Sierra 18-70955 Molded Cooling Hose for MerCruiser V8 Engines

The Sierra 18-70955 is a precision-molded marine cooling system hose designed as a direct replacement for MerCruiser V8 stern drive engines. This hose services the oil cooler to thermostat housing connection on applications where all four hose connectors are cast directly into the thermostat housing (no "T" connector required), with two hoses routing to the manifold and two hoses to the elbow.

Key Features:

• OEM Replacement: Replaces MerCruiser OEM part number 32-16011
• EPDM Construction: Manufactured from durable EPDM tubing with synthetic knit reinforcement for long-lasting performance in harsh marine environments
• Precision Molded: Pre-formed shape ensures full water flow through every bend while simplifying installation
• OEM-Quality Standards: Engineered to meet or exceed original equipment specifications in fit, form, and function
• Fresh or Raw Water Systems: Suitable for use in both fresh water and raw water marine cooling systems

Sierra molded hoses are built to withstand the demanding conditions of marine engine cooling systems. The pre-molded design eliminates the need for cutting or shaping during installation, making this a straightforward drop-in replacement for qualified technicians and experienced boaters.
