Mercedes-Benz C-Class W204 / GLK / E-Class - Radiator Expansion Bottle

Description

High-performance Radiator Expansion Bottle (Ref: CTM4142) engineered for the precision cooling requirements of the Mercedes-Benz C-Class and GLK platforms.

This pressurized coolant reservoir is a critical component for maintaining stable engine temperatures and managing thermal expansion. Specifically designed to match the mounting points and sensor interfaces of the W204 chassis, it is constructed from reinforced, heat-stabilized polymer to withstand the high-pressure cycles of modern European engines. Replacing an aged or cracked reservoir is essential for preventing coolant loss and protecting the engine from overheating under demanding South African operating conditions.
