The radiator is an important component of the temperature regulation of the car. On how to stop a car from overheating while driving, you need to hydrate the radiator by adding a bit of coolant and water.

Do not under-fill or overfill to prevent overheating. If the car is already overheating, be careful while loosening the cap as heat pressure may cause the leftover water/coolant to spill.

2. Rev Your Car

Does revving help the engine from overheating? To an extent, it does. Subtly rev the engine of your vehicle before driving.

It helps to better vibrate some components in the car and support seamless oil movement throughout the engine. It is not the best practice on how to stop a car from overheating while driving an already heated car. Do not rev the engine if it is already overheating.

3. Leave the Windows Slightly Open

If you are certain that the car you are driving will overheat, do not fully close the windows. It should save as a natural coolant from the inside out of the vehicle.

When the car is parked, you may then close the windows for safety reasons. However, it is a poor practice to keep driving an overheated car while depending on wound down windows.

4. Leave Open the Engine Hood

If the car is already overheating, take a break from the ride for at least 20 minutes while leaving the engine hood open. You may extend the action to the trunk but it does not matter since the trunk houses no engine. Upon opening the engine hood, do not pour water on the engine as it may instigate the heat.

5. Disable the Air Conditioning

how long can you drive a car while overheating

Can air conditioners cause a car to overheat? Yes, it can. It is either a failed air conditioning compressor that increases the engine load or the compressor locks up on the fan belt which makes it difficult for the fan belt to cool the heat from the engine coolant. So, disable the air conditioning when the weather condition is friendly. This will help to subdue pressure on the engine and cool the car.

6. Consider Replacing the Battery

Can a bad car battery cause overheat? A faulty battery can cause overheating while driving. If your battery is older than 3 years, you should consider a replacement. Better still, let the mechanic inspect the condition of the battery to determine how dependable it is for the car.

In cases where the battery is old, it might require replacement but this is left for the mechanic to decide. As an intelligent practice on how to stop a car from overheating while driving, do not cruise around with a faulty battery.

7. Park Under Shades

Do not expose the car to overly hot weather.

Park near shaded zones and be mindful of what lies next to the car. Some of the structures along the road or in the house may not be harmful when near the car. Furthermore, it is perfectly what to do when a car overheats and won’t start.

What Causes Overheating in a Car?

Low Level of Coolant

Does low coolant level cause a car to overheat? Yes, once the coolant level is low, it results in overheating. The heat that should have been disposed of from the engine would be forced to remain while the coolant continues to steam.

To perfectly practice how to stop a car from overheating while driving, halt the ride, and fix the coolant level. Hey, low coolant while a car is overheating may damage the engine.

Worn Thermostat

The thermostat helps to regulate the flow of coolant. However, a broken thermostat will cease to perform this function which prevents the radiator from receiving coolant from the engine. Wondering what the thermostat is? Check between the engine and the radiator of your car, you should find the small device.

Leaky Water Pump

A leaky water pump prevents coolant from moving through the engine block, hose as well as a radiator. Where there is a leakage, coolant ceases to go through which results in a rapid temperature rise. This could be the reason why your car is overheating but the engineer will decide that.

Damaged Radiator

A damaged or crack radiator is another of the lethal reasons why a car overheats. The engine will be unable to receive an appropriate share of the coolant when the radiator is cracked. In cases where the crack is completely broken, replace it and do not take such a car out on the road.

Low Oil Level

Motor oil is vital for keeping the car temperate. When the oil level is low, the engine is unable to flush its waste heat which results in overheating. Ensure there is moderate and thick motor oil available to provide your car a seamless performance.

Broken Cooling Fan or Fan Belt

The radiator fan or cooling fan sits between the radiator and the engine. It moves cooling air through the radiator while your vehicle is parked or moving at a slower pace. While the cooling fan is active, it absorbs heat from the engine-made coolant to keep the temperature at a moderate level.

If broken, you can be certain that the heat in the coolant made by the engine will not be removed, thus, causing overheating. The radiator fan belt also called serpentine plays a huge role by linking the alternator and crankshaft pulley to the cooling fan. If broken, it can result in your car overheating.

The Weather Condition

So, how do you fix a car that overheats under a bad weather condition? Simply park in a shade or don’t drive at all. If you are tempted to drive, schedule the ride for early mornings and evenings.

Broken Hose

One of the car hoses connects the radiator to your car. When it is broken, it is obvious that there is no longer a channel for coolant passage which results in overheating.

Why Is My Car Overheating but It Has Coolant in It?

When the engine coolant is not circulated, it becomes difficult for heat to be discharged. This forces the radiator to heat up, thus, resulting in overheating. You have either a faulty hose, poor thermostat, or damaged water pump.
