It is molded to a fixed shape rather than flexible tubing, so it seats correctly on the housing and manifold fittings without kinking or requiring extra clamps to hold its form. The hose is built from a plastic and rubber material and is finished in white.\u003c\/p\u003e\u003cp\u003eThis is the PORT side hose only. The equivalent hose for the starboard side thermostat housing to exhaust manifold connection is a separate part, 18-70939, which replaces a different OEM number -- be sure to order the correct side for your engine.\u003c\/p\u003e\u003cp\u003eFitment covers 262 Mag with VST (1996-97), 4.3L-LX (1993-96) Design III, 5.0L-LX (1988-95) Design III, 350Mag-EFI-MPI (1987-96), and 5.7L-LX (1988-96) Design III Mercruiser engines. Each package includes one molded hose. Sierra manufactures this hose to meet or exceed the specifications of the original equipment part it replaces, making it a direct aftermarket replacement rather than a universal-fit substitute.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-70938\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Molded Hose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Thermostat housing to port exhaust manifold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic, Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Molded Hose (1 per package)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.71 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282227678\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 32-8066351\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e262 Mag with VST (1996-97)\u003c\/li\u003e\n\u003cli\u003e4.3L-LX (1993-96) Design III\u003c\/li\u003e\n\u003cli\u003e5.0L-LX (1988-95) Design III\u003c\/li\u003e\n\u003cli\u003e350Mag-EFI-MPI (1987-96)\u003c\/li\u003e\n\u003cli\u003e5.7L-LX (1988-96) Design III\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e32-8066351\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhich side does the 18-70938 hose fit?\u003c\/strong\u003e The 18-70938 molded hose is for the port side only, connecting the thermostat housing to the port exhaust manifold.
