5 Signs and Symptoms of Your Car Overheating
The internal combustion engine is comprised of several rotating parts and components. Some of these components rub against each other and create friction. Anytime you have metal parts creating friction, there is going to be a lot of heat generated in the process. The engine depends on coolant and oil to keep its components cooled down. Oil is more for lubrication, but it adds extra cooling to the components. The coolant is the main ingredient for cooling the engine. If you don’t have coolant or a functional cooling system, then you will have heat problems in the engine.
If something were to happen where the engine’s components could not be cooled, then car overheating takes place. This doesn’t mean that your entire car becomes overheated. It just means the engine itself is overheated, which is bad for the car. An overheated engine will cause many of its components to become damaged or worn out. Once that happens, the engine will not be able to produce the energy needed to accelerate the vehicle and provide power to other components which depend on it.
The Top 5 Symptoms of Car Overheating
There are several symptoms that you will easily notice when your car overheats. Below are the top 5 symptom of car overheating.
Temperature Gauge is Red – Every car has a temperature gauge which indicates the temperature of the engine. In normal circumstances, you will see the needle in the middle of the gauge. This means the engine temperature is where it should be. But if the needle falls into the red zone on the gauge, then it indicates the engine is overheating. You will see that needle go there when this happens to you.
Coolant Leakage – If you are driving your vehicle and you notice a trail of coolant left behind, then you have a coolant leakage problem going on. This is the cause of any engine overheating problems that you experience at that time. If there is not enough coolant to cool down the engine, the components of the engine will create too much heat. If they are not cooled down soon, the components will get worn out and damaged.
Weak Engine Performance – When an engine overheats, the pistons of the cylinder bore will expand. This limits the rotation ability of the crankshaft. Once that happens, the engine will not be able to generate enough power to accelerate the vehicle on demand. It will either take longer to accelerate or you simply won’t be able to accelerate past a certain speed.
Steam – Is there steam coming out of your hood? This is the most visible indicator of an overheated engine. The steam forms when the coolant in the coolant reservoir is boiling. Perhaps the coolant is not circulating through the engine properly and is stuck in the reservoir. As the heat from the engine increases, the coolant starts to boil and emit steam. You won’t be able to drive too much longer at this rate. So, a steaming hood should motivate you to take your vehicle to the mechanic and get the problem solved.
Engine Noise – A ticking noise coming from the engine could be a sign that you need to lubricate and cool down the moving components in there. For instance, if the coolant is not flowing properly and doing its job, the oil can still become overheated from the engine. This will thin out the oil and reduce its ability to lubricate the components. The first sign of this will be a ticking noise as the moving components move against each other.
Tips to Fix Overheating Issue
When you have an engine overheating problem, there is still time to remedy the situation before it causes permanent damage to your engine. You should first examine which symptoms you are experiencing. For instance, if you have a coolant leakage problem, then you’ll want to repair the leak and replace the lost coolant in the engine. Just pay attention to the symptom and you will trace it back to the cause of the overheating issue. Basically, make sure the coolant and oil are circulating properly and that there are no leaks. If you can do that, it will solve the overheating issue.
