Detailed Product Description

This engine coolant reservoir by URO is engineered to meet the specifications of Audi A6 Quattro vehicles. Made from high-quality polypropylene, the reservoir offers resistance to heat and chemical corrosion, ensuring long-term durability. The white translucent design allows for quick visual checks of coolant levels without removing the cap.

The included mounting brackets facilitate a secure fitment in the engine bay, while the integrated level sensor supports the vehicle’s coolant monitoring system, alerting drivers to low coolant levels.

Common Applications and Issues Addressed

• Replacement for cracked or leaking coolant reservoirs

• Ensures secure mounting to avoid vibrations and leaks

Installation Notes and Tips

When installing the URO 4F0121403M engine coolant reservoir on an Audi A6 Quattro, ensure the mounting brackets align correctly with the vehicle’s frame. Since the cap is not included, retain the original pressurized cap or source a compatible replacement. Verify the level sensor connector is properly attached to maintain accurate coolant level readings. It is recommended to inspect hoses and clamps during installation to prevent future leaks.
