Product Details
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.

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.
Frequently Asked Questions
