URO URO-015461 Engine Coolant Expansion Tank

The URO URO-015461 engine coolant expansion tank is a quality aftermarket replacement for Audi vehicles, designed to restore proper cooling system function and prevent overheating. This expansion tank serves as the reservoir that holds excess coolant and allows for the thermal expansion and contraction of coolant as it heats up and cools down during engine operation.

Key Features:

• Precision-molded to OE dimensions for direct replacement fitment
• Compatible with original coolant level sensors and hose connections
• Manufactured by APA Industries with extensive quality and lifecycle testing
• Heat-resistant materials designed to withstand engine compartment temperatures
• OEM part number cross-reference: 420121403

The expansion tank is typically positioned at the highest point in the cooling system, allowing trapped air to escape and enabling proper coolant circulation without air pockets. A failed expansion tank can result in coolant leaks, loss of system pressure, reduced coolant boiling point, and potential engine overheating. URO Parts are engineered to meet or exceed OEM specifications, providing a cost-effective alternative to dealer-priced genuine parts.

Note: Cap sold separately. Fluid level sensor may be included depending on application.
