URO 11537603514PRM Engine Coolant Hose - Thermostat Housing To Engine

BMW Coolant Hose Upgrade

This URO engine coolant hose is built for BMW cooling systems that use a thermostat housing to engine routing. It replaces the factory plastic connector with a metal connector and EPDM synthetic rubber construction for improved durability in demanding heat cycles.

Compatible with select 2012-2018 BMW 228i, 320i, 328i, 428i, 528i, X1, X3, X4, X5, Z4, and related xDrive and Gran Coupe applications, this part number 11537603514PRM is a direct-fit cooling system service part for the listed vehicles.

Key Features

• HD aluminum connector replaces the OEM plastic connector
• EPDM synthetic rubber construction for heat and ozone resistance
• ECD-resistant material helps reduce internal rubber breakdown from electrolysis
• Molded to OE coolant hose shape for fitment on the listed BMW applications
• Temperature rating from -40°F to 275°F (-40°C to 135°C)
• URO Premium line with PRM suffix for upgraded replacement parts
• Limited lifetime unlimited mileage warranty

Product Details

The URO 11537603514PRM coolant hose is engineered for BMW cooling system service where the thermostat housing to engine hose connection is a known failure point. The upgraded metal connector addresses the brittleness commonly seen in plastic connectors after repeated heat cycling, while the EPDM hose material is selected to resist engine heat, ozone exposure, and electrochemical degradation. This makes it a practical replacement for BMW 320i, 328i, 528i, X3, X5, and other listed models that require this OE-shaped hose assembly.

This part cross-references VAICO V20-2893 for the same application.

What It Helps Fix

• Coolant leaks at the thermostat housing to engine hose connection
• Cracked or broken OEM plastic connector
• Hose deterioration from heat cycling and ozone exposure
• Internal rubber breakdown caused by electrolysis
• Cooling system service needs on BMW turbo and non-turbo applications listed above

Installation Notes

Install on a cool engine and drain coolant before removing the existing hose. Inspect the thermostat housing, engine connection points, and adjacent cooling components for wear, residue, or damage before assembly. Confirm the hose routing matches the OE layout for the specific BMW model and year before final tightening and refill.

Quality Assurance

URO Premium parts are re-engineered with more robust materials and design changes to address failure-prone OE components. Part number 11537603514PRM includes a limited lifetime unlimited mileage warranty.
