Over time, the internal damping spring within the stock tensioner assembly fatigues, leading to tensioner arm oscillation, premature belt wear, and belt slippage under heavy load from the high-output alternator. Concurrently, factory idler pulley bearings dry out, seize, or create rotational play. On the 5.3L \u003cstrong\u003eLM7\u003c\/strong\u003e Vortec V8, belt deflection can result in thrown belts, dead batteries, loss of power steering, and immediate water pump failure.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive service kit restores the accessory drive system to reliable operating standards. The heavy-duty cast tensioner assembly (\u003cstrong\u003e38158\u003c\/strong\u003e) utilizes an engineered internal spring to maintain constant mechanical pressure across all engine speeds. Matched with a precision-ground, high-grade steel idler pulley (\u003cstrong\u003e38001\u003c\/strong\u003e) with sealed bearings, parasitic drag and torsional harmonic transfer are drastically reduced. The package is completed with an EPDM multi-rib serpentine belt (\u003cstrong\u003e6PK2360\u003c\/strong\u003e) formulated to withstand high ambient under-hood temperatures without cracking or glazing.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Serpentine Belt (Part # 6PK2360)\u003c\/li\u003e\n  \u003cli\u003e1 Idler Pulley (Part # 38001)\u003c\/li\u003e\n  \u003cli\u003e1 Tensioner Assembly (Part # 38158)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2000-2002 GMC Yukon\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e5.3L LM7 Vortec \/ GMT800\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e285 hp \/ 325 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e6PK2360, 38001, 38158\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2000 GMC Yukon 5.3L V8 (130 Amp Alternator Option)\u003c\/li\u003e\n  \u003cli\u003e2001 GMC Yukon 5.3L V8 (130 Amp Alternator Option)\u003c\/li\u003e\n  \u003cli\u003e2002 GMC Yukon 5.3L V8 (130 Amp Alternator Option)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the GMT800 Yukon?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2000-2002 GMC Yukon equipped with the \u003cstrong\u003eLM7\u003c\/strong\u003e 5.3L V8 engine. \u003cstrong\u003eDoes not fit models equipped with the standard 105 Amp alternator option, which requires a shorter belt length.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eHow do I verify if I have the 130 Amp alternator?\u003c\/h4\u003e\n\u003cp\u003eCheck the glove box RPO code sticker for option code KG8 (130 Amp), or measure the pulley-to-pulley belt length matching the 2360mm specification before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eThe GMC Heavy-Duty Caliber\u003c\/h3\u003e\n\u003cp\u003eFull-size GM platforms rely on continuous accessory performance for heavy towing, cooling, and demanding payload cycles.
