How Long Can You Drive a Car Before It Overheats?

Overheating is a major problem that may result in costly repairs, yet it is among the most ignored issues. When you discover that the car is overheated, you should pull over to a secure position and perform a short inspection to identify the reason. If you neglect the heating (for whatever purpose), you may cause severe damage to the vehicle, resulting in a costly engine replacement.

Around 5 miles is the maximum distance an automobile may be driven when heated before severe engine damage occurs. In contrast, some cars may still be able to go up to 15 miles with an overheated engine. But we do not suggest driving much further than 10 miles.

This article answers all the concerns about overheating cars and how the engine will damage if you keep driving.

What Happens If You Continue Driving an Overheating Car?

Most diesel engines generate great heat to keep the machine working. The refrigerant or coolant absorbs heat. If the refrigeration system is malfunctioning, the engine will continue to overheat until it is repaired.

Moreover, operating a car that is overheated might result in a variety of issues, such as:

Faulty Radiators

If the car is overheated with refrigerant still present. In such a situation, the coolant will melt and expand, resulting in high pressures in the radiators. The connections may end up fracturing, causing the refrigerant to overflow. Furthermore, you may see radiator stem failure.

Damaged Engine Components

The majority of engine components can withstand high temperatures. However, they will begin to bend if the average temperature is exceeded. For instance, combustion products are constructed of aluminum, which is capable of rapid melting at extreme temps.

In addition, damaged cylinder heads may result in a damaged engine block, which is among the costliest vehicle maintenance.

Head Gasket Leakage

After dealing with a damaged cylinder head, you will have to deal with a damaged head gasket. Fixing a damaged head gasket would be both time-consuming and costly. In addition, refrigerant and engine fuel will fracture the cylinders if the head gasket fails because the function is to cover the cylinder’s releasing force.

How Long Can a Vehicle Overheat Before Damage Occurs?

It is dangerous to continue driving a vehicle that is overheated. As indicated, the automobile may go a few miles. However, the engine will shut down when the heat reaches its maximum in most instances. So, don’t risk the vehicle by driving it too far.

When a vehicle gets too hot, it is preferable to stop in a secure place. Then switch off the ignition or have the car pulled to a nearby workshop.

What Are the Typical Causes of Excessive Heat?

There are several causes for a vehicle to overheat. If you’re curious about what may be causing the car to overheat, these are the most common reasons.

Low Coolant Level

The refrigeration system of the car depends on coolant to keep the car cool. When the quantity of coolant is low, it is useless in absorbing heat, and that’s how the engine gets overheated. Consequently, the engine temperature may rise, resulting in engine stoppage or locking.

Refrigeration System Starting to Leak

In a fully working car, the refrigerant level should stay constant. Although fractured, broken, worn out, or loosened pipes might be the source of coolant leakage. As a result, the refrigerant will not reach the correct components, causing the vehicle to overheat.

Red, yellow, or purple spots beneath the automobile may be coolant leaks. If you notice any of these when doing regular auto repair, you should not neglect them. Instead, schedule an appointment with a nearby mechanic to resolve the issue.

Damaged Pump System

Propylene glycol and water combine to form a coolant. The coolant is pumped into the different engine parts by a water pump system. However, if it is damaged or broken, it doesn’t provide the engine with enough refrigerant to maintain the engine running at an ideal temperature.

Inefficient Thermostat

Another typical cause of an overheated engine is a malfunctioning thermostat. A thermostat regulates the refrigerant, preventing the engine from getting too hot. Failure of the thermostat results in inaccurate temperature measurements, prohibiting coolant flow as planned. This causes an abnormal temperature rise.

Defected Radiator

The radiator lowers the temperature of the refringent, allowing it to continue collecting heat. Therefore, it will retain the coolant heated and decrease its ability to cool the machine when it malfunctions.

How Do You Repair an Overheating Car?

A vehicle that overheats requires urgent care. However, before taking any further action, you must first stop and turn off the air conditioning and then wait about 45 minutes for the vehicle to cool down.

If you are unable to stop, activate the heater. However, it may seem odd, but starting the heater will draw some of the car’s heat into the interior. The windows must be rolled down to allow the heat to pass at this stage.

After coming to a safe stop and allowing the motor to cool, perform a detailed inspection to see whether the refrigerant is leaking or if the radiator is faulty. You may be able to add refrigerant and drive the car to a repair. If this is not available, the vehicle should be towed to a workshop.

However, experts can determine the source of the problem and avoid engine overheating. Put your vehicle’s VIN and location into an internet booking tool to check garages around you to resolve the issue. You may filter by location, accessibility, and cost to discover the ideal garage.

Frequently Asked Questions

Why is The Vehicle Overheating despite Having Coolant?

If the vehicle has refrigerant but is still overheating, the refrigerant is probably not working as it should. For example, the cooling system may be defective, the radiator may be jammed, or the thermostat blocked.

How to Determine if the Vehicle Is Overheating Without a Temperature Gauge?

You can still determine whether the vehicle is overheating even without a gauge. For example, you may observe white smoke streaming from the exhaust muffler. Alternatively, listen to engine sounds, detect unusual odors, and notice accelerating troubles.

How Can an Overheating Engine Be Detected?

The engine compartment suffers excessive heat as the temperature gauge shifts from the regular side to another side. Occasionally, you may notice smoke emerging from the hood.

Final Note

You shouldn’t worry about how long an overheated vehicle can travel before crashing. Instead, you should be concerned about the vehicle’s potential harm if you drive while the engine is overheating. You risk severe engine damage if you continue driving an overheated car.

We have explained how long you can drive in this article. However, we would still suggest that you take the car to a professional auto repair shop for regular maintenance.
