Why is my Subaru overheating when I drive?
As a car owner, experiencing an overheating engine can be a stressful situation, especially when you're on the road. If you own a Subaru, understanding the common causes of overheating can help you address the issue promptly and avoid potential damage to your vehicle. In this article, we will explore the reasons why your Subaru might be overheating and what steps you can take to resolve the problem.
Common Causes of Overheating in Subarus
There are several reasons why your Subaru may be experiencing overheating issues. Here are some of the most common culprits:
- Low Coolant Levels: Insufficient coolant can lead to overheating. Check your coolant reservoir and refill it if necessary.
- Coolant Leaks: Leaks in the cooling system can cause a drop in coolant levels. Look for puddles under your car or signs of coolant on hoses and connections.
- Thermostat Failure: A malfunctioning thermostat can prevent coolant from flowing properly, leading to overheating.
- Radiator Issues: A clogged or damaged radiator can restrict airflow and coolant flow, causing the engine to overheat.
- Water Pump Failure: The water pump is responsible for circulating coolant throughout the engine. If it fails, the engine can overheat quickly.
- Faulty Fans: If the cooling fans are not functioning correctly, they may not provide adequate airflow to cool the engine.
Identifying the specific cause of overheating is crucial for effective repairs. Regular maintenance can help prevent these issues from arising.
Steps to Take When Your Subaru Overheats
If you find yourself in a situation where your Subaru is overheating, here are some steps you can take:
- Pull Over Safely: If you notice the temperature gauge rising, pull over to a safe location as soon as possible.
- Turn Off the Engine: Once parked, turn off the engine to prevent further damage.
- Check Coolant Levels: After the engine has cooled down, check the coolant levels and add coolant if necessary.
- Inspect for Leaks: Look for any visible leaks around the engine and under the vehicle.
- Call for Assistance: If you are unable to identify the problem, it’s best to call a professional mechanic for help.
Taking these steps can help mitigate damage and ensure your vehicle is safe to drive again. Remember, addressing overheating issues promptly is essential for the longevity of your Subaru.
Preventive Measures
To avoid overheating in the future, consider implementing these preventive measures:
- Regular Maintenance: Schedule regular check-ups to ensure your cooling system is functioning properly.
- Coolant Flush: Perform a coolant flush as recommended by your vehicle's manufacturer to keep the system clean.
- Monitor Temperature Gauge: Keep an eye on your temperature gauge while driving to catch any issues early.
- Inspect Hoses and Belts: Regularly check for wear and tear on hoses and belts that could affect the cooling system.
By following these preventive measures, you can help ensure that your Subaru remains in good working condition and avoid the stress of overheating while driving.

If you are driving and your engine begins to overheat, take the following steps:
- Turn off the air conditioning.
- Crank the heater and fan up to full blast.
- Top off the coolant cooling system with antifreeze or water.
- Rev it up.
- Pull over.
- Be prepared.
- Check coolant level.
- Watch your temperature gauge.
How does a car act when the thermostat is bad?
You Notice Erratic Temperature Changes
If you notice sudden and erratic temperature changes from cold to hot or hot to cold, then it could be a sign that your thermostat has stopped working correctly. Get your vehicle inspected if you notice these extreme temperature changes in your vehicle interior.
Why does my car overheat while driving but not at idle?
Car overheats when driving but not when idling
When you drive aggressively, or on the freeway, or up a hill, the engine needs to work harder. If your temperature gauge is fine until you make the car work, the most likely issue is coolant flow.
How do you fix a car that overheats while driving?
If your vehicle overheats in normal weather and traffic, you may need to add liquid to the system, replace the thermostat, adjust or replace the accessory belt, or check the water pump.
Why is my Subaru overheating when driving?
If your Subaru is overheating, there's a good chance the radiator may be involved. It may have a leak or be clogged, or the fan itself might be broken. If you've been in a fender bender, the radiator might have physical damage that causes it to work less effectively.
Are subarus prone to overheating?
If your Subaru overheats, you're not alone. While Subaru has a long history of making sturdy, reliable vehicles, the head gasket on some models is a weak spot. The most commonly effected Subarus are Impreza, Legacy, and Outback models produced between 1999 and 2004.
How do I know if my Subaru thermostat is bad?
Strange Sounds and Temperature Changes
You may hear rumbling, boiling, or knocking coming from the radiator. All these signs point to an issue with your car's cooling system. The thermostat also affects the temperature of air that flows in your vehicle through the vents.
What would cause car to overheat only while driving?
- Coolant Levels : Low coolant levels can lead to overheating.
- Cooling System Issues : The cooling system may have a leak, or there could be a blockage in the radiator or hoses that prevents proper coolant flow.
- Thermostat Failure
- Radiator Fan Malfunction
- Water Pump Failure
- Idle Speed
- Engine Oil
- Blocked Exhaust
