Signs That There May Be A Problem With Your Radiator

Your car radiator has dual roles. It not only heats the interior of your vehicle, but it also cools down your engine and prevents it from overheating. Taking care of your radiator is essential to maintain the life of your car. So how do you know if there’s a problem? Let’s take a look at some signs that there may be a problem with your car radiator.

Leaking Coolant

The coolant that flows to your engine runs through your radiator. When there’s a leak, the coolant will begin to pool on the ground underneath your car. If you notice puddles underneath your vehicle where it’s regularly parked, take it to your mechanic right away. They will do a pressure test by adding a colored dye to your coolant system. If the colored liquid leaks out, it may be time to replace your radiator.


There are several different factors that can lead to an overheating vehicle, but if your car is frequently overheating and you’ve ruled out other possible causes, it may be your radiator. The radiator is the main component in cooling down your engine, so if it’s not functioning correctly, it will not be able to maintain a steady temperature. It’s crucial that you take your car to your mechanic as soon as possible to avoid more extensive damage than just a radiator replacement.

Low Coolant

If your coolant light is frequently lit up on your dashboard, it may be a sign your radiator needs servicing. Don’t just keep refilling it; ignoring a leak can lead to more serious problems.


The coolant in your car should always be yellow, green, red, or blue. As your radiator breaks down, rust and other particles can cause it to look brown or black. If you notice this sludgy substance under the hood, have it checked right away.

All these signs are indications that your radiator should be looked at by a professional as soon as possible.
