When an EGR cooler cracks it dumps coolant into the intake or exhaust — white smoke, coolant loss and overheating — and a stuck valve sets flow codes. A correct OEM-style replacement restores proper EGR function and a sealed cooling system so the truck runs right and passes inspection. These are genuine OE-replacement service parts that return the emissions system to proper factory operation.\u003c\/p\u003e\u003ch4\u003eWhat's Included\u003c\/h4\u003e\u003cul\u003e\u003cli\u003ea replacement EGR cooler, valve or gasket built to restore OE function\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eFitment\u003c\/h4\u003e\u003cp\u003eFits Chevrolet, GMC trucks equipped with the LLY Duramax diesel engine, 2004.5-2005.
