What You Should Know about Your Car’s Radiator?

A radiator is the most important part of your car as it prevents your car’s engine from getting hot enabling a smooth and uninterrupted drive.

Car radiators expert, Advanced Radiators, wants to ensure your car doesn’t breaks down in the middle of the road. Therefore, they’ve presented some tips you should consider:

  1. Apart from preventing the engine from getting hot, your car’s radiator also keeps lubricants and important fluids like power steering fluid and transmission fluid, cool.
  2. There are two types of car radiators:
  • Cross flow radiators: They use tanks present on the sides of the core to move the coolant around the core to disperse the heat.
  • Down flow radiators: These radiators have an expansion inlet tank on top of the core to help move around the coolant. These radiators are especially designed for bigger vehicles.
  1. Coolant is a solution created using antifreeze (ethylene glycol) and water.
  2. Antifreeze doesn’t allow the water in the radiator to freeze at cold temperatures.
  3. Antifreeze also keeps the water in the radiator from boiling up in hotter climates.
  4. The coolant level should be kept under observation; low levels of coolant can cause the vehicle to heat up. Fill the water to maintain the optimum level.
  5. The cooling system’s thermostat prevents abnormal coolant flow to the radiator.
  6. The cooling system and hoses should be examined watchfully as follows:
  • Traditional antifreeze that normally comes in blue colour (alternatives are also there) should be replaced twice every year.
  • Organic Acid Technology (OAT) antifreeze, which is normally red in colour (alternatives are also there), must be changed once in 5 years.800px-antifreeze_in_the_rad

  1. Rust and other damages on the radiator fins will affect the radiator’s performance, thus affecting the overall efficiency of the car’s engine cooling system.
  2. Don’t open the radiator’s cap when the engine is still hot. You might end up burning yourself.
  3. Dead insects, dirt or debris can clog up the radiator.
  4. Lift up the bonnet of your car to for radiator blockage. Blocked airflow can result in overheating the radiator.
  5. Internal clog in the radiator is difficult to discover. Try the following:
  • Use an infrared thermostat to the locate cold spots
  • As the engine cools down, open the radiator cap and see if the colour of the fluid got brownish or you find suspended debris.
  1. Radiators no longer have copper and brass cores as they have been substituted by aluminium cores and plastic tanks, because:
  • Aluminium cores are cheaper as compared to copper and brass cores
  • Aluminium cores are lighter in weight unlike copper and brass cores
  • Aluminium transfers heat better than other metals
  1. You should be careful if the radiator’s cap is faulty because:
  • Coolant can leak through a loose radiator cap

A slightly misplaced radiator cap can cause the pressure of the radiator water to change.
