Gates 18038 Molded Heater Hose

The Gates 18038 is a precision-molded heater hose engineered to deliver reliable coolant flow between the engine and heater core. Designed to match the exact shape and dimensions of the original equipment hose, this molded hose eliminates the need for cutting, bending, or using additional adapters during installation — ensuring a clean, leak-free fit right out of the box.

Gates manufactures this hose using high-quality EPDM (Ethylene Propylene Diene Monomer) rubber, which provides excellent resistance to heat, ozone, and coolant chemicals. The molded construction maintains its shape under pressure and temperature cycling, reducing the risk of kinking or collapsing that can restrict coolant flow and lead to overheating.

Key Features:

• Pre-molded design for precise OE-style fitment
• EPDM rubber construction for superior heat and chemical resistance
• Resists cracking, swelling, and deterioration from engine coolants
• Maintains shape under high-pressure and high-temperature conditions
• Direct replacement for OEM heater hose — no cutting or trimming required
• Alternate/OEM Part Number: 10038
