It doesn’t matter what kind of car you drive; if the weather is really hot, there’s a good chance that your automobile may overheat. The first symptom of a problem will be that the temperature gauge indicator on your vehicle will begin to climb, and in many cases, you will also notice that your engine is beginning to steam up or smoke.
If you have been pondering “why is my car smoking under the hood and overheating”, the two sections covered below will help you out.
Things to Do When Car is Overheating
Turn On Your Car’s Heater and Turn Off the Air Conditioner
Because of this, the energy will not be sent into your engine. When the temperature is already high, you should be sure to open the car windows. If this doesn’t work, and you see that the temperature is continuing to rise, pull over to a safe location and switch off your engine when doing so is safe. If you continue driving even while the temperature is rising, you might end up causing harm to your engine. Please get in touch with an auto mechanic as possible if you think you are in need of a fix!
Turn Off the Engine and Open the Hood
Open the hood of the automobile if you can do so. Do not open the hood until your car’s engine has had sufficient time to cool down. Only proceed with this if you are certain that it won’t put you in harm’s way. In the event that you have no clue why your vehicle may have overheated or what to do, it is imperative that you contact roadside help as soon as possible.
Check the Coolant Level
It’s possible that you have a leak if the coolant levels in your vehicle are low or totally gone. Put in a call to the roadside help service right away. If the coolant levels are within the typical range for the capacity of the system, the problem may lie in the temperature gauge. If this is the case, you will need to wait until the engine has totally cooled down. You are free to go to your destination; however, you should use extreme caution. Immediately after you notice it, swap it out for a brand new thermostat gauge. During the course of your vehicle’s inspection, it is best practice to have the coolant levels checked and filled up as necessary.
If You Have to Drive the Car Anyway Wait For the Car’s Engine to Cool Down
To remove the radiator cap, use a cloth or glove and twist it off. It is essential that the radiator, as well as the reservoir, be refilled with coolant. You may make use of water if doing so is absolutely required.
This is by no means a solution that will hold up over time. Because of this, your engine will stay cool for the short amount of time necessary for you to reach the destination. In the event that you observe that the temperature is once again rising, you will be required to pull over and carry out these steps once more.
Make sure to take your vehicle to the mechanic as soon as possible, preferably before the problem develops into one that requires more expensive repairs.
Things to Do If Your Car is Smoking Under the Hood
Even if there is smoke coming from below the hood, this does not automatically indicate that there is a fire. In the case of automobiles, the proverb “where there’s smoke, there’s fire” is not applicable. Sometimes automobiles simply smoke. However, smoke coming from below the hood is often an indicator that something is not functioning as it should be.
If the smoke is coming from below the hood of the vehicle and smells like tar or asphalt, then it is most likely oil that is burning. If the oil is leaking out of the system and dripping onto different components of the automobile’s engine, then it will eventually burn off.
In addition, the oil may occasionally find its way into the fuel system or the engine, where it will catch fire while the engine is operating. This occurs whenever a gasket develops a leak. If you see that your oil level is decreasing or that it is burning away, you should have the oil system checked out as soon as possible.
If it is really the oil that is catching fire, then you will need to have all of the gaskets changed. This is due to the fact that over time, the engine will be damaged by the burning oil.
In addition, you do not want the oil to burn, as this might result in you driving with insufficient oil, which will result in very high maintenance costs and could possibly cause your engine to blow up.
It won’t cost you very much to have the seals and gaskets changed in order to stop the oil from burning, and doing so will end up saving you money in the long term since you won’t have to deal with more serious damages or continually top up your oil supply.
Smoke comes from Filler Cap
The filler cap generates a different kind of oil smoke as well. This is particularly relevant when the age of your vehicle increases. There is a buildup of residue, and when the engine reaches operating temperature, the residue will burn off.
This also happens if the valves that are located within the piston cylinders have become worn. It is possible that you will need to replace the seals in order to maintain the oil in the correct location.
Clogged PCV valves or tubes are another source of smoke coming from the filler cap; hence, if you have this sort of smoke coming from the filler cap, you must get those components examined as well.
The electrical system is the very least likely place that smoke may be coming from. Because the majority of the wires in the vehicle are sheathed and insulated, this scenario does not occur very often.
The alternator is one component of the electrical system that may produce smoke if there is a problem beneath the hood. There is a possibility that the alternator may begin to fail and short out. This can result in a few puffs of white smoke. If the alternator is malfunctioning, the vehicle should display a check engine light as well as a low voltage light. If the smoke comes from the alternator, then you should be able to figure out the problem rather quickly.
Other than the automobile overheating, you are now aware of what to do when car overheats and smokes. You are also aware that the hue of the smoke and the smell may be useful indicators of what aspects of the system need to be examined.
Smoke that is black and sooty indicates that there are problems with the vehicle’s fuel system, chemical smoke that is white or gray in color indicates that you need to check the vehicle’s power steering, and transmission and blue smoke indicate that you need to check the vehicle’s oil system.
Because now you have the answer to your query “why is my car smoking under the hood and overheating”, you will be able to act appropriately the next time your vehicle smokes for a reason other than it being overheated.
