Detailed Description

Rein EPT0023 is an engine coolant reservoir designed to replace the original expansion tank on select Volvo 850, C70, S70, and V70 models. The tank is manufactured from virgin plastic with no regrind, which helps improve durability in high-temperature cooling system environments. For drivers addressing coolant reservoir leaks, brittle plastic, or age-related tank failure, this OE-style replacement restores proper coolant storage and system function.

This part cross-references Genu 9141095 for the same application.

Common Problems This Part Helps Solve

• Coolant loss from a cracked or weakened reservoir
• Visible plastic fatigue from repeated heat cycles
• Leaking expansion tank seams or housing damage
• Cooling system service needs on aging Volvo 850, C70, S70, or V70 models

Installation Notes and Tips

Verify the reservoir shape, hose connections, and mounting points against the original tank before installation. Inspect related cooling system components, including hoses, caps, and clamps, for wear or contamination while the reservoir is removed. After installation, refill and bleed the cooling system according to the vehicle service procedure to help prevent air pockets.
