Is your Mercedes coolant cap leaking or not holding pressure?

This 2-pack of replacement caps is a direct fit for OE part #2105010615, designed for dozens of Mercedes models including C-Class, E-Class, CLK, ML, SLK, and more (see full list in description).

Made from high-temperature resistant materials, it maintains a tight seal to keep your cooling system running efficiently.

A worn cap can cause overheating, coolant loss, or poor heater performance.

Swapping it out is a quick, affordable fix that can prevent bigger problems down the road.

Each cap is built to withstand engine heat and vibration for long-lasting reliability.

Always check your vehicle’s specific year and model before ordering.

Keep a spare on hand – with two caps in the pack, you’ve got an extra for future use or another vehicle.
