Womala Lower Radiator Hose OE 1265012582 for Mercedes W126 380SE 500SE Engine Cooling System Parts
The Lower Radiator Hose (OE: 1265012582) is a critical cooling system component for specific Mercedes W126 models (380SE, 500SE). Installed in the engine cooling circuit, it facilitates the circulation of coolant between the radiator and engine, ensuring optimal heat dissipation and preventing engine overheating. As an OE-grade part, it meets Mercedes’ strict standards for heat resistance, pressure tolerance, and structural durability, ensuring seamless integration with the cooling system and reliable operation across diverse conditions (e.g., high-load driving, extreme ambient temperatures).
Constructed from high-performance materials: the hose body uses heat-resistant and pressure-resistant rubber (to withstand coolant temperature and system pressure), while the connection ends feature reinforced structures to prevent loosening or cracking, ensuring coolant tightness and long service life.
Core Functions
- Coolant Circulation: The primary function is to channel coolant from the radiator to the engine, enabling efficient heat exchange and maintaining optimal engine operating temperature.
- Overheating Prevention: Ensures consistent coolant flow to dissipate engine heat, preventing overheating and related component damage (e.g., cylinder head warping, piston seizure).
- Cooling System Integrity: Maintains a sealed coolant circuit, preventing coolant leakage and ensuring the cooling system operates at peak efficiency.

Notes: This Lower Radiator Hose is model-specific—it is tailored for Mercedes W126 380SE and 500SE models. Confirm the exact vehicle model via the VIN or Mercedes’ official parts catalog to avoid fitment errors (e.g., coolant leakage, overheating). During installation, ensure tight connection with radiator and engine interfaces to prevent coolant leakage. Regularly inspect for signs of failure (e.g., hose cracking, bulging, coolant seepage) and replace the hose immediately if faults are detected to maintain normal cooling system operation.
