What Causes The Battery Light On And Engine Overheating?
Let’s understand what might cause your battery light to turn on and your engine to overheat.
Why Is Your Battery Light On?
There can be a lot of problems causing the battery light to turn on. Some of them are listed below:
1. Battery is Damaged
Your car’s battery is supposed to be working for a 4 to 5-year lifespan, as told by the manufacturers. But if you take care of your car’s battery it can go up to 6 years. With age, the plates can break and the electrolyte solution can leak. If you keep using your car’s battery even after its lifespan then it can cause your battery light to turn on. If this happens then the battery needs to be replaced with a new one.
2. Alternator Gone Bad
The alternator supplies direct current (DC) power. Your alternator is also responsible for charging your car battery while driving. The alternator works by converting mechanical energy into electrical energy. When your engine is turned on, your alternator powers a drive belt that rests on a pulley attached to the alternator. The ideal voltage of an alternator should lie between 13.6 volts and 14.6 volts. If its voltage is less than 12 volts, the battery light is turned on and you’ll have to replace your alternator. The voltage regulator, the component that limits the output to a safe limit of 14.5 volts, can also be the culprit if it isn’t working as it should.
3. Damaged Alternator Belt
The alternator belt’s job, or drive belt, is to transfer power from the engine crankshaft to various other components; these include the alternator (of course), the air conditioning, and the power steering. Older cars had a selection of belts to take care of these tasks, but modern cars need only one. After an age, the alternator belt reaches a certain age and can be broken anytime. If your alternator belt is broken then your battery light could be turned on.
4. Your Battery Terminals Are Corroded
Battery terminals are important since they provide connections and if the terminals are covered with corrosion then they will act as bad conductors for electricity and your connection will be poor.
5. Battery Cables Are Loose
The Cables that provide connectivity inside your battery if left loose then they might be unable to provide good connections and the loose cables may lead to poor battery connections. The battery cables should fit snugly around the battery terminals to provide a good connection. You should not be able to rotate the cable end by hand around the battery post. If it is that loose then your might have to tighten it.
6. Wiring Are At Fault
If your wires are loose or disconnected at any point this might lead to broken connections and the power won’t be able to travel from one point to another then your battery light will turn on to tell you that there is some problem there in the battery.
What Are The Common Causes Of Overheating Of Engine?
There are a lot of issues overheating the engine, Some of the common ones are listed below:
1. Your Cooling System Are Leaking
Any of the machinery which provides cooling in your car can cause overheating of your car. Leaks in hoses, water pump, heater core, thermostat housing, the radiator, head gasket, freeze plugs, and a few other things can all lead to problems with the vehicle’s cooling system.
2. Damaged Thermostat
The thermostat ensures the coolant may pass properly through the radiator whenever necessary. It is a kind of a valve that allows the coolant when required and stops it when not required. If due to some reason the valve gets stuck in the closed position then there might be issues, since if there is a requirement of a coolant but the valve is closed and due to this there is no coolant passing through it. And the engine can get overheated.
3. Failing Radiator
Any leak or clogging in your radiator can lead to a failing radiator, and if your radiator is failing then it will eventually cause your engine to overheat since no pulling away of heat is being done now.
4. Worn Out Or Cracked Hoses
if your hoses are cracked or possessing some holes which will make your engine leaky and will disrupt the coolant’s flow. Your water pump can’t circulate coolant that’s not there due to it having leaked out from one of the leaking hoses.
5. Bad Water Pump
The water pump is a simple centrifugal pump driven by a belt connected to the crankshaft of the engine. The pump circulates fluid whenever the engine is running. The water pump uses centrifugal force to send fluid to the outside while it spins, causing fluid to be drawn from the center continuously. The water pump is the heart of your cooling system and if it’s not working properly, your vehicle lacks enough pressure to propel engine coolant throughout your cooling system. Any problems with the pump from erosion, leaks, etc can cause your vehicle to overheat.
There are several reasons that can cause your battery light to turn on or your engine to overheat now you know all the common reasons that are responsible for your car to show these symptoms. The most ethical thing you can do is to take your car to an automotive expert whenever your notice any of the two problems, that expert can easily fix your problem and the amount he will cost will totally depend on which part is damaged and what is the labor cost around your area.
