What can I do to stop my engine from overheating?
Even though you may enjoy the summer’s heat, you must help your car stay cool when the mercury rises. Overheated engines can harm the car and endanger your safety. Here are some suggestions we’ve put together to help you avoid having an overheated car.
Put your car in a shaded area.
In addition to keeping you cool, parking in the shade can increase the lifespan of your vehicle. No shaded area? To lower the temperature inside the car, use a sunshade.
Utilize automobile window coverings
UV heat shields will prevent the inside from becoming excessively heated and will shield it from the sun’s harmful rays.
window tinting
Window tinting or window film can be applied by a nearby dealership or auto body shop to help keep your car cooler and offer UV protection against sun damage.
Keep the automobile windows slightly open.
Keep your windows slightly ajar and, if you have a sunroof, crack it open as well.
Activate the floor vents.
Because hot air rises, switch to the bottom vents and turn your blower all the way up to get rid of that air. You can then reopen the upper vents once the car has finished cooling down.
Use your air conditioner’s fresh air setting rather than recirculation.
Recirculation is something you want to employ after your automobile has had a chance to cool down since it simply moves that hot, trapped air around your vehicle.
Keep an eye on the car’s thermometer.
The instrument features a needle that should always be aimed in the direction of the middle. Pull over, turn off the engine, and let the car cool down if it seems to be getting hot.
To cool the engine, turn on the heat.
On a scorching summer day, turning on the heat may be the last thing you want to do, but it can cool the engine by drawing hot air from the engine compartment.
Boost the engine coolant
On the reservoir, indication lines on the coolant level are displayed. Simply add the necessary amount of coolant if it is too low, then reconnect the cap. To a hot engine, never add coolant.
Have a mechanic flush your radiator
In a radiator flush, also known as a coolant flush, the radiator’s old coolant is drained, it is cleaned with flush fluid, and then new coolant is added.
Think about getting a new automobile battery.
If your car battery is more than three years old, it might not be supplying as much power, causing your engine to work harder and potentially overheating.
Even if you enjoy the summer’s heat, you must help your car stay cool when the mercury rises. Overheated engines can harm the car and endanger your safety. We’ve put together the following advice to assist you keep your automobile from overheating:
Turn on the heater.
Reina advises turning on the heating, even though it seems counterproductive. It relieves pressure on the engine’s cooling system by transferring heat from the engine to the passenger area. That might be sufficient in some cases to stop the overheating, according to him. If the warning light shuts off or the temperature gauge returns to neutral, you’ll know it’s working.
Pull over.
The safest and most reliable approach to cool the engine, according to Reina, is to pull over and turn off the engine if your car continues to overheat after a few minutes of driving with the heater on. Reina advises you to call roadside assistance right away if you have it because you might need a tow.
Sit tight.
Be patient if you don’t have roadside assistance; the engine will need at least 15 minutes to cool. In the interim, Reina advises against attempting to open the hood because an overheated car’s coolant might be over 230 degrees. You run the risk of getting splashed with hot water or steam once the hood is opened. “The most crucial thing is your own safety, he continues. “The engine, hood, and any leaking coolant can cool down by waiting for at least 15 minutes.
Add coolant.
Put on gloves, open the hood, and locate the radiator cap after waiting at least 15 minutes and the hood is cool to the touch, advises Reina. If necessary, refer to the owner’s manual. To relieve pressure that has built up due to the coolant expanding when heated, cover the cap with a towel and carefully push down and loosen it a quarter turn. When the liquid reaches the radiator, fully open the radiator cap and gradually inject coolant (half water, half antifreeze) “entire line. The little, transparent plastic overflow reservoir located on the side of the radiator should also be filled with coolant, he advises. After that, put the cap back on and start the engine. “According to Reina, you can move forward with caution while keeping an eye on the temperature gauge or light if the red warning light or temperature gauge returns to normal.
Drive to a service station.
Although adding coolant doesn’t fix the issue that initially caused your engine to overheat, it frequently enables you to travel safely to the closest repair facility. “Your car’s cooling system needs to be examined by a specialist, according to Reina. Keep an eye on the thermometer while driving. And pay attention to everything, including any fluid or steam under the automobile “According to Reina, the diagnosis will be substantially aided by this fundamental information.

Which are the top 10 typical causes of overheating?
The engine of a car can overheat for many different causes. Filling up your antifreeze reservoir, for instance, could be a quicker cure, but if other problems are not correctly handled by an expert, they might require more extensive repairs.
The following are typical causes of car overheating:
Too little or no coolant
A coolant system failure could result from driving without the right amount of coolant or antifreeze. Refill or top off the coolant/antifreeze levels if they fall below the manufacturer’s recommended level. Use only a 50/50 mixture of antifreeze/coolant and water when adding new coolant to an empty reservoir. Consult your car owner’s manual if you’re unsure of where the coolant reservoir tank is or how to properly fill it.
Cooling system leaks
A possible leak can be the reason for the coolant reservoir tank being empty. Spots or pools on the ground are frequently signs of coolant leaks.
Be advised that depending on the type of coolant being used, it may have a nice scent and be green, blue, or orange in color.
A broken water pump
The coolant must be moved around the engine by the water pump. It can prevent coolant from flowing through the pump if the coolant is contaminated or has too much buildup, which can result in an overheating problem.
Radiator issues
By lowering coolant temperatures, radiators and their fans contribute to the reduction of engine heat. Problems with the fans might make the radiator less effective in removing heat, which would lead to unnatural temperature spikes.
Thermostat failure
The thermostat in a car is necessary to control engine temperatures, just as the thermostat in a home. When a thermostat malfunctions, the engine may suffer because the coolant cannot flow as the car’s manufacturer intended.
Issues with the belts and hoses
The ability of the coolant hoses and belts to sustain the flow of air and coolant to and from the engine and related components would be compromised, which could result in unforeseen engine damage. View our services for Belts & Hoses for more details.
Can my automobile be driven after it has overheated?
Your vehicle can be protected with the appropriate auto insurance. These common sense advice can help if your automobile overheats.
- Locate a secure spot to stop. It’s advisable to cease driving as soon as you can because continuing to do so might seriously harm your engine, sometimes permanently. Turn off the engine after stopping and moving out of the way of incoming traffic.
- You need add coolant. If you can’t locate a leak, your coolant level may be low. Follow these suggestions from Consumer Reports for a quick remedy if you are comfortable and confident in your ability to identify the correct parts of your engine. You must unscrew the radiator cap in order to check the coolant level, but only after the engine has cooled. Using a towel, slowly remove the cap after your engine has had time to cool. The radiator’s top should be covered with coolant. If it doesn’t, add more ice. Also, if your car has one, make sure to inspect the plastic coolant expansion tank. The majority of automobiles use a 50/50 mixture of water and antifreeze, but a quick repair is to simply add room temperature water.
- Search for leaks. Even if you’re not a technician, some cooling system problems are simple to spot. To check for coolant leaks, inspect your radiator and hoses.
- Open the hood (or call for help). After you’ve parked, open your hood to let out any excess heat, then hang back to allow the area cool. Remember to exercise utmost caution because a heated engine may suddenly erupt with steam or boiling coolant. It’s okay to ask for assistance if you don’t feel confident doing it on your own. In either case, never use bare hands to touch a hot engine!
- Increase the heat. Although you might be tempted, it makes no sense to put on the air conditioner. The heat produced by your engine can be dispersed more effectively by turning your heat up to maximum.
- understanding when to call a mechanic If your car’s coolant level was low, topping it off will allow you to restart it. Make sure your thermometer is reading within a safe range by keeping a close check on it. You should contact your repair right away if you discovered a coolant leak or noticed that your coolant reservoir was full.
Reason#1Engine Coolant Is Low
Almost all of the meaning of coolant is contained in its name. In order to prevent overheating, it keeps your car cool. Thankfully, you might only need to add more if you’re running out.
The coolant in your automobile is likely full if it is overheating, thus there is probably no leak. Instead, it might be having problems properly circulating. A malfunctioning water pump, a clogged radiator, a jammed thermostat, or a plugged heater core are just a few causes of this.
Reason#2Water Pump Is Failing
The water pump’s job is to circulate coolant from the radiator through the remainder of the cooling system. As you might have imagined, if your engine doesn’t get enough coolant because your water pump is malfunctioning, it could overheat.
Reason#3Radiator Has A Blockage
Radiator coolant absorbs and disperses heat as it circulates through the radiator. The coolant might not be able to flow through if it is damaged or if something has gotten stuck in it.
Fortunately, the radiator is quite simple to visually inspect due to its location close to the front of the car. Remove whatever debris you see. But regrettably, if it’s broken, replacement is often your only choice.
Reason#4Thermostat Is Stuck
Controlling how much coolant flows through the cooling system is the thermostat’s responsibility. It won’t be able to do so correctly if it is stuck for whatever reason. It goes without saying that if this part isn’t functioning properly, your engine could overheat.
