It converts coolant temperature into an electrical signal that is read by the engine's temperature gauge, giving the operator a real-time reading of engine operating temperature. The sender uses Sender Code D and is rated to an upper temperature of 240 degrees Fahrenheit, with a split temperature range for accurate mid-range readings as well as high-temperature warning detection.\u003c\/p\u003e\u003cp\u003eIt threads into the engine block or cylinder head using a 3\/8 inch or 9.5mm -18 NPT thread and connects to the gauge wiring through a 10-32 stud terminal, making it a straightforward engine-mount replacement for the factory sender. As a direct fit for the original equipment part it replaces, it restores accurate temperature gauge readings without requiring changes to existing wiring or gauge hardware.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
