Rein EPT0132 Engine Coolant Reservoir - Radiator

OE Quality Coolant Reservoir for Mercedes-Benz

The Rein EPT0132 engine coolant reservoir is an OE-quality expansion tank built for Mercedes-Benz cooling systems that use a capless reservoir design. It is produced from virgin plastic to help resist heat-cycle cracking and maintain stable coolant storage over time.

For Mercedes-Benz AMG GT 43, AMG GT 53, C300, E350, GLC300, and related applications, this reservoir is made to match factory fitment and material expectations. The Rein EPT0132 focuses on direct replacement performance for vehicles that need a radiator-mounted or engine-bay expansion tank without a cap.

Key Features

• Produced from virgin plastic meeting or exceeding OE material specifications
• Resists cracking and wear caused by repeated heat cycles
• Direct-fit design supports straightforward replacement
• Manufactured to strict engineering standards for material and dimensional accuracy
• Built for long service life in Mercedes-Benz cooling systems

Detailed Product Overview

The Rein OE quality expansion tank is designed for drivers and technicians replacing a leaking, brittle, or heat-damaged coolant reservoir. By using virgin plastic with no regrind content, the tank is engineered to better withstand thermal stress and reduce the risk of coolant loss from cracking. This makes the Rein EPT0132 a practical replacement for Mercedes-Benz models including AMG GT 43, AMG GT 53, C43 AMG, E350, E450, E53 AMG, GLC300, and C300 applications across multiple model years.

This part cross-references URO 2055000049 for the same application.

Common Problems This Part Addresses

• Coolant leaks from a cracked or brittle expansion tank
• Low coolant warnings caused by reservoir failure
• Heat-cycle damage in aging plastic cooling components
• Loss of coolant storage capacity from damaged tank walls
• Fitment issues from using a non-OE-style replacement reservoir
