The Most Common Causes of Radiator Leaks

  • Corrosion: Over time, the metal components of your radiator can corrode, leading to leaks. This is often caused by exposure to water, air, or other environmental factors.
  • Loose Connections: If the connections between your radiator and the pipes are loose, it can cause leaks. This is often due to improper installation or wear and tear.
  • Blockages: If your radiator is clogged with debris or sediment, it can cause leaks. This is often due to a lack of maintenance or poor water quality.
  • Manufacturing Defects: In some cases, radiator leaks can be caused by manufacturing defects. This is often due to poor quality control or design flaws.

Symptoms of a Radiator Leak

  • Water Leaks: The most obvious symptom of a radiator leak is water leaking from the radiator itself. This can be a slow drip or a full-blown gush, depending on the severity of the leak.
  • Noisy Radiator: If your radiator is making unusual noises, such as clunking or banging sounds, it could be a sign of a leak.
  • Reduced Heat Output: If your radiator is not producing heat as efficiently as it should, it could be a sign of a leak.
  • Increased Energy Bills: If your energy bills are increasing without any changes to your usage, it could be a sign of a leak.

Identifying the Source of the Leak

Before you can fix the leak, you need to identify the source. This can be a challenging task, especially if you’re not familiar with radiator systems. Here are some tips to help you identify the source of the leak:
