When you notice the temperature alerting light is gleaming bright red on the dash, the needle at the temperature gauge is heading to the high mark, or steam is coming excessively from under the hood, it is time to leave the road and turn off the engines before they fry from overheating.

In general, any signs of overheating is always a serious problem with your car, so the best thing that you should do is to shut down the car to avoid further damage. If you try to drive a vehicle with an engine that is overheated, it can make the cylinder heads warped as well as damage the internal parts of your engine such as pistons, camshafts or valves.

Even when you allow the engine to cool down for 1 hour and top off the radiator by a mixture of 50% anti-freeze and 50% water might not fix what is wrong. The following are a couple reasons why an engine would overheat:

  • The level of coolant would be very low due to long-term lack of care or a leak in the radiator hosepipe or the radiator itself. In general, coolant moves around inside the engine area to make sure it is cool, and the hole would be in this area, or from the heater hosepipes or the water pump. Coolant that is used for a long time will lose its corrosion-inhibiting elements, which eventually allows rust to build up and lead to damage.
  • The thermostat which allows the coolant to move around might be blocked in the closed area or a clog might have emerged, probably from debris or dust in the cooling system.
  • The cooling fins of the radiator are blocked with debris or the cooling fan of the engine has stopped working so that the flow of air which reduces the temperature of coolant would be restricted.
  • The cap of the radiator has become bad and would not maintain enough amount of pressure in the cooling system, which allows the coolant to boil over (engine generally works at from 210 to 220 Fahrenheit degrees).
  • The head gasket which seals the area between the engine block and cylinder head might have broken, which allows the coolant to leak into the combustion chamber. In this situation, you would notice the steam comes out of the exhaust system.
  • The water pumps have stopped working or the belts which drive it is slipping or cracked so that the necessary amount of coolant is not pumped.
  • You have been towing a trailer in 5000 pounds with a car that is designed to tow just 2000 pounds, which exceeds the cooling capacity of your vehicle. (You possibly strained the transmission as well).

To sum up, checking the level of coolant in the overflow tank of your engine on a frequent basis would definitely help to prevent potential problems. If you need to continue topping the coolant off, that is a sign of a small leak which need to be paid special attention before it becomes a serious issue.

To read more useful tips as well as hands-on experience on changing and checking the coolant in your car, our site is definitely a perfect choice for you. In general, getting the coolant in the engine checked and the whole system of your car examined frequently by a professional mechanic is probably a good way to keep the cooling system as well as the radiator from any potential disasters while you are driving on the road.
