Diagnose Your Overheating Engine

By | March 7, 2014

When the weather is warm and you are in your car, you will depend on your car’s cooling system such as air conditioner. Like the car is also depends on its cooling system which has coolant that absorbs and circulates the heat through the system and send it out. Here we will see how to diagnose the overheating problems of engine.

  • The oil removes 75% to 80% of the excess heat of the vehicle’s engine. If there is any scarcity of oil in the engine that much of heat is not carried away. You can identify the oil level just by checking. In most cases, this is the only problem faced by many drivers.
  • There might be a problem in the plugged radiator. Because the cooling system’s liquid circulation can cut down and effect on the cooling efficiency of the system. For this your radiator has to inspect by a radiator specialist. Sometimes steam cleaning is enough for the radiator to do the job. If it is not the solution might be expensive.
  • A bad radiator cap can cause the engine overheat as it will keep pressure from building. Check your vehicle’s radiator cap with a tester.
  • Check for the leaks by pressurizing the cooling system.
  • Soft radiator hose can collapse and stop the coolant flow to the engine.
  • Check the water pumps. Even a brand new pump installed can also fail shortly. At higher RPMs the coolant flow is reduced as the impeller is spinning on the shaft.
  • Check the vehicle’s electric fan equipped.
  • Check the engine’s drive belts, they may be slipping or broken. If slipping, tight them and in case they are broken replace them.
  • If you find leaks in the cooling system repair and refill with coolant. If the cylinder head gaskets are not good, replace them.
  • Check for the ignition. The timing might be set wrongly. In that case, adjust the time.
  • Inspect the compression to determine any mechanical problems and the engine condition.
  • If the thermostat of the engine got stuck, replace it.

First, we can recognize the sign of overheating either with a temperature gauge needle shows the red zone or temperature or check engine indicator light on your vehicle dashboard. The best practice for overheating is preventive. For well flowing and to keep the system clean, you should flush the radiator timely.
