Product Description

The Arrowhead Expansion Tank is a vital component in your Chevrolet's cooling system, designed to store excess coolant and maintain optimal engine temperature. This cooling water bottle is constructed from durable, translucent plastic, allowing for easy monitoring of coolant levels. Its integrated mounting tabs and hose connections ensure a secure and proper fit in your vehicle's engine bay.

This expansion tank is specifically compatible with Chevrolet models, including the Sonic 1.3D, 1.4, 1.4T RS, and 1.6 from 2011 onwards. It is important to confirm your vehicle's model, year, engine size, and engine code to ensure correct fitment before ordering.

Typical signs of a failing expansion tank include visible coolant leaks, frequent low coolant warnings, overheating, steam from under the bonnet, or cracks in the reservoir. You might also notice discoloured coolant or an engine temperature gauge reading higher than normal.

If you detect any of these symptoms, it is advisable to inspect and replace the expansion tank promptly to prevent further engine damage. Always ensure the cooling system is depressurised and cool before attempting any maintenance.
