Car overheated and battery light came on, now car won’t start.

I was driving to work and heard a sound like gravel being turned for about 20-30 seconds. Shortly after that my battery light came on and the temperature of the engine started to go up very quickly. The clock and heat went out as well, though the headlights and radio stayed on. I checked under the hood after I got to work and the vehicle had time to cool off. The coolant top had popped off and all the coolant was gone. I went to to start my car later and it wouldn't turn on, however, the battery light was still on.
Experienced mechanics share their insights in answering this question :
It sounds like you have had a failure of one of the belt driven accessories under your hood. The pulleys attached to you engine have bearing in them so they can spin freely. When one of these bearings fail you can hear a sound of gravel being turned as you described. It is then possible that the belt could be damaged to the point where it slips off or breaks. This will cause your water pump to stop circulating coolant in your engine which could cause it to overheat and blow off your radiator cap. It will cause your alternator to stop charging your battery so you could lose electrical power and turn the battery light on. I would ask for help from a mechanic to check your serpentine belt system for any issues and make the necessary repairs.

Likely your belt that drives the alternator and water pump has snapped. Pull over and check. Overheating will damage the engine.
Overcharged batteries: High temperatures can also lead to battery overcharging. While it might sound like a good thing, the overcharging process can cause overheating and other issues that lead to premature battery failure.
The optimal temperature for a car battery is 80 degrees F, and whenever it exceeds that temperature, internal corrosion can occur. Additionally, hot weather can cause your battery acid to evaporate much quicker. The decline in acid can deteriorate the functionality of the battery, leading to the need for a replacement.
This will cause your water pump to stop circulating coolant in your engine which could cause it to overheat and blow off your radiator cap. It will cause your alternator to stop charging your battery so you could lose electrical power and turn the battery light on.
If batteries are exposed to excessive temperature, they will stop working, bulge, bubble, create sparks and flames, damage your device, or blowup. Extreme heat can lead to battery corrosion that shortens the average car battery life.
When your coolant is running low, the engine can overheat or even seize up. If the metal gets hot enough, a piston can weld itself into the cylinder. If this happens, your engine is likely destroyed.
An overheating engine won`t resolve on its own, even if it seems to be fixed after you add a little coolant. It will only get worse if left unaddressed.
Overheating can damage many engine components such as the thermostat, crankshaft position sensor, and so forth. Overheating does damage alternators but the overheating in alternators is typically caused by electrical overloads, that is too much current flowing through the alternator.
Repeated overheating can be a sign of serious engine damage. Repeated use of an overheated engine can accelerate that damage rapidly. In extreme heat, core parts of the vehicle`s engine can crack, warp, and fail — resulting in instant death to your vehicle`s powerplant.
When coolant is low, your engine will start to heat up. The feature will automatically shut off the engine to prevent damaging the engine. Once your engine cools down, you will be able to drive your car again.
A bad battery can cause problems in electrical and electronic parts, including the computer. It can even cause a “Check Engine” light. Next, test the alternator and pay close attention to the condition of its diodes.
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.
If your battery gets very hot, though, it may indicate that your charging system has some problems. On a weak battery the alternator may be working harder than normal to keep it charged. This constant charging will cause the battery to heat up. A faulty alternator can also cause the battery to heat up as well.
What Is Thermal Runaway? Put in the simplest of terms, thermal runaway in lithium-ion batteries is an overheating of the battery cell which results in a chemical reaction.
That said, a severely overheating engine can cause the cylinder walls or the pistons themselves to warp, bend and deform. This will cause the perfect seal between the piston and the rest of the engine to lose integrity. Oil could be forced past the piston rings and into the engine, where it will burn the oil.
OVERCHARGING A LEAD ACID BATTERY

At high rates of overcharge a battery will progressively heat up. As it gets hotter, it will accept more current, heating up even further.

Symptoms of a burnt out diode:

The engine will begin to run rough, lack power and eventually stall and not start again. The battery warning light will turn on, warning you that there is a problem with your alternator charging system. The headlights will become dim due to reduced battery voltage.

A faulty alternator could ruin a perfectly healthy battery, which would put you further back from a solution than where you started. Don`t fret as diagnosing your vehicle`s electrical problem is so easy that anyone can do it by running these tests.
Can you top your coolant up with water? Coolant should only be topped up with water in case of an emergency when the coolant liquid level is lower than it should be. While topping up with water will help you get safely to the nearest RAC Approved Garage and identify any issues, it shouldn`t be relied upon.
Can a Bad Car Battery Cause Computer Problems? A faulty battery can have an impact on all of your automobile`s electronic components, including the car computer. If a malfunctioning battery is unable to provide the necessary electrical energy to a computer, it could result in issues.
Can a Bad Battery Cause Electrical Problems? Yes, if your battery is underperforming it can cause systems within the vehicle to malfunction. A bad battery can also result in air conditioners, stereos and other applications not receiving enough power to function properly.
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.

the most relevant questions and answers related to your specific issue

Car won’t start. The check engine light, battery light, and oil change light are coming on. I tried jumping the car and nothing happened. Why won’t my car start?
ANSWER : Hi and thanks for contacting Your Mechanic. If sometimes your vehicle will start with the new alternator and sometimes it won’t, then there is a loose connection in your charging system. Check all of the wires to the alternator and to the battery. Make sure that the battery cables are clean and tight. Make sure that the wires to the starter are clean and tight. A loose ground to the ignition system will cause the vehicle to not crank over. Check all of the ground wires from the battery to the starter. Make sure that they are clean and tight. If you need further assistance troubleshooting your no start situation, then seek out a technician, such as one from Your Mechanic, that can assist you.

2005 Chrysler 300C changed battery and alternator. Car started, ran, and then battery light came on. Shut car off and wouldn’t start.
ANSWER : Hi. There is a couple of things that could be wrong here. The battery or alternator that was just installed could be defective. Theses parts need to be tested for proper operation. There also could be a fuse, fusible link, or wiring for the battery or charging system that is blown or broken causing the battery light to come on.

The codes that you have will cause the car to shut down, run rough, or not start at all. The crankshaft sensor and camshaft sensor should be replaced. I suggest having a certified technician from YourMechanic come diagnose the charging system and check engine codes to help you proceed with correct repairs.

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.

Water was spilled in the trunk which soaked the car battery. Car won’t start now. Does water destroy a car battery?
ANSWER : Hi, thanks for writing in about the concern with the BMW 320i. If the battery was submerged in water then it’s completely possible for the battery to short out and die. Your friend will need to have the battery replaced. Also be sure to get all of the water out of the trunk. Have a certified technician, like one from YourMechanic, help you guys out if you need assistance with replacing the battery. Good luck.

Battery and oil light come on when trying to start car, take keys out try again car starts no problem and lights go away
ANSWER : Of course, don’t switch gears without being fully stopped, unless your Owner’s Manual or the manufacturer has alternative advice. However, the gear shift issue has no relation to the no-start problem you are describing. Inasmuch as you only have 6,000 miles on the car, the "constant on and off" that you believe has occurred is meaningless in comparison to the expected total vehicle service life. That is, assume what you perceive as "constant on and off", during merely 6,000 miles, might be equivalent to using the car "normally" for three years. A new car should be trouble free for at least 5 years, unless there is a defect, so your "constant on and off" is not a causal factor for any fault on the vehicle. What you might have is a defect in the ignition switch, or perhaps the immobilizer system, but if the problem is not in the switch itself, clearly there is an electrical problem.

If your vehicle is under warranty, by law the dealer MUST repair the issue you are describing within a prescribed time frame and number of "attempts", otherwise the dealer will run afoul of Federal and state Lemon Laws that give you very specific rights, and recourse (contact an Attorney; we are Mechanics, NOT attorneys). Consequently, if the vehicle is still under warranty, to save yourself money do be sure to seek a resolution from the dealer. If the vehicle is not under warranty, obviously a certified Mechanic from YourMechanic could identify the electrical fault and resolve this for you. If you want to go that route, please simply request a no start diagnostic -electrical system and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

in my car battery warning light appearing while driving.so I have replaced both battery and alternater still light is on
ANSWER : As you may yourself have seen, there are many reports of this fault with the Civic, that is a battery or alternator is replaced only to have the warning light fail to extinguish despite checking every conceivable electrical possibility. Your only recourse is to have a certified mechanic go through that exercise with your car and that involves first attempting to "re-set" the light. If the warning light returns, the alternator output has to be carefully measured both loaded and unloaded. All terminal connections have to be verified including all grounds. Fuses have to be checked for integrity (continuity) and the possibility of shorts, in for example dash wiring, has to be checked. To request this repair, simply request an electrical components diagnostic and the responding certified mechanic will seek a resolution to this.

My battery light keeps coming on and radio went off and on then off completely then car lost power toyota avalon 2000
ANSWER : Hello. If the engine will not stay running then the alternator is bad. The battery will also need to be load tested as a bad alternator can also cause the battery to fail.

When I come across this problem I always check the alternator and battery, as well as all of the connection first. Most of the time just the alternator needs to be replaced.

If you want to have your battery light diagnosed, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose and repair this issue.

Car started to slow down and then the check engine light, battery, and engine oil light came on. What could cause this?
ANSWER : Hi there. It is possible that the battery cable came loose or the wires to the oil pressure sensor has came loose or failed. Check the battery cables and make sure that the terminals are tight and clean. Check the wires to the oil pressure sensor and make sure that they are connected and not broken. If everything looks good, then the oil pressure sensor may have failed. Plus, check the computer for codes and see what is stored. This will lead you to the part that could have failed. I recommend replacing the oil pressure sensor then checking to see if the lights will go out. If you need further assistance troubleshooting your vehicle, then seek out a technician, such as one from Your Mechanic, that can assist you with the warning lights that came on.
