ENGINE COOLING SYSTEM

ENGINE COOLING SYSTEM

Inside the car engine, fuel is burning creating a very high temperature – part of the heat goes out from the exhaust system and part of it soaks into the engine heating it up. The best temperature for a good function of the engine is 93 degrees, temperature which allows the combustion chamber to vaporize the fuel reducing emissions and providing better combustion, oil that lubricates the engine has a lower viscosity so the engine wastes less power and the metal parts wear less.
THE MAIN COMPONENTS OF THE ENGINE COOLING SYSTEM ARE:
  • Thermostat
  • Upper hose
  • Radiator
  • Fan
  • Water pump
  • Transmission cooler
  • Lower hose
  • Reserve tank
  • Heater core
  • Heater hoses
  • Pressure cap
THERE ARE 2 TYPES OF ENGINE COOLING SYSTEM 
  • Air Cooling System– very few modern cars are using nowadays the air cooling system which is represented by a fan that blows air on the engine aluminum fins (engines with aluminum fins are found only together with the air cooling system) taking the heat away from the cylinder and transferring it to the air.
  • Liquid Cooling System – means that circulates a fluid through pipes and passing it in the engine, cooling it while absorbs the heat. Once the heated fluid leaves the engine, it passes through a radiator or heat exchanger transferring the heat from the fluid to the air.
SYMPTOMS OF A DAMAGED COOLING SYSTEM
  • Car engine is overheating
  • Coolant is disappearing
  • The car is shutting off while driving
  • Steam is coming from the radiator
  • Your AC won’t turn on or off
Expert advice: - Check antifreeze coolant level periodically. Only use a 50/50 coolant and distillated or deionized water.
  • Bring your car regularly for an inspection to check if hoses or tighten hose clamps are curved or change their initial shape.
  • Inspect belts periodically. Worn or glazed belts should be replaced. (ask our expert to show you how you can do the periodically check-up by your own)
  • If there any problems with a spare part of the cooling system, that part should be replaced with an original spare part and the recommendations and specifications of the manufacture should be followed in detail.
  • Always check the level of coolant (caution: never open the radiator pressure cap if the engine is hot!)
