As leading car radiator specialists here at MRS Heat Transfer, we have an extensive amount of knowledge and expertise and we can fix and repair all manner of vehicle radiators. But what are the signs that show that your car radiator has a problem?

What are the most common radiator problems and what are the symptoms of these?

Car radiators are made up of a number of crucial components which means that these can experience a number of different and varied problems, each presenting a range of signs and symptoms. The most common radiator problems include:

  • Leaky hoses
  • Faulty thermostats
  • Cracks or holes in the radiator¬†
  • Broken water pumps
  • Broken radiator fans

What are the symptoms of a leaky car radiator hose?

A leaky car radiator hose has several obvious signs and symptoms to look out for, including:

  • A steadily rising engine temperature resulting in an overheating warning light on the dash
  • A small amount of steam rising from the bonnet with larger amounts of steam indicating a potentially larger leak
  • Coolant leaks on the ground when the car has been parked
  • Fluid or residue on different areas of the engine

What are the symptoms of a faulty car radiator thermostat?

If your car radiator thermostat is broken there are a number of symptoms to look out for including:

  • A very high engine temperature reading, which happens quite suddenly when driving and causes the overheating warning light on the dash to come on
  • Dramatic changes to the engine temperature- this is caused when the thermostat tries to recalculate the flow and temperature of the coolant
  • Coolant leaks around the area of the thermostat
  • Steam coming out from under the bonnet

What are the symptoms of cracks or holes in the car radiator?

Cracks or holes in the radiator itself can cause a range of problems including the usual factors like a resign engine temperature, steam from under the bonnet and visible coolant leaks on the floor or engine. However, what specifically can indicate a crack or hole in the radiator is if steam is blowing directly from one area of the radiator itself.

What are the symptoms of broken car radiator water pumps?

If your car radiator water pump is broken or faulty the symptoms to look out for include:

  • An overheating engine with the overheating warning light on the dash
  • A high-pitched whining noise coming from the front of the car- this is caused by a loose pulley
  • Steam coming from the radiator
  • Coolant leaking directly from the water pump, right at the front of the car.

What are the symptoms of broken car radiator fans?

A broken car radiator fan can present a range of symptoms including:

  • A steady and gradual rise in engine temperature when driving at low speeds and an overheating warning light on the dash
  • A small amount of steam rising from under the bonnet

What is more unusual about the symptoms of a broken car radiator fan is that the problems associated with this will not be noticeable when driving at higher speeds or on faster roads.
