• Heat-related hose softening or swelling
• Restricted coolant flow between the engine and heater valve
• Loss of heater performance caused by hose deterioration
• Service replacement for aging BMW E36 cooling hoses

Installation Notes and Tips

Verify the hose routing, length, and rear left placement before installation. Compare the removed hose to Febi 37374 to confirm the 285 mm dimension and engine-to-heater-valve direction. Inspect adjoining clamps, fittings, and nearby cooling components for wear or residue before reassembly.

Quality Assurance

Febi supplies replacement parts for European vehicle service, and this hose uses EPDM material selected for coolant-system use. Confirm fitment against the vehicle’s model year and hose routing before ordering.
