Detailed Product Description

The Rein EPT0003 engine coolant reservoir is an OE quality expansion tank built to withstand the thermal stresses typical in Mercedes-Benz performance and luxury vehicles. Its construction from high-grade virgin plastic provides resistance to cracking and degradation from heat cycling, which helps maintain coolant integrity and system pressure. The reservoir’s dimensions (16.14 inches height, 10.23 inches length, and 6.88 inches width) and weight (2.205 lbs) are optimized for a direct replacement fit, eliminating the need for modifications. This component supports the cooling system by safely storing excess coolant and allowing for thermal expansion, which is critical for maintaining engine temperature stability in models such as the CL63 AMG and S550.

Common Issues Addressed by This Coolant Reservoir

• Cracked or leaking expansion tanks causing coolant loss
• Coolant overflow due to damaged or worn reservoirs
• Heat-related wear leading to premature reservoir failure
• Improper fitment causing coolant system pressure issues
• Degraded plastic components affecting coolant containment
