5 Symptoms of a Failing Radiator

July 19, 2023

It can be quite alarming to see steam billowing from under your car's hood. Your first instinct should be to pull over. Surprise, surprise - you find that your engine is overheating. The culprit behind most engine overheating incidents is faulty radiators. The vehicle's radiator plays a vital role in keeping the engine cool, and any signs of a malfunction should not be taken lightly.


Understanding the Role of the Radiator

The radiator is a crucial component of your car's cooling system. It works by dissipating the excess heat generated by the engine, preventing it from overheating. Coolant flows through the radiator, releasing heat to the surrounding air and keeping the engine at optimal temperature.


Signs of a Failing Radiator

  1. Overheating Engine: One of the most apparent signs of a failing radiator is an overheating engine. If you notice that your temperature gauge is consistently in the red zone or if steam starts coming out from under the hood, it's a clear indication that your radiator may be struggling.
  2. Leaking Coolant: Coolant leaks are another common sign of radiator issues. If you notice puddles of green, yellow, or pink fluid underneath your vehicle, it's likely that your radiator is leaking. 
  3. Low Coolant Levels: If you frequently need to top up the coolant or notice a sudden drop in coolant levels, it could indicate a radiator problem.
  4. Rust or Corrosion: Radiators are susceptible to rust and corrosion over time, which is why you should assess your radiator for signs of rust, especially around the seams and fittings. Rust can weaken the radiator's structure and lead to leaks in the foreseeable future.
  5. Sludge Buildup: Over time, contaminants can accumulate in the radiator, forming sludge. This sludge can restrict coolant flow and hinder the radiator's ability to dissipate heat effectively.


Addressing Radiator Issues

Regular cooling system maintenance is key to preventing issues surrounding a faulty radiator. We urge you to please do not ignore the signs of a failing radiator. Instead, please turn to F & M Automotive Body & Repair today to schedule an inspection and necessary radiator repairs.
