Your car's radiator is like its lifeblood, keeping your engine running smoothly and preventing overheating. But when it fails, you're left feeling stuck and frustrated. As a digital expert, I'm here to help you identify the signs that indicate your radiator is on its last leg and needs a replacement.

Leaks and Drips: A Clear Warning Sign If you've noticed a green or yellow liquid leaking from under your car, it's likely coolant, which is a sign that your radiator is failing. Coolant is a critical component that regulates your engine's temperature, and a leak can cause it to overheat, leading to costly repairs. Don't ignore the puddles under your car – it's a clear warning sign that your radiator needs attention.

Other Signs of Radiator Failure In addition to leaks, there are several other signs that indicate your radiator needs replacement:

• Overheating engine: If your temperature gauge is consistently in the red zone, it's a sign that your radiator is not doing its job.
• Coolant level is low: If the coolant level is consistently low, it may be a sign that there's a leak or the radiator is not holding liquid.
• Engine knocking or clunking: Strange noises from your engine can indicate that the radiator is failing to circulate coolant properly.

Actionable Insights: When to Replace Your Radiator If you've identified any of these signs, it's time to take action. Here are some practical tips to consider:

• Check your owner's manual: Consult your owner's manual for guidance on radiator maintenance and replacement.
• Get a professional inspection: A mechanic can diagnose the issue and recommend a replacement.
• Don't delay: Delaying a replacement can lead to costly repairs and even engine failure.
