How To Tell The Signs Of A Blocked Subaru Engine Radiator

The engine radiator in your Subaru plays a critical role in keeping the engine cool by dissipating heat generated during operation. A blocked radiator can hinder the cooling process, leading to overheating and potential engine damage. Understanding how to spot the signs of a blocked radiator early can save you time, money, and hassle. Empire Subaru is here to help you identify these symptoms and take the right steps to maintain your Subaru in top shape.

1. Symptoms of a Blocked Engine Radiator

A blocked radiator doesn’t always make itself known immediately, but there are several key signs that could indicate a problem:

• Overheating Engine: The most common symptom of a blocked radiator is engine overheating. If your Subaru’s temperature gauge rises above the normal range or the warning light illuminates on your dashboard, this is a clear indication that the cooling system is not functioning properly, potentially due to a blocked radiator.
• Coolant Leaks: Blockages in the radiator can lead to pressure build-up in the system, which can cause coolant leaks. If you notice a puddle of coolant beneath your vehicle, it's worth having the radiator checked for blockages and damage.
• Reduced Heater Performance: Another sign of a blocked radiator is poor heater performance inside your car. If the heater is not blowing hot air as it normally should, the coolant may not be circulating correctly, often due to a blockage in the radiator.
• Strange Noises: You may hear unusual gurgling or hissing noises coming from the engine compartment. This can be a sign that air is trapped in the cooling system, possibly due to a blockage in the radiator.

2. What Causes a Blocked Radiator?

Several factors can cause a radiator to become blocked or restricted:

• Debris Build-Up: Dirt, leaves, and other debris can accumulate in the radiator over time, blocking the flow of coolant. Regularly checking and cleaning the front of the radiator can help prevent this issue.
• Corrosion: Over time, the components inside the radiator can corrode, leading to a build-up of rust or sediment that can block the flow of coolant. Corrosion can also weaken the radiator, making it more susceptible to leaks and damage.
• Coolant Contamination: Using the wrong type of coolant or neglecting to replace coolant regularly can cause contaminants to build up and clog the radiator. Ensuring you use the correct coolant for your Subaru can help avoid this issue.

3. What to Do if You Suspect a Blocked Radiator

If you experience any of the symptoms of a blocked radiator, it’s important to act quickly. Overheating or coolant leaks can lead to severe engine damage if left unchecked. Here's what you can do:

• Turn Off the Engine: If your Subaru’s engine starts overheating, turn it off immediately to avoid causing further damage to the engine.
• Check the Coolant Level: Ensure that the coolant levels are adequate. If levels are low, topping them up may temporarily help prevent further overheating. However, if the problem persists, you likely have a blockage in the radiator.
• Visit a Professional: A blocked radiator should be inspected and cleaned or replaced by a professional mechanic. Empire Subaru has the expertise and equipment to diagnose radiator issues and keep your vehicle running smoothly.

A blocked radiator is a serious issue that should not be ignored, as it can lead to significant engine damage if not addressed promptly. Recognizing the signs of a blocked radiator early, such as overheating, coolant leaks, and poor heater performance, will help you take the necessary steps to protect your Subaru.
