• Coolant hose direction: from throttle body to cylinder head
• OE-style replacement for select BMW cooling layouts
• febi part number 37134

Detailed Description

febi 37134 is a radiator coolant hose engineered for BMW engines that use a throttle-body-to-cylinder-head coolant routing path. The EPDM rubber construction is suited to the temperature and fluid exposure common in engine cooling systems, while the 250 mm length supports proper routing and connection alignment. This hose is listed for 1993-1995 BMW 320i, 1996-1999 BMW 328i and 328is, 1997-1998 BMW 528i, 1997-1998 BMW Z3, and 1998-1999 BMW 323i and 323is applications. Part number 37134 also cross-references BMW OE number 13 54 1 703 865 for the same application.

What This Hose Helps Address

• Coolant leaks from a cracked or hardened hose
• Loss of proper coolant flow between the throttle body and cylinder head
• Heat-related rubber deterioration in the engine bay
• Incorrect hose routing after prior repair work
• Fitment issues caused by using a hose with the wrong length

Installation Notes and Tips

Verify the vehicle’s build date and engine configuration before ordering, especially on 1998 BMW 528i and Z3 models with fitment limited to production through 09/1998. Confirm the hose routing matches the listed direction from throttle body to cylinder head, and compare the old hose length to the 250 mm specification before installation. Inspect adjoining clamps, plastic fittings, and nearby cooling components for wear before reassembly.

Quality Assurance

febi supplies OE-style replacement parts for European vehicles, and this hose is built to match the listed BMW applications and material specification. Use the confirmed fitment data and OE cross-reference when selecting the correct replacement for your cooling system service.
