OE Water Hose for BMW Cooling System Service

Rein CHE0629 is an OE-quality engine coolant hose for BMW cooling system repairs. It is built as a direct replacement for the original hose assembly, with the correct branch shape and thermoplastic quick-connect fittings for a precise service fit on BMW X1, 135i, 135is, 335i, and 335i xDrive applications.

Key Features

  • Direct OE-style replacement for the thermostat to cylinder head coolant hose
  • Reduces installation time during cooling system repair
  • No cutting, refitting, or adjusting the hose during installation
  • Helps prevent leaks and repeat repairs from reused quick connectors and O-rings
  • EPDM hose construction resists heat, salt, road debris, oil, and other contaminants
  • Black single-hose design with application-specific dimensions

Detailed Description

Rein CHE0629 is engineered for BMW cooling system service where the thermostat to cylinder head hose must match the original routing and connection style. The hose measures 20.0 inches centerline length and uses EPDM material for durability in high-temperature engine bay conditions. Its OE-matched shape and quick-connect design support a clean replacement on 2011-2013 BMW 135i, 2013 BMW 135is, 2011-2013 BMW 335i, 2011-2013 BMW 335i xDrive, and 2013-2015 BMW X1 models. This part cross-references Genuine 11537584549 for the same application. CHE0629 is a practical choice when replacing a worn BMW coolant hose and restoring proper coolant flow.

What This Hose Helps Address

  • Coolant leaks at the thermostat to cylinder head hose connection
  • Cracked, swollen, or heat-aged coolant hose material
  • Fitment issues caused by non-OE hose shape or length
  • Repeat leaks from reused quick connectors or O-rings
  • Cooling system service delays from hoses that require trimming or adjustment

Installation Notes and Tips

Verify the hose routing and connector style against the removed part before installation. Inspect mating surfaces, quick connectors, and sealing points for wear or contamination, and replace damaged seals as needed. This hose is application-specific for the listed BMW models and position, so confirm the thermostat to cylinder head routing before service. Part number CHE0629 should be matched to the vehicle’s cooling system layout during diagnosis and repair.

Quality Assurance

Rein manufactures OE-quality coolant hoses for European vehicles, with replacement geometry and connector details modeled after the original equipment design. CHE0629 is built to the same general fit and function expectations as the factory hose assembly for the listed BMW applications.
