CRP EPT0126 Engine Coolant Expansion Tank

The CRP EPT0126 is an OE-quality engine coolant expansion tank manufactured under the Rein Automotive brand. This expansion tank serves as the reservoir that holds excess coolant until needed by the engine, allowing for proper expansion and contraction of coolant as it heats up and cools down during normal operation.

Key Features:

• Manufactured from virgin plastic with no regrind material to prevent cracking from heat cycles
• Engineered to meet or exceed original equipment specifications in materials and tolerances
• Direct fit replacement allowing easy installation
• Designed to match OE fit, form, and function
• Durable construction withstands underhood heat and vibration for long service life
• 2-year or 24,000-mile warranty coverage

Rein Automotive expansion tanks are positioned at the highest point in the cooling system to allow trapped air to escape while preventing air from entering when adding coolant. This design helps maintain proper cooling system pressure and prevents engine overheating. The tank replaces Mercedes-Benz OE number 1665000049 and is compatible with various ML-Class, GL-Class, GLE-Class, and GLS-Class vehicles.
