Womala Engine Coolant Recovery Tank Hose OE A1645000075 for Mercedes
The Engine Coolant Recovery Tank Hose (OE: A1645000075) is a key fluid transmission component of the cooling system for Mercedes Benz ML and GL series models. Connecting the engine coolant recovery tank (expansion tank) to the radiator or engine, it facilitates the circulation and replenishment of coolant. As an OE-grade part, it meets Mercedes’ strict standards for high-temperature resistance, pressure bearing capacity, and leak-proof performance, ensuring reliable operation across conditions (e.g., engine heating/cooling cycles, high-load driving, extreme temperature fluctuations).
Constructed from high-performance materials: the hose uses heat-resistant and corrosion-resistant rubber (to withstand high-temperature coolant and engine bay heat without aging or cracking) with reinforced fiber layers. This design enhances structural stability and shape retention, while precision-molded interfaces ensure a tight seal with the recovery tank and adjacent components.
Core Functions
Coolant Circulation & Replenishment: Guides expanded coolant from the engine/radiator to the recovery tank during heating, and returns coolant to the system during cooling to maintain stable fluid volume.
Pressure Adaptation: Withstands the pressure changes of the cooling system during thermal cycles, avoiding hose burst or deformation.
Leak-Proof Protection: High-quality rubber material and tight interfaces prevent coolant leakage, ensuring the cooling system’s efficiency and avoiding engine overheating risks.
Compatible Vehicles
This Engine Coolant Recovery Tank Hose is tailored for the following Mercedes models and its respective OE number:

Notes: This Engine Coolant Recovery Tank Hose is model-specific and designed exclusively for the listed Mercedes ML and GL series models. Do not use it for other models or variants to avoid mismatched connections, insufficient pressure resistance, or coolant leakage. During installation, ensure the hose is routed correctly (avoiding kinks or contact with high-temperature components) and secured with original clamps. Use only Mercedes-approved coolant. Periodically check for hose aging, cracks, bulges, or leakage, and replace immediately if faulty to maintain the cooling system’s normal operation and protect the engine from overheating.
