Product Description

This Moca Expansion Tank is designed for the cooling system of Opel vehicles, serving as a crucial component for maintaining proper coolant levels and pressure. Constructed from durable white translucent plastic, it allows easy monitoring of coolant levels and features a circular fill opening with a secure metal rim, an angled hose connection port, and two mounting tabs for straightforward installation.

This expansion tank is specifically compatible with Opel models. It is essential to confirm your vehicle's model, year, engine size, and engine code to ensure correct fitment before ordering.

Common symptoms indicating a faulty expansion tank include frequent coolant loss, visible cracks or leaks, overheating, fluctuating temperature gauge readings, low coolant warnings, or steam from the engine bay. If you notice any of these issues, inspection and replacement of the expansion tank may be necessary.

Replacing a damaged or leaking expansion tank is important to prevent engine overheating and potential damage to other cooling system components. Always ensure the cooling system is fully depressurised and cooled before attempting removal or installation.
