I recently noticed my Toyota Camry’s temperature gauge spiking during a long drive, and a friend suggested it might be air trapped in the radiator causing the issue. I’ve never done this before, so I’m curious: How do you properly release air from a Camry’s radiator to prevent overheating? Any tips would be greatly appreciated,

Releasing air from your Toyota Camry’s radiator, often referred to as “burping” the cooling system, can help prevent overheating.
Here is a step-by-step guide to help you through the process:
- Cool down: Ensure the engine is completely cool before starting. This is crucial to avoid burns from the hot coolant.
- Elevate the front: If possible, elevate the front of the car slightly. This helps air bubbles move towards the radiator cap.
- Remove the radiator cap: Open the radiator cap slowly to release any built-up pressure.
- Fill the radiator: Fill the radiator with a 50/50 mix of coolant and water until it’s full.
- Start the engine: With the radiator cap off, start the engine and let it idle. Turn the heater to the maximum setting to help circulate the coolant.
- Watch for bubbles: As the engine warms up, you should see air bubbles rising to the top of the radiator. This indicates that air is being expelled from the system.
- Squeeze the hoses: Gently squeeze the upper radiator hose to help push trapped air out
- Top off coolant: Keep an eye on the coolant level and add more if necessary. Continue this process until you no longer see air bubbles.
- Replace the radiator cap: Once the bubbles stop and the coolant level stabilizes, replace the radiator cap.
- Check the overflow tank: Make sure the overflow tank is filled to the appropriate level.
- Monitor the temperature: Keep an eye on the temperature gauge during your next few drives to ensure the issue is resolved.
Unscrew the radiator cap and pour in coolant. Keep the cap off, turn the heater to full blast, and start the car. Let it idle while you watch the coolant level go up in the radiator.
