ProParts Coolant Expansion Tank

The ProParts Coolant Expansion Tank (also called a coolant reservoir or overflow tank) is an aftermarket replacement for Volvo cooling systems. It stores engine coolant and allows for the expansion and contraction that happens as the fluid heats up and cools down.

Key Features:

• Made from high-quality plastic that resists cracking and leaking
• Designed to meet or exceed OEM specifications for fit and function
• Keeps coolant contained so the cooling system keeps working properly
• Direct-replacement design for a straightforward installation
• Cross-referenced to the original Volvo part numbers for each variant in the line

A cracked or leaking expansion tank can cause coolant loss and overheating. Replacing it with a ProParts tank helps restore proper coolant capacity and system pressure management. Choose the specific part number in this product line to get the tank for your application.
