URO 11537591889PRM Engine Coolant Hose - Thermostat To Cylinder Head

BMW X3/X4 Coolant Hose Upgrade

The URO 11537591889PRM engine coolant hose is a direct-fit replacement for the thermostat to cylinder head connection on select BMW X3 and BMW X4 models. It uses an HD aluminum connector instead of the OEM plastic connector to address a common heat-cycle failure point.

Built with EPDM synthetic rubber and molded to the OE hose shape, this URO Premium hose is made for accurate fitment on BMW cooling system repairs. The 11537591889PRM part number identifies the premium re-engineered version of this application.

Key Features

• HD aluminum connector replaces the OEM plastic connector
• EPDM synthetic rubber resists engine heat, ozone, and electrochemical degradation
• Molded to OE coolant hose shape for proper routing and fit
• Temperature rated from -40°F to 275°F (-40°C to 135°C)
• URO Premium line with PRM suffix for upgraded construction
• Limited Lifetime Unlimited Mileage Warranty

Detailed Description

This coolant hose is engineered for the thermostat to cylinder head position on BMW cooling systems where the original plastic connector can become brittle and crack after repeated heat cycles. The aluminum connector and ECD-resistant EPDM construction are selected to improve durability in high-temperature engine environments. The 11537591889PRM is a practical replacement for BMW X3 and BMW X4 owners looking for a hose assembly that follows the OE shape while addressing a known weak point in the original design.

URO Premium products are re-engineered replacement parts built with stronger materials or revised designs to improve reliability over standard OE-style components. This part cross-references URO-014180 for the same application.

What It Helps Fix

• Coolant leaks at the thermostat to cylinder head hose connection
• Cracked or brittle OEM plastic connector
• Heat-cycle related hose failure
• Rubber breakdown from electrolysis or electrochemical degradation
• Fitment issues caused by non-molded replacement hoses

Installation Notes

Verify the thermostat to cylinder head routing before installation and compare the connector style to the original part. This hose is listed for 2011-2016 BMW X3, 2017 BMW X3, 2015-2016 BMW X4, 2017 BMW X4, and 2018 BMW X4 applications.
