Experienced mechanics share their insights in answering this question :
Hello – both the overheating and the lack of heat out of the heater could be caused by inadequate bleeding of the cooling system when you put coolant in the car. To get all the air out of the system – with the radiator cap slightly loose – run the engine (fast idle) with the heater in the Max Heat position, fan on Max, until the engine has come up to operating temperature on the gauge, and air bubbles have stopped coming out of the radiator cap. If you still have overheating problems after properly bleeding the system, I would recommend an inspection of the cooling system by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

The most common reasons a Hyundai Accent is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat. Coolant leak (water pump, radiator, hose etc.)
Hyundai coolant temperature warning light
This light will come on when the engine is overheating. This could mean that coolant levels are running low, perhaps due to a leak in the system, or it could be a sign of a larger problem, like a head gasket failure.
Why is my car overheating but it has coolant in it? It could be that the coolant concentration is not correct, or you may have a bad thermostat, a failed water pump, broken drive belt, or a bad radiator or radiator fan.
Normal Temperature engine temperature gauge
Most experts agree that your engine should run between 195 degrees and 220 degrees.
If this light turns on, it means that your vehicle has detected that the coolant temperature is too high. This indicates that your engine is likely overheating. If your engine is overheating, it is recommended to pull your vehicle over to a safe place and turn off the engine for at least 20 minutes.
Technically speaking yes you can use plain water in your cooling system but it isn`t recommended as a long term solution and certainly not in extreme weather conditions.
Put your car in neutral or park and then rev the engine. This makes the fan and the water pump work faster, which pulls more air and more water through your car`s radiator. This increased circulation cools down the engine.
First of all, driving an overheated car can do more damage and make the problem worse. And secondly, even if your car does eventually cool down, it`s not necessarily safe to drive it. So, if your car ever does overheat, it`s best to pull over and call for a tow truck.
How long can a car overheat before damage occurs? It only takes 30-60 seconds of overheating for permanent damage to infiltrate a vehicle. As soon as you notice signs of overheating, you need to act. Failure to do so might result in troubles like coolant leaks, damaged radiator caps, and a faulty cooling fan.
Normal coolant temperature will be around 90°C (approx 195 to 220 Fahrenheit) and anything above or below this can start causing problems.
The average engine operating temperature lies between 75 to 105 degrees Celsius. Anything lower will make the fuel economy suffer and increase emissions, while a higher temperature will lead the engine to sustain damage.
There are four types of temperature sensors that are most commonly used in modern-day electronics: thermocouples, RTDs (resistance temperature detectors), thermistors, and semiconductor based integrated circuits (IC).
Can an engine survive overheating? Yes – as long as you respond quickly and don`t let your car go into full meltdown mode, it should be repairable. Too much heat can result in further complications, such as cracks leading to significant oil leaks or loss of performance.
The engine temperature warning light, which looks like a thermometer or simply the word “TEMP,” illuminates when your vehicle`s engine has exceeded the recommended maximum temperature. Because an overheated engine can result in major damage that`s often irreparable, you should take action right away.
As temperature of an engine exceeds 230 degrees Fahrenheit, the engine is overheated. Above 245 degrees Fahrenheit, damage may occur. As heat continues to increase, the different rates of thermal expansion cause metal to distort.
No, you should use distilled water or better yet, de-ionized water. The reason for this is that tap water has minerals that can deform deposits inside the radiator and the cooling system passages of your engine. And over a long period of time they can lead to over-heating.
Buying an antifreeze that requires you to mix it with water can be a little more involved. However, it gives you more flexibility when it comes to mixture. Generally speaking, a 50/50 mixture of water and antifreeze is a good place to start.
Nevertheless, oil (and any anti-wear components present in the oil) breaks down at high temperatures. Its chemical make-up becomes unstable, and it doesn`t absorb heat as readily. If you don`t change the oil consistently, you increase your engine`s chance of overheating.
May cause overheating. Also, a dirty air filter will not be able to provide the oxygen needed to provide a proper air-fuel mix. This can cause the temperature of your engine to rise to dangerous levels. Eventually, your vehicle`s engine could overheat which could lead you to the side of the road.
With the engine off, open your hood and locate the water pump pulley. With gloves on, grab it and wiggle it back and forth. There should be no movement, if there is, this along with the noise is a good indication you may have a water pump problem.
Standard thermostats: Enlist a friend or family member to assist, Position one person by the thermostat and one person by the furnace. Slowly turn the thermostat from off to heat and increase the temperature. Both the thermostat and furnace should make a sound.
One of the most common yet serious problems that develop in the cooling system is a radiator leak. A crack or leak from the radiator can lead to significant loss of coolant or antifreeze. Without these fluids present in the cooling system, air bubbles start to develop.
If the coolant tank is full, the problem may be electrical or mechanical in nature, in which case a tow to the nearest repair shop is definitely in order. A leaking hose, worn or broken fan belt, bad water pump, or malfunctioning thermostat may be the culprit.

My heat in my car stopped working two days ago and now my car is overheating. I put antifreeze in my car and it’s still overheating 2006 Pontiac Grand Prix
ANSWER : Hi there – you may have 2 related events here, a coolant leak, and a problem with the heater system. The current issue may be air inside the cooling system, which can cause overheating, and a lack of heater function. The lack of heater function could have 5 causes: the engine is not getting up to correct temperature (center of the gauge) due to a malfunctioning thermostat, the heater control valve is not letting hot coolant into the heater core, there is a restriction in the heater system that is preventing adequate hot coolant flow through the heater core, the heater fan is not working to transfer heat from the heater core to warm air for the passenger compartment, or the air blend doors inside the heater are not working properly to route warm air to the desired vents. I would recommend a heater system inspection](https://www.yourmechanic.com/services/heater-is-not-working-inspection) by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

car is overheating and leaking water and anti freeze
ANSWER : Coolant leaks can occur because of cracked hoses, leaking gaskets, faulty water pumps, or damaged radiators. When the coolant level goes low, the engine will start to overheat due to the low coolant level. I would first recommend giving the cooling system a visual look over. If it is not obvious where the coolant leak is coming from, I would recommed having the cooling system pressure tested in order to determine the leak source. If you would like to have your cooling system pressure testedcoolant is leaking inspection, consider YourMechanic, as a certified technician can come to your home or office to inspect your cooling system.

2003 hyundai accent it just passed smog like 4 days ago. yeaterday check egine light blinking and overheated but car not hot
ANSWER : Hello, thank you for writing in. Overheating the engine is one of the worst things that can happen to the vehicle, and you want to do your best to stop the vehicle before it gets to that point. Running the heater may also help decrease the temperature. The cause of the overheating may be related to the noise coming from the exhaust. If the exhaust system is clogged, your engine will overheat and stall. With the check engine light on, you will want to have three vehicle scanned for diagnostic codes. Use these codes to help point you in the right direction. Other possibilities may include a failed head gasket, issue with the cooling system, and other similar faults. For more help with diagnostics and resolving the problem, contact our service department to schedule an appointment.

Replaced alternator on car 2 times each time shows it’s charging 14v let car run for a little bit then test drive and car voltage
ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.

My car overheated while on the highway. I added coolant and let the engine rest and cool down. Now the car will not start. How can
ANSWER : Hi there:
Unfortunately, there is no exact reason we can offer to you as to why the vehicle won’t start now after your overheating issue; without first inspecting the vehicle. However, if the vehicle overheated on the highway there is a high possibility that major engine damage has occurred, which is possibly why the vehicle won’t start now. This damage could include head gaskets being blown, which can cause coolant to enter the internal portions of the engine and lead to additional damage. The best thing for you to do is have your vehicle towed back home, then contact YourMechanic.com to have one of our professional mechanics complete a car is overheating inspection.

My car will not start Intermittently. I purchased a new battery 2 weeks ago and yesterday the car wouldn’t start. Got a jump and
ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
