If you are in a vehicle that is overheating, do not try to drive farther. Pull over, stop driving and turn the vehicle off. Actions can be taken to assess any issues, though the best course of action is to have the vehicle towed to your nearest Goodyear Auto Service.
What does a cooling system do?
Before getting into reasons why an engine can begin to overheat, it’s good to understand what an engine’s cooling system does. The overall cooling system keeps a standard operating temperature for the engine by circulating coolant, or antifreeze, through the engine to the radiator, thus pulling heat away from the engine.
What happens when an engine overheats?
Today’s engines are typically built to be durable, but when heat generated by a vehicle’s motor is well above the normal operating temperature, the devices made to cool this heat distribution may begin to fail, potentially causing permanent damage to not only the engine, but also the gaskets, hoses and seals that are designed to keep the engine running..
Common reasons for overheating engines
There are a variety of reasons why a vehicle’s engine can overheat. Certain examples may be quicker fixes, such as refilling your antifreeze, but other issues may be more permanent if not properly taken care of by a professional.

There are a few different reasons that your coolant might not be building pressure. You might have a busted radiator cap, or you might have a leak or busted water pump. Either way, low coolant pressure is going to lead to an overheating engine.
Why won't coolant flow through my car?
Your vehicle’s coolant flows through the radiator’s fins to cool down, and if those fins are clogged or blocked, you won’t get enough coolant flow through your engine to effectively cool it down. Another problem is if debris blocks the front of your radiator.
What to check for when an engine is overheating?

Why does my car overheat?
1. Your engine coolant is low. The most likely culprit of your car overheating has to do with your liquid coolant. Most modern cars have a liquid-cooling system—whereas older cars are air cooled. Coolant, also called antifreeze, takes on heat to prevent your car from overheating.
How to stop a car from overheating?
What You Should Do Next: 1 Pull over to a safe area if possible. 2 Turn off your air conditioner and roll down your windows. 3 If the overheating continues, turn on your heat and blower to transfer the heat to the passenger compartment. 4 Open the hood of your car to let things cool. 5 If you are stuck in traffic and the temperature continues to rise, put your car in neutral or park and rev the engine — this helps draw more liquid and air through the radiator. Additionally, try not to brake hard or fast, as this will heat the engine up even further.
Why does my car keep stalling?
If your thermostat is malfunctioning and displays a false reading (i.e. tells you that your car’s temperature is normal when it’s too hot), the coolant is not released and the car becomes progressively hotter. If this occurs continually, it can cause stalling and billows of smoke.

Why does my engine overheat?
Some of the most common causes of engine overheating are: Coolant leaks resulting in low coolant levels. Defective thermostat.
Why do head gaskets need to be sealed?
Head gaskets provide a seal between the cylinder head s and block to prevent compression loss. They also seal oil and coolant passages to keep oil and coolant from mixing. As mentioned above, really high temperatures can cause the cylinder heads to swell. This enables the cylinder head to crush the head gasket. Damaged head gaskets, in turn, may cause compression loss between cylinders and may even cause coolant to leak into the cylinders, damaging other parts of the engine. Repairing a damaged head gasket is especially tedious, because you’ll need to remove the cylinder head to access it.
Why do cylinder heads warp?
Cylinder heads expand and warp when the engine is overheated for an extended period of time, which could often result in a loss of compression and/or internal coolant leaks. Head Gasket. Head gaskets provide a seal between the cylinder heads and block to prevent compression loss.
What causes a leak in the exhaust valve?
Engine overheating can also cause major damage to the exhaust valves. These valves may stick or scuff in their guides, leading to significant compression leaks.
What happens when fuel combusts prematurely?
