In 2012, the movie, Curtis struggles to get on a plane with his family as his car melts and splits into pieces while the earth beneath him rips apart.

In 2025 too, doomsday is not far if you’re stranded in the heat for long – just because your car gave up.

Summer heat can be harsh - not just on you but also for your car. Higher temperatures strain your vehicle’s engine, be it a hatchback, a sedan, or an SUV, resulting in the car overheating in the summer, breakdowns, and expensive trips to the mechanic. If you've ever had to pull over to the shoulder of the road with steam pouring out of the hood, you know how irritating an overheating car is.

The reasons behind your overheating car during the summers

Your car engine usually runs hot. Summer can increase the pressure on your radiator cooling system. Below are some common causes for car overheating in the summer.

1. Low Level of Coolant: Antifreeze (coolant) plays a major role in maintaining an engine at a reasonably lower or higher temperature. Car coolant levels may drop in summer due to evaporation, increased engine heat, leaks in hoses due to expansion, or cooling system issues. If the antifreeze goes too low, the antifreeze will hardly absorb and give off heat from the engine, resulting in increased engine temperature, and then only a car service centre will be able to rescue you.
2. Stuck Thermostat: The thermostat is responsible for regulating the coolant flow between the engine and the radiator. High temperatures can cause heat buildup, thus damaging the thermostat, causing it to get stuck in the open position or closed position. If the thermostat is stuck shut, it will block the flow of coolant, the cooling system will fail, and you’ll need to rush to the nearest car service provider in Mumbai.
3. Radiator Complications: A clogged, damaged, or leaking radiator can no longer dissipate heat consistently. Dirt, grime, and rust build up to block air circulation, increasing the chance that the motor will run too hot. If you're in Mumbai, look for radiator repair services in Mumbai for expert solutions.
4. Cooling Fan Failure: Electric cooling fans pull air through the radiator. The cooling fan could give way in summer due to a blown fuse, wiring problem, bad motor, coolant leaks or motor overheating. The radiator won't be able to cool the engine efficiently, and the heat will get the best of you.

Ways to Prevent Your Car's Engine from Overheating on a Hot Summer Day

Now that you are familiar with the causes, it would be time to tackle the ways of preventing overheating of your car in hot weather conditions.

1. Check The Coolant Levels For Your Car Maintenance: Before summer comes charging in with all its heat, check whether your vehicle has topped off on coolant. Make sure to use the prescribed coolant for your hatchback or sedan here. Help someone by checking under the vehicle and around the radiator for leaks.
2. Check and Replace Thermostat if Necessary: If your car frequently overheats, the culprit is most likely a bad thermostat. Have this checked by a mechanic, and if necessary, replace it.
3. Clean the Radiator and Maintain it: Flush the radiator now and again to remove rust and debris. The radiator cap should seal thoroughly and should maintain pressure. Visit a trustworthy car service center if you require radiator repair in Mumbai.
4. Proper Mechanical Working of Cooling Fan: Condition in which the engine heats up even with the fan running; if not, it means it has failed. Get expert help from a car service center in Mumbai to inspect the fan motor, fuse, and wiring.
5. Keep an Eye on the Water Pump: Failure in the water pump would cast the cooling system dead, so check it out when it's serviced. It may be a replacement issue if the coolant is leaking near the water pump.
6. Maintain the Engine Oil: Oil check on the engine regularly and make sure to top up when needed. Have some premium engine oil in case of overheating, fix for a hatchback/sedan engine.
7. Drive Smart to Avoid Heat Buildup: Do not drive aggressively, especially when you are in hot weather. The weight of the car strains the engine when overloaded. Temperature reduction might happen if you shift to neutral when stalled in traffic.
8. Park in the Shade and Use Sunshades: Directly sun-parking adds to a smaller internal temperature of the car, putting the car at risk of overheating. A sunshade or windshield cover would help keep the car's interior cool.
9. Switch Off Air Conditioning If Your Car Is Overheating: In case of an engine temp spike, switch off the air conditioner and lessen the load. Then, blast that heater to help an engine dissipate heat.
10. Get Regular Auto Servicing: It prevents your car from overheating during the summer, as well as every other season of the year. Before the onset of the summer season, you could book a full inspection at one of the trusted multi-brand car services in Mumbai
