Rein EPT0010 Engine Coolant Reservoir

OE Quality Expansion Tank for Volvo Cooling Systems

Rein EPT0010 is an OE-quality engine coolant reservoir built for Volvo cooling system service. It is made from virgin plastic to help resist heat-cycle cracking and maintain a durable seal over long-term use. This expansion tank is a direct-fit replacement for select Volvo S90, V90, 960, 940, and 740 applications.

Key Features

• Produced from virgin plastic meeting or exceeding OE material specifications
• Resists cracking and wear caused by repeated heat cycles to help prevent coolant loss
• Direct fitment supports straightforward installation
• Manufactured to strict engineering standards for material quality and tolerances
• OE-quality replacement for Volvo cooling system repair

Detailed Description

The Rein EPT0010 expansion tank is designed for drivers and technicians replacing a worn or damaged coolant reservoir on select Volvo models. Built to match OE fit, form, and function, it helps restore proper coolant storage and pressure management in the cooling system. This part number, EPT0010, is engineered for long service life using virgin plastic rather than regrind material, which helps improve durability in high-heat engine bay conditions. It is a practical replacement for Volvo S90, Volvo V90, Volvo 960, Volvo 940, and Volvo 740 cooling system maintenance.

This part cross-references Genu 9122997 and 9122564 for the same application.

Common Issues It Can Help Address

• Coolant leaks from a cracked reservoir
• Visible plastic fatigue or heat damage on the tank body
• Loss of coolant level due to reservoir failure
• Cooling system service on aging Volvo S90, V90, 960, 940, or 740 models
• Fitment problems caused by a deteriorated OE-style expansion tank

Installation Notes and Tips

Verify the reservoir shape, hose connections, and mounting points against the original part before installation. Inspect related cooling system components such as hoses, caps, and clamps for wear while the system is open. After installation, refill and bleed the cooling system according to the vehicle service procedure to help maintain proper operation.

Quality Assurance

Rein manufactures this expansion tank to OE-quality standards using materials selected for durability and consistent fit.
