Newer heavy-duty engines with advanced emissions systems (from 2007 to current model year) produce higher under-hood temperatures, requiring the use of silicone coolant hose. In these new low engine-air-flow and high-heat conditions, Gates Silicone Coolant Hose is the perfect product.

• Premium 4-ply construction
• High-heat resistance material meets or exceeds OE specifications
• Several layers of high-quality silicone
• Blue lid and industry-standard orange tube for easy identification
• Polyester braiding, which is unaffected by refrigerant penetration and heat
• The very thick and flexible tube prevents "cold leaks" and hardening caused by heat.
