OE-Style Radiator Hose for BMW Cooling Repair

Rein CHR0070R is a direct-fit radiator coolant hose for select BMW cooling system applications. Built to OE dimensions and formed for the lower radiator-to-thermostat route, it supports a clean replacement on 1996-1999 BMW 318i, 318is, 318ti, and 1996-1998 BMW Z3 models.

Designed for European vehicle cooling systems, this hose uses EPDM construction and thermoplastic quick-connect style fitment details to match the original layout. The result is a replacement that reduces installation time and helps restore a secure, leak-resistant connection.

Key Features

  • Direct replacement radiator coolant hose for OE-style service
  • Fits the lower radiator to thermostat position on listed BMW applications
  • EPDM hose material with resistance to heat, salt, road debris, oil, and contaminants
  • SAE J20 R4 D1 construction standard
  • Maximum working pressure: 130 psi
  • Black finish with application-specific dimensions for proper routing
  • Rein part number CHR0070R for easy identification

Detailed Description

Rein CHR0070R is engineered as a complete OE quality direct-fit radiator hose for European vehicles. It is shaped to match the original hose geometry, including branch size and connector style, so it installs without cutting, refitting, or adjusting the hose. This helps maintain the factory cooling system layout on BMW 318i, BMW 318is, BMW 318ti, and BMW Z3 models.

This radiator coolant hose is built from EPDM and measures 13 inches centerline length, with hose end diameters sized for the specified application. It is a practical choice for replacing a worn lower radiator hose on 1996-1999 BMW 318i, 1996-1999 BMW 318is, 1996-1999 BMW 318ti, and 1996-1998 BMW Z3 vehicles.

This part cross-references URO 11531247261 for the same application.

What It Helps Fix

  • Coolant leaks from a cracked, hardened, or swollen lower radiator hose
  • Poor sealing caused by worn quick connectors or aged O-rings
  • Cooling system service delays from hose trimming or rework
  • Fitment issues when replacing an OE-style BMW radiator hose
  • Heat and contamination-related hose deterioration

Installation Notes and Tips

Verify the lower radiator-to-thermostat routing before installation and compare the hose shape to the removed part. Inspect mating surfaces, quick connectors, and O-rings for wear before assembly. Because this hose is application-specific, it is designed to install without cutting or reshaping.

For best results, flush and refill the cooling system according to the vehicle service procedure after hose replacement. Confirm clamp and connector engagement before returning the vehicle to service.

Quality Assurance

Rein positions this hose as an OE quality replacement for European vehicles, with dimensions and connector details matched to the original design. It is backed by a 24-month warranty with 24,000-mile coverage.
