3 Common Signs of a Leaking Radiator

Your radiator is an important component of your cooling system, playing a critical role in managing the engine temperature and preventing your engine from overheating. Therefore, it’s vital to ensure your radiator is in good working condition.

But what happens if you think there’s a radiator leak? First, know a radiator leak is a common occurrence in many vehicles. Leaks usually occur when the tubes carrying coolant in the radiator become damaged. It’s important to know if you have a radiator leak since it can leave you stranded if your vehicle overheats. Consider these three common signs of a leaking radiator from 1-800-Radiator & A/C franchises:

Visible Leaking Fluid

Perhaps the most common sign of a radiator leak is a puddle underneath your vehicle. Take a look under your engine while your vehicle is parked to see if there’s any fluid on the ground. If you see fluid that is bright green, orange, or pink in color, it’s a sure indicator of a leaking radiator.

Drop in Coolant Level

While it’s normal for coolant levels to gradually drop over time as you drive your vehicle, a drastic drop in your vehicle’s coolant level is generally a good indication that your radiator is leaking. If you believe there may be a leak, fill your coolant reservoir and check the level after several days of normal driving.

Discoloration or Corrosion

A leaking radiator can be due to discoloration or corrosion. When coolant is discharged it causes discoloration on the radiator, which results in leakage. The best way to examine any leakage due to discoloration or corrosion is by first cleaning the hoses and radiator with water. Then start the engine and carefully look for any leakage. If you spot the leak in one of the hoses, it can be fixed fairly easy. However, if it’s in the radiator, a mechanic will be required to make the fix.
