Gates 17129894783 Premium Molded Radiator Coolant Hose

The Gates 17129894783 is a premium molded radiator coolant hose engineered as a direct OE replacement. Gates factory-molds this hose to exact fit and geometry specifications, ensuring proper routing, secure sealing, and reliable coolant flow between the radiator and engine cooling circuit.

Gates coolant hoses are constructed with an EPDM inner tube, synthetic fiber knit reinforcement, and an EPDM outer cover, delivering outstanding resistance to heat, ozone, and vacuum collapse. A key engineering focus is resistance to electrochemical degradation (ECD) — the leading cause of coolant hose failure — which attacks the hose from the inside out over time.

Key Features:

• Factory-molded OE replacement design for precise fit and routing
• EPDM tube and cover construction for long service life
• Engineered to resist electrochemical degradation (ECD)
• Resists vacuum collapse, heat, and ozone deterioration
• Temperature rated from -40°F to +275°F (-40°C to +135°C)
• Meets SAE 20R4 EC Class D1 standard
• OEM cross-reference: BMW Part Number 17-12-9-894-783

Replacing worn or aging coolant hoses at the first sign of cracking, swelling, or softness is critical to preventing overheating and costly engine damage. The Gates 17129894783 restores full cooling system integrity with a confident, leak-free fit.
