It mounts directly into the engine block or cylinder head to feed an analog temperature signal to the dash gauge, giving the operator a continuous, accurate read on coolant temperature so overheating can be caught before it causes engine damage.\u003c\/p\u003e\u003cp\u003eThe sender body is machined from brass for corrosion resistance in a marine environment, and the internal sensing element is rated to 260 degrees Fahrenheit with a measurement accuracy of plus or minus 1.5 percent. It uses a standard screw-in mounting type and analog output, so it is compatible with the factory temperature gauge on applicable Volvo Penta inboard applications without additional wiring or electronics. Each Sierra sender is built and tested to meet or exceed the performance of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003eThe 18-7647 is designed for use in select Volvo Penta inboard engines, including 3.0, 4.3, 5.0, and 5.7 liter GL, GLP, GLM, GSP, and GSM engine variants from model years 1998-2007. It is interchangeable with Volvo Penta 872066 and Mallory 9-42407 temperature senders, making it a direct replacement option where those part numbers are called for. Confirm the sender matches your engine model and mounting thread before ordering, since sending units vary across engine families.\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 18-7647\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 6 x 1 x 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Screw-in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Type:\u003c\/strong\u003e Analog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUpper Temperature Rating:\u003c\/strong\u003e 260 degrees Fahrenheit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Accuracy:\u003c\/strong\u003e plus or minus 1.5 percent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecific Uses For Product:\u003c\/strong\u003e Volvo Penta inboard engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Temperature Sender\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282287474\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eVolvo Penta inboard engines: 4.3Gl-a, 4.3Gl-b, 4.3Gl-c, 4.3Gl-d, 4.3Gl-e, 4.3Gl-ef, 4.3Gl-g, 4.3Gl-gf, 4.3Gl-j, 4.3Gl-jf, 5.7Gl-a, 5.7Gl-b, 5.7Gl-c, 5.7Gl-d, 5.7Gl-e, 5.0Gl-a, 5.0Gl-b, 5.0Gl-c, 5.0Gl-d, 5.0Gl-e, 5.0Gl-f, 5.0Glff, 5.0Gl-h, 5.0Gl-hf, 5.0Gl-j, 5.0Gl-jf, 3.0Glp-a, 3.0Glp-b, 3.0Glp-c, 3.0Glp-d, 3.0Glp-e, 3.0Glp-j, 3.0Glp-n, 3.0Glm-a, 3.0Glm-b, 3.0Glm-c, 3.0Gsp-a, 3.0Gsp-b, 3.0Gsp-c, 3.0Gsm-a, 3.0Gsm-b, 3.0Gsm-c (1998-2007)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eVolvo Penta 872066\u003c\/li\u003e\n\u003cli\u003eMallory 9-42407\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-7647 temperature sender fit?\u003c\/strong\u003e The 18-7647 is designed for use in select Volvo Penta inboard engines, covering 3.0, 4.3, 5.0, and 5.7 liter GL, GLP, GLM, GSP, and GSM variants built from 1998-2007.
