A radiator is indispensable to the vehicle’s health. They perform the important task of cooling the radiator fluid, which keeps the engine running at the right temperature. If your radiator has a coolant leak, the car engine can overheat and break down. Here are some signs that your radiator might be leaking and needs repair:
Puddle under the car
If you notice a small puddle under your car when parked, it could be a coolant leak. In most cases, what you see is just wanted that has condensed from the air. However, you should take a closer look and check if the fluid is bright green or pink. If yes, then it is definitely a sign of coolant leak.
Low coolant level
With regular use, coolant levels may drop gradually, but a consistent and sudden drop may indicate a leak.
Bubbles or steam coming from the radiator
A radiator leak is a common reason behind an overheating engine. If your temperature gauge is entering the red zone and you also see bubbles or steam coming from the radiator, it is a sure sign of a leak.
Corrosion
Corrosion or discoloration are also common signs of a radiator leak. Corrosion occurs when the radiator’s metal reacts with moisture and oxygen and leads to the formation of rust. This weakens the radiator’s structure and creates cracks and holes through which coolant can leak.
Engine overheating
While operating, your car’s engine vents the heat through the radiator. When the coolant leaks from the radiator, it can cause frequent overheating. This can lead to serious engine problems.
Broken hoses
The radiator hoses circulate coolant from the radiator to the engine. Over time, the hoses can become brittle, crack, and begin to leak coolant. If the hoses are visibly worn and have cracks, they should be replaced immediately even if you have not noticed other signs of a leak.
What causes leaks in the radiator?
The most common cause of radiator leaks is corrosion. The radiator, hoses, and connections collect rust and sediment, which can punch holes in the radiator over time. Sometimes, pool service practices such as overfilling the radiator can cause leaks due to increased pressure. A malfunctioning thermostat or heater can create excessive heat and put pressure on the radiator.
A loose or damaged radiator cap can reduce pressure in the radiator and tank, which makes it harder for the coolant to protect the engine. Another culprit could be a worn head gasket. It can allow the coolant and engine oil to mix, making it difficult for the engine to keep running.
External impact or trauma can cause physical damage to the radiator and can result in punctures or cracks. Road debris, collisions, or improper service practices can cause structural damage to the radiator’s core or tanks. Even a minor external trauma can impact the radiator’s structural integrity and lead to leaks.
What should you do if you suspect a radiator leak?
A car radiator leak should not be ignored at any cost. If you notice any signs of a leak, you should immediately take your vehicle for repairs. You must maintain a proper coolant level in the radiator to ensure proper functioning and prevent damage to the engine. By staying proactive with radiator maintenance, you can protect your engine’s health and performance.
