FAQs

What is the main function of a coolant expansion tank?

The expansion tank holds excess coolant that expands when the engine heats up and returns it as the engine cools, maintaining proper system pressure and preventing coolant loss.

How do I know if my expansion tank needs replacing?

Symptoms include visible cracks or leaks on the tank, a consistently low coolant level, coolant smells, or engine overheating. White, chalky residue around the tank also indicates a leak.

Is this expansion tank compatible with my specific BMW E90 model?

This part is compatible with BMW 3 Series E90, E91, E92, and E93 models from 2005 onwards. Please verify your exact model and year against the detailed compatibility list.

What coolant should I use?

Always use the BMW-approved coolant type for your vehicle. Refer to your owner's manual for the specific designation and recommended mixture ratio with water.

Can I replace the expansion tank myself?

Replacement is possible for individuals with basic mechanical skills and the right tools. However, if you are unsure, it is recommended to have a qualified mechanic perform the installation.

What is the OE number for this part?

This part corresponds to OE numbers 17137640514 and 7640514.

Will this part affect my car's performance?

No, this expansion tank is designed to match the original part's performance and quality, ensuring your cooling system functions as intended.

Troubleshooting

Coolant leaking from the expansion tank

Inspect the tank for cracks or damage. Check hose connections for tightness and integrity. If the tank itself is damaged, it needs replacement.

Coolant level dropping continuously

Check the expansion tank, all hoses, the radiator, and the water pump for leaks. A faulty expansion tank can be a source of such leaks.

Engine overheating

Ensure the coolant level is correct and the system is properly bled. Check the expansion tank for leaks or damage, and verify the radiator cap is holding pressure.

White residue or staining around the tank

This often indicates a slow leak. Clean the area and monitor closely. If residue reappears, the tank or its seals may be compromised.
