& Not Do) When Your Car Overheats
An overheating engine is a serious issue that can cause severe damage if not handled correctly. Whether you’re stuck in traffic or cruising down the highway, knowing what to do—and what to avoid—can save you from costly repairs. Here’s a guide on how to handle an overheating car safely.
Signs That Your Car Is Overheating
Before your engine overheats completely, your car will show warning signs. Be on the lookout for:
| Rising temperature gauge |
| Steam or smoke coming from the hood |
| Warning lights on the dashboard |
| Strange smells, such as burning oil or coolant |
What to Do When Your Car Overheats
1. Pull Over Safely |
| As soon as it’s safe, pull over to the side of the road and turn off the engine. |
2. Turn Off the Air Conditioning |
| Running the A/C puts extra strain on the engine. Instead, turn on the heater to help draw heat away from the engine. |
3. Check Coolant Levels (If Safe) |
| If you have coolant available and the engine has cooled down, carefully check the levels and top it up if needed. |
4. Let the Engine Cool Down |
| Do not open the radiator cap while the engine is hot, as it can spray boiling coolant and cause burns. |
5. Call for Assistance if Needed |
| If the problem persists or you’re unsure, contact a professional mechanic for help. |
What NOT to Do When Your Car Overheats
1. Don’t Keep Driving |
| Driving with an overheating engine can cause severe damage, including a blown head gasket or a warped cylinder head. |
2. Don’t Open the Radiator Cap Immediately |
| The pressure inside the radiator can cause hot coolant to burst out, leading to severe burns. |
3. Don’t Pour Cold Water on the Engine |
| A sudden temperature change can cause engine components to crack due to thermal shock. |
4. Don’t Ignore the Issue |
| Even if your car cools down temporarily, repeated overheating can lead to irreversible damage. |
Preventing Future Car Overheating Issues
Regular maintenance can help prevent overheating problems. Make sure to:
| Check coolant levels regularly |
| Inspect the radiator and hoses for leaks |
| Ensure the thermostat and water pump are functioning properly |
| Have your cooling system flushed according to your manufacturer’s recommendations |

Why Do Engines Overheat? Common Causes & Solutions
An overheating engine is a warning sign you should never ignore. In most cases, the issue stems from a malfunction in the cooling system, preventing heat from escaping the engine compartment. The culprits can range from a cooling system leak, a faulty radiator fan, a failing water pump, low engine oil, or a malfunctioning thermostat. No matter the cause, letting an overheating engine go unchecked can result in severe or even permanent damage.
Cooling System Leak
Your car’s cooling system plays a crucial role in regulating engine temperature by circulating coolant through key components. When a leak occurs, coolant escapes, causing the engine temperature to rise dangerously. Leaks can originate from:
- Cracked hoses
- Worn-out gaskets
- A damaged radiator
- A cracked engine block
Ignoring a coolant leak can lead to overheating and engine damage. Routine inspections and maintenance help catch these issues before they become costly problems.
Failing Water Pump
The water pump is responsible for circulating coolant throughout the engine. If it fails, coolant flow is disrupted, leading to overheating. One of the most common water pump issues is a worn-out impeller, the fan-like component that moves coolant through the system. If the impeller breaks or stops spinning, coolant flow slows or stops, and engine temperatures rise rapidly. When this happens, replacing the water pump is the only solution.
Bad Radiator
Think of the radiator as the cooling system’s command center—it disperses heat absorbed by the coolant. A failing radiator can lead to overheating due to:
- Blocked coolant passages that prevent heat dissipation
- Bent or damaged fins that reduce cooling efficiency
- Leaks that deplete coolant levels
If your radiator isn’t functioning properly, your engine won’t stay cool, leading to serious damage.
Low Engine Oil Level
Engine oil isn’t just for lubrication—it also helps dissipate heat. If oil levels drop too low, engine components experience increased friction, generating excessive heat. Low oil levels can lead to:
- Overheated engine parts
- Increased wear and tear
- Potential engine failure
Regular oil changes prevent these issues, so always check your oil levels and never ignore dashboard warnings.
Thermostat Failure
Your engine’s thermostat regulates coolant flow based on temperature. If the thermostat sticks closed, coolant won’t circulate properly, causing overheating. If it sticks open, the engine may struggle to reach optimal operating temperature, leading to inefficiency. Replacing a faulty thermostat ensures proper engine temperature regulation and prevents overheating.
Prevent Overheating with Regular Maintenance
The best way to prevent engine overheating is routine maintenance and early problem detection. Keep an eye on coolant levels, engine oil, and radiator health, and schedule regular checkups with a professional technician. If your engine shows signs of overheating, don’t wait—get it inspected before serious damage occurs!
