This guide will provide a step-by-step walkthrough on how to remove the coolant reservoir from a Mazda 3.
Materials You’ll Need
- Socket wrench or adjustable wrench
- Phillips screwdriver
- Drain pan
- Clean rags
- New coolant reservoir (if replacing)

Step-by-Step Instructions
1. Locate the Coolant Reservoir
The coolant reservoir is typically located in the engine bay near the radiator. It’s a plastic tank with a cap and a level indicator.
2. Drain the Coolant
Place a drain pan under the coolant reservoir. Using a socket wrench or adjustable wrench, loosen the drain plug at the bottom of the reservoir. Allow the coolant to drain into the pan.
3. Disconnect the Hoses
Once the coolant has drained, use a Phillips screwdriver to loosen the hose clamps on the hoses connected to the reservoir. Gently pull the hoses off the reservoir.
4. Remove the Mounting Bolts
There are usually two or three mounting bolts holding the reservoir in place. Use a socket wrench or adjustable wrench to loosen and remove these bolts.
5. Lift Out the Reservoir
Carefully lift the coolant reservoir out of the engine bay. Be cautious not to spill any remaining coolant.
6. Clean the Mounting Surface
Clean the mounting surface where the coolant reservoir was located using a clean rag. This will ensure a proper seal when reinstalling the new reservoir.
7. Install the New Reservoir (Optional)
If you’re replacing the coolant reservoir, insert the new reservoir into the mounting surface and align it with the mounting bolts. Tighten the bolts securely.
8. Reconnect the Hoses
Slide the hoses onto the new reservoir and tighten the hose clamps using a Phillips screwdriver.
9. Add New Coolant
Use a funnel to fill the new coolant reservoir with the appropriate coolant for your Mazda 3. Refer to your owner’s manual for the recommended coolant type and capacity.
10. Check for Leaks
Start the engine and let it run for a few minutes. Check for any leaks around the coolant reservoir and hoses. If you notice any leaks, tighten the connections or replace the faulty components.
Tips
- Use a new O-ring on the drain plug when reinstalling it.
- If the coolant is dirty or discolored, it’s recommended to flush the entire cooling system.
- Check the coolant level regularly and top it up as needed.
Final Thoughts
Removing the coolant reservoir from a Mazda 3 is a simple process that can be completed in under an hour. By following these steps and taking necessary precautions, you can effectively maintain your vehicle’s cooling system and ensure its optimal performance.
