Product Information
Full details
The Jnchdghwa Expansion Tank (96930818) is a specialized automotive replacement component engineered specifically for Aveo LS and LT L4 model engines. It is designed for vehicle owners or mechanics looking to restore the cooling system's integrity by replacing a cracked, leaking, or yellowed reservoir, ensuring optimal coolant pressure management. While it serves as a reliable OE-equivalent replacement, users should be aware that the installation process requires a completely cooled engine to prevent severe injury from pressurized coolant.

Extended Product Information
FAQs
Is the radiator pressure cap included?
No, this part is strictly the expansion tank reservoir. You should reuse your existing cap or purchase a new one if the rubber seal is damaged.
Will this fit an Aveo with a V6 engine?
No, this part is specifically designed for Aveo LS and LT L4 (4-cylinder) models.
Why is my tank turning brown?
Over time, high heat and exposure to coolant additives cause the plastic to oxidize and become brittle, which is a common sign that the tank needs replacing to prevent a rupture.
Do I need special tools to install this?
Basic hand tools like a socket set and pliers for the hose clamps are typically all that is required for this installation.
Can I use universal coolant with this tank?
Always use the coolant type specified in your Aveo owner's manual to ensure compatibility with your vehicle's engine components and the materials of the new tank.
Troubleshooting
Coolant level drops shortly after installation
This is often due to trapped air. Ensure the cooling system is properly bled and top off coolant as the air pockets work their way out.
Tank appears to be leaking near the neck
Inspect your radiator cap; if the seal on the cap is worn, it will leak at the neck of the expansion tank regardless of how new the tank is.
Pros and Cons

- Not compatible with non-L4 engine configurations
Setup, Compatibility & Care
Before starting installation, ensure the engine is completely cold to avoid contact with pressurized, boiling coolant. To install, drain the existing coolant, disconnect the overflow hoses from the old reservoir, and unscrew the mounting bolts. Transfer any necessary hardware to the new Jnchdghwa unit, mount it in place, and securely reattach the hoses. Once installed, fill the reservoir to the 'Cold' line, run the engine with the heater on, and monitor for air bubbles to ensure the cooling system is properly bled. It is recommended to inspect the tank every oil change for signs of hairline cracks or discoloration, which signal the plastic has reached its end of service life.
