Gates 25652 Molded Coolant Hose

The Gates 25652 is a precision-molded coolant hose engineered to deliver OEM-quality fit and long-lasting performance in engine cooling system applications. Pre-shaped to match original equipment specifications, this molded radiator hose eliminates the guesswork of adaptation and ensures a leak-free, perfectly sealed connection every time.

Constructed with an EPDM tube and synthetic fiber knit reinforcement, the Gates 25652 is specifically engineered to resist electrochemical degradation (ECD) — the leading cause of coolant hose failure. Unlike standard hoses, Gates' compound resists the micro-cracking caused by the galvanic reaction between coolant fluid, metal fittings, and the hose material itself.

Key Features:

• Factory-molded for precise OEM-spec fit — no trimming or adaptation required
• EPDM construction resists heat, ozone, and chemical coolants
• Engineered to combat electrochemical degradation (ECD)
• Resists vacuum collapse without the need for internal springs
• Meets SAE 20R4 EC Class D1 standards
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Compatible with standard and extended-life coolant formulas
• Not for use with fuel or oil

Gates recommends replacing hose clamps each time a new coolant hose is installed to ensure a secure, long-lasting seal. Trust Gates — the industry leader in replacement coolant hoses — for a direct-fit solution that meets or exceeds original equipment performance.
