Rein EPT0143 Engine Coolant Reservoir

OE Quality Engine Coolant Reservoir

The Rein EPT0143 engine coolant reservoir is an OE-quality expansion tank built for direct replacement on select Mercedes-Benz Sprinter and Dodge Sprinter applications. It is made from virgin plastic to help maintain durability through repeated heat cycles and reduce the risk of cracking that can lead to coolant loss.

Compatible with 2007-2009 Dodge Sprinter 2500, 2007-2009 Dodge Sprinter 3500, 2010-2018 Mercedes-Benz Sprinter 2500, 2010-2018 Mercedes-Benz Sprinter 3500, 2014-2017 Mercedes-Benz Sprinter, and 2018 Mercedes-Benz Sprinter 3500XD.

• Produced from virgin plastic meeting or exceeding OE material specifications
• Resists cracking and wear from heat cycling
• Direct-fit design supports straightforward installation
• Built to strict engineering standards for material quality and tolerances
• OE-style replacement for cooling system service on Sprinter vans

Detailed Product Overview

Rein EPT0143 is an OE-quality expansion tank designed to match the fit, form, and function of the original coolant reservoir. For Mercedes-Benz Sprinter 2500, Sprinter 3500, Sprinter 3500XD, and Dodge Sprinter models, this reservoir helps maintain proper coolant expansion and recovery within the cooling system. The virgin-plastic construction is selected to improve long-term durability and reduce the chance of premature failure from thermal cycling.

This part cross-references Mopar 68004910AA and URO 9065010503 for the same application.

Common Cooling System Issues Addressed

• Cracked coolant reservoir housing
• Coolant loss from heat-related plastic fatigue
• Visible reservoir aging or discoloration
• Leaks at the expansion tank body
• Replacement needs during Sprinter cooling system repair

Installation Notes and Tips

Verify the reservoir shape, hose connections, and mounting points against the original part 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.

Quality Assurance

Rein manufactures this expansion tank to OE-quality standards using virgin plastic rather than regrind material. That material choice supports durability, dimensional consistency, and long service life in demanding cooling system conditions.
