URO 8K0121403Q Coolant Expansion Tank

The URO 8K0121403Q is a precision-molded polypropylene coolant expansion tank designed as a direct replacement for European vehicles. This recovery reservoir maintains proper coolant system pressure and compensates for fluid expansion during engine operation.

Key Features:

• Precision-molded to OE dimensions for guaranteed fitment with original sensors and connections
• High-quality polypropylene construction resists engine heat and harsh coolant system environment
• Factory pressure-tested to ensure leak-free performance
• ISO 9001 certified manufacturing for consistent quality
• Affordable alternative to overpriced dealership components

URO Parts has been a trusted supplier of European vehicle components for over thirty years, delivering quality replacement parts that meet or exceed original equipment specifications. Thermal cycling and age eventually cause expansion tanks to crack and fail, making timely replacement essential to prevent coolant loss and potential engine overheating.
