An engine cooling fan runs continuously when an electrical or mechanical fault signals the cooling system to stay in maximum heat-rejection mode, or when the engine is actively overheating. Common triggers include a stuck-closed fan relay, a failing engine coolant temperature sensor, low coolant levels, high air conditioning refrigerant pressure, or a locked mechanical fan clutch.

Car warning signs that demand immediate service include a flashing check engine light, a spongy or sinking brake pedal, deep engine knocking, rapid cooling system overheating, persistent oil or brake fluid leaks, and heavy steering wheel vibration. Continuing to drive when these warning signals appear risks total system failure, catastrophic mechanical breakdown, and severe safety hazards on the road.

What I See Most Often with Radiator Problems in Clinton

## Identifying the Root Causes of Car Radiator Failure

I have spent plenty of time under hoods at our service center, and I can tell you that most engine overheating issues usually trace back to a few specific failures within the cooling system. The most frequent culprit is a low coolant level, often caused by a slow leak that a driver might not notice until the temperature gauge starts climbing. I also see many cases where a thermostat gets stuck in the closed position,
