Automotive Engine Overheating – Common Causes And Consequences


Radiators allow the scorching heat generated by your engine to be dissipated into the air. Consequently, Keeping the engine running at its optimal temperature. A problem with your radiator can be a big issue, for the overall functioning of your engine. So, The operating principles for an automotive radiator are fairly straightforward.

Let’s Start With The Radiators¬† Location And Basic Function

The radiator is at the front of your vehicle, behind the grille. The radiator itself consists of a number of tubes through which coolant flows. The tubes are in between two tanks that hold coolant at the inlet and outlet. Attached to these tubes in the radiator core are fins, which radiate heat into the air. Consequently, having different coolant flow patterns all with their own particular advantages and disadvantages.

Following The coolant Path:

  1. So, The cooling process begins when the water pump sends coolant to the engine.
  2. The coolant flows around the cylinders and picks up heat; produced by combustion and friction in the engine.
  3. The heated coolant then enters the radiator, through the upper radiator hose.
  4. Furthermore, Flowing through the radiator tubes, which take on the heat.
  5. The heat is then conducted from the tubes into the fins; which dissipate the heat into the air.
  6. Air gets blown over the radiator; through the grill as the vehicle moves forward.
  7. Sometimes, Too much heat is generated; and the radiator just can not keep up.
  8. As a result, An electric fan is activated to speed up the process.
  9. Finally, the cooled coolant returns to the engine, to repeat its journey.

Radiators Can Suffer A Number Of Problems, But Some Are More Common Than Others.

Clogged Or Plugged Radiators

The most common problem is a clogged radiator. Corrosion inside the radiator can cause rust to enter the coolant; turning it into a yellow or brownish sludge. This sludge flows more slowly, and cannot cool the engine as effectively. Engine overheating may be a sign of a clogged radiator. Clogged radiators can also develop further corrosion which can eventually lead to leaks. This problem should be avoidable though, if you change the coolant at regular intervals.

Exterior Radiator Damage

Occasionally, radiators will develop problems from the outside rather than the inside. Rocks or other road debris can damage the radiator. This can lead to punctures and leaks or to bent or broken fins. Since the fins’ purpose is to increase the surface area of the radiator and radiate heat away; damage to the fins significantly dampens the radiator’s effectiveness. Rust and corrosion can also affect the outside of the radiator; leading to leaks or decreased effectiveness of the radiator fins.

Proper Grounding And Electrolysis

On rare occasions, more unusual problems can occur. If not properly grounded, the radiator may receive an electric charge. In aluminum radiators, this will cause electrolysis to occur. In this situation, an electrochemical reaction between the aluminum; and the coolant will cause rapid corrosion of the aluminum. Aluminum may also react poorly with old cooling additives. Copper tubes, because they are not as strong as aluminum, can blow out under pressure.

Damaged Transmission Cooler Leaking Internally

You could have another component in the radiator; for vehicles with an automatic transmission. Consequently, A separate tank mounted inside one of the tanks. Fittings connect this inner tank through steel tubes to the automatic transmission. As a result, Cooling the transmission fluid. It is possible for fluids to intermix, Because of internal damage.
