A failed element means hard cold starts and cold-start white smoke, and on the 6.7L the grid-heater bolt is a known failure and safety concern. A correct grid-heater element and hardware restore dependable cold starting.\u003c\/p\u003e\u003ch4\u003eWhat's Included\u003c\/h4\u003e\u003cul\u003e\u003cli\u003ea grid-heater element or grid-heater hardware as specified\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eFitment\u003c\/h4\u003e\u003cp\u003eFits Chevrolet, GMC trucks equipped with the LB7 Duramax diesel engine, 1999-2003.
