Its corrosion-resistant bullet terminal and steel housing are designed to maintain conductivity where the heater seats in the air intake assembly. This part cross-references ACDelco 98050454 for the same application.\u003c\/p\u003e\u003cp\u003eCompatible With 2007-2010 Chevrolet Silverado 2500 HD and Silverado 3500 HD, as well as 2007-2010 GMC Sierra 2500 HD and Sierra 3500 HD, this DIH7 intake heater is a direct-fit service part for diesel intake heater repair on LMM-equipped trucks. The Standard Ignition DIH7 part number is also a useful reference when verifying the correct diesel air intake heater for these GM HD applications.\u003c\/p\u003e\u003ch2\u003eCommon Issues It May Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHard starting during cold weather\u003c\/li\u003e\n\u003cli\u003eExcess white smoke at initial start-up\u003c\/li\u003e\n\u003cli\u003eWeak or inconsistent intake heater operation\u003c\/li\u003e\n\u003cli\u003eCorrosion at the heater connection or ground point\u003c\/li\u003e\n\u003cli\u003eFaults related to the diesel intake air heater circuit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eConfirm the engine ID code LMM and 12-volt electrical system before ordering. Inspect the intake housing, relay circuit, and connector terminals for corrosion or heat damage before installing the new heater. Verify the square female connector and 6-pin terminal layout match the original part, and ensure the heater seats cleanly in the air intake housing for proper grounding.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eStandard Ignition states that this intake heater is built to OE specification and tested at the end of the production line for consistent out-of-box performance.
