Rein 17-12-7-531-581 Lower Radiator Coolant Hose with Temperature Sensor Fitting

The Rein 17-12-7-531-581 is an OE-quality lower radiator coolant hose designed for BMW vehicles, connecting the radiator to the thermostat housing. This precision-engineered hose is manufactured from specially formulated EPDM rubber that provides superior heat resistance, contamination resistance, and long service life in demanding cooling system applications.

Key Features:

• Features integrated fitting for temperature sensor (sensor not included)
• Direct replacement for OEM part number 17127531581
• Molded EPDM rubber construction for durability and heat resistance
• Includes proper diameter, bends, and lengths for exact fit
• Built-in connectors for secure, leak-free installation
• Designed to withstand extreme temperature fluctuations and coolant exposure

This lower radiator hose is engineered to match the original manufacturer's specifications, from the size and shape of its branches to the thermoplastic quick-connect fittings. Over time, exposure to hot coolant can cause rubber hoses to split, swell, crack, or break. Replace this critical cooling system component at the first sign of wear to prevent coolant loss and potential engine overheating.
