Inspect The Radiator Cap
As part of your general vehicle maintenance, check the radiator caps quality as well. The radiator cap is so crucial in preventing overheating. It keeps the pressure steady for the whole cooling system to stop fluids from boiling. Because of its nature as a spring-loaded component, it weakens over time. It may result to air leaks. This decreases the systems pressure, leading to an overheated engine.
What Are The Effects Of Driving Overheated Engine
When your cars engine run with an abnormally high temperature, these are some of the possible effects:
- Thinning of engine oil which may result to inefficient lubrication.
- When oil becomes thinner, it may affect the engine block, cylinder head, and other running internal parts.
- Thinning of oil lets a very minute insulation between running parts on the engine that will cause friction. Metal to metal contact on engine parts is highly damaging to these components.
Hybrid And Electric Vehicle Batteries
Not long after the Tesla Model S was awarded the unofficial title of “the safest car ever” by the media , a Tesla Model S caught fire in the fall of 2013. That’s never good, of course, but for Tesla, it was especially bad. The company had implied numerous times that its fully electric Model S was all but immune to the battery-related problems that have plagued hybrid cars and EVs of the past. Alas, a Model S traveling at high speeds hit a piece of debris that punctured the car’s battery, and the battery behaved like any other battery would: it ignited. Several other Teslas have caught fire since the first one in 2013, though these types of fires are rare.
Chevrolet recalled about 110,000 of its Volt EV model years 2017 to 2022 for potential battery fire issues. The problem was traced to a hardware and software issue in the batteries. It’s estimated that about one-third of fires in electric vehicles occur while the car is parked and unplugged.
But hybrid cars seem to be the most likely to catch fire, with gasoline vehicles coming in second. Cars that run only on electricity are a distant third. Of course, because there are more gasoline-powered cars on the road, they also account for the vast majority of total fires.

What Are The Reasons Why Car Wont Start When Engine Is Hot
The faulty fuel system in your car is the most common reason why your car wont start when the engine is hot. There are still many reasons why car wont start when hot, such as the coolant level in your car, car battery, etc. If these issues are not detected in your car, your car has a deeper problem with your engine.
Here is some very potential reason why your car wont start when hot :
You must know that there can be many reasons why cars get hot, whether its for outside weather or internal car issues. Keeping the car engine clean and proper maintenance is the key to avoid car overheating issues. These potential reasons are applicable for any types of causes why your car wont start when hot.
What Does Hot Weather Do To Your Car
Summers are getting hotter in the UK, with temperatures regularly hitting 30°C. While this is great news for beach-goers and kids on their six-week summer break, it isnt ideal for our cars which can be affected by the heat.
Breakdown statistics show that theres a 20% increase in roadside callouts when its hot, rising to 30% in coastal areas. Cars are also 50% more likely to overheat in warm weather, which is one of the leading causes of breakdowns on UK roads.
Despite modern cars being built to withstand extreme changes in temperature, prolonged exposure to either freezing or sweltering conditions always has the potential to cause some problems. In the height of summer, when cars have to work in hot, dry conditions for weeks at a time, this can impact on performance and safety so its important to keep on top of their maintenance and upkeep.
But what exactly does hot weather do to your car, and how can you prevent damage and performance problems? In this guide, we look at the impact heat can have on cars, and what can be done about it.

How Do I Know If My Engine Is Overheating
Other than smoke popping from the hood and the hood being unusually hot, other signs can tell you your car is overheating include:
- The temperature gauge reading near maximum or the gauge light flashing on.
- A distinctive burning smell caused by melting of bits of resin holding the engine together like plastic valves and rubber seals.
- Thumping sounds.
- Hearing a ticking noise from the engine.
- Steam billowing out from under the hood.
- Coolant leaking under your car.
During overheating, the pistons powering your vehicle can get bigger and seize in the cylinder bore. If you continue to run the engine when it’s in such a dangerous condition, you may end up cracking the cylinder heads and engine block, which will lead to a costly intervention from the mechanic.
Vapor Lock In The Fuel
Vapor lock might be a potential reason If you notice that your car is hard to start when the engine is hot. When your car fuel boils in the fuel line and the vaporized fuel creates back pressure in the car fuel system, which prevents the gas from going into the engine. If your car has been idling or turned off and then back on, this can bring you vapor lock issues in your Car.
When your car fuel boils in the fuel line and the vaporized fuel creates back pressure Vapor lock can happen for another reason: clogged vent lines. If your car vent line is blocked, the vapor will mix with fuel to rush out of the tank, which will cause engine performance issues and make your car struggle to start when hot.
Symptoms of vapor lock in cars :
- Loss of power .
- No starting.
- Loss of fuel pressure.
- Engine Stalling.
Vapor lock issues are mostly related to your car starting. Thats why you should check the vapor lock in your car with an auto mechanic if the car wont start when engine is hot.

What Causes A Car To Overheat In Stop
An overheating engine is a big problem. Engines that run too hot are at risk of complete destruction, as the engine block itself can warp when there’s too much heat. When engines overheat, it generally happens at any speed however, there are times when the engine will be fine at speed and only begin to get too hot when the vehicle is idling in stop-and-go traffic.
No matter what’s causing your vehicle’s engine to overheat, we recommend pulling over and shutting off the engine as soon as it’s safe to do so. If the needle in the temperature gauge only started creeping into the red when you were in traffic, let the technician who looks at your Subaru know that will likely narrow it down to one of these three things:
Wrong Charger / Incorrect Charger Settings
Choosing the incorrect charger for the job or having the incorrect settings on a charger can lead to costly mistakes by damaging or destroying your battery and by possibly causing it to explode, leak or cause a fire.
First, we want to steer clear of any charger above 10 amps to be safe when charging a car battery. I prefer to stay at 6 or under, as it leads to a slower but more complete charge anyway and maximizes the amps the battery is able to absorb.
A car battery will generally have an amp-hour equivalency between 50 and 80. The rule of thumb is to keep your charging amps at 10% or less of the total AH capacity of a battery. The other rule of thumb is that it if you have a 10 amp charger, it will replace about 10AH in the battery per hour.
If you use a battery charger with a 50 amp rating, youre essentially trying to fill the entire battery in one hours time! While a speed charge sounds nice for getting you on the road sooner, it places an enormous amount of strain on your battery.
When being charged, the battery is converting electrical energy into chemical energy but it can only do so at a certain rate, and that rate changes based on the increasing charge of the battery. The more charged it becomes, the slower it charges as it cannot convert as quickly.
If you couldnt get the water down fast enough youd throw up. Your car battery, on the other hand, has to do something with the excess electrical energy that it is receiving but that it cannot convert.

Top 10 Causes Of Car Fires
There’s rarely a single cause for any given car fire, even if an investigator can trace all the way back to the incident that sparked the blaze. What’s more likely is that it was caused by a combination of things: human error, mechanical issues and chemical sources. And these may have all worked together to create a fire.
In other words, once a vehicle’s on fire, any number of additional factors can complicate things. Knowing what those factors are can potentially help you avoid a dangerous situation.
The most important thing to remember is that once a vehicle is ablaze, it really doesn’t matter what caused it. Don’t worry about whether the engine was overheating or what fluid you might have spilled . If your car is on fire, get out fast and get as far away from the car as possible.
A small car fire isn’t going to stay small for long, and any combination of the initial causes we’ll discuss in this article will quickly make the situation much, much worse.
Inspect The Coolant Tank
If you are all for DIY work, wait for the engine to cool down before you check the tank containing coolant. The coolant tank is made of a plastic, translucent material. It is near the radiator. If it is still full, the issue is either mechanical or electrical such as malfunctions related to the thermostat, water pump, fan belt, and hose. Let the pros fix it.
However, once you spot that it is empty, it is very possible that there is a leak. Immediately look under the car. If there is a puddle or drip, make sure to do the next step.

Alternator Or Voltage Regulator
This runs in the same vein as having an incorrect charger or one on the wrong settings.
After you turn your cars key, the battery releases a short but high amperage to start up the engine and electronics of your vehicle. Immediately thereafter, the alternator is engaged and converts mechanical energy into electricity.
The voltage regulator is responsible for taking the electricity from your alternator and making it suitable for the battery to absorb.
If either of these malfunctions, your car battery could easily overheat from being overcharged or by failing to charge which will lead to the battery discharging at a high rate which will also lead to overheating.
Thermostat Is Stuck Shut
The most common symptom of a failed thermostat is overheating at highway speeds. Your engine may be able to stay cool at low speeds because it’s not working that hard, and therefore not creating as much heat. When you hit highway speeds, however, your engine needs a lot of coolant flowing through to keep it cool.
If the thermostat doesn’t open, there isn’t enough flow to keep things cool. In this situation, you may find yourself looking more like a steamship than a sedan going down the highway.

Engine Oil Type Expansions
Synthetic oil has a higher rate of expansion and contraction with temperature changes. These blends will be much tighter when cold and could expand even more than expected when hot.
Regular oil will experience normal expansion and contraction, which means you will get around the same readings regardless of temperature.
Newer cars with electronic oil level controllers will only measure the engine oil when warm and stay at a flat surface level. Therefore its recommended to check the engine oil when the engine oil is hot.
Check your repair manual for the correct oil measurement of your car.
Cooling Fan Belt Break
For vehicles with a longitudinally mounted engine, the fan can be driven by a drive belt from the crankshaft pulley. In this case, the fan runs forcibly. Resource drive belt from 30 to 120 thousand km. Usually, several nodes are driven by a single belt. When the belt breaks, the internal combustion engine instantly tends to overheat, especially when the speed is reduced. If you have a domestic car with a belt fan drive, it is recommended to install an additional electric fan in order to avoid unpleasant cases.

Normal Engine Temperature In Winter
Before you start driving in winter after a long period of inactivity, you must let the engine run at high speeds for no longer than 7 minutes, and at low speeds for no longer than 5 minutes. After that, you can start moving. With a working cooling system, the engine will have time to reach operating temperature during this time.
In winter, during frosts, the operating temperature of the internal combustion engine is about 80-90 degrees. In order for the engine to adequately reach this indicator, there must be a suitable antifreeze or antifreeze in the cooling system, but in no case water. The reason is that water freezes at -3 degrees. During crystallization, the ice will surely break the water jacket of the motor, because of which the power unit will have to be changed.
Child Heatstroke Deaths Over Time
Parents strap their toddlers in their car seats, they fall asleep, and the parents forget that they are even there. Being in the backseat is definitely the safest place for children, especially in the event of a car crash, so parents must be vigilant to keep an eye on their kids and not leave them in the car alone.
As you can see, dozens of children die each year after being left in a car for too long. On average, 37 children die each year from vehicular heatstroke. This means we are well on our way to contributing to the average again this year.
Leaving a child in a car is dangerous, no matter the time of year or length of parental absence.
