Under heavy continuous electrical demand—such as high-wattage sound systems, auxiliary lighting, or performance cooling fans—the OEM diode bridge experiences thermal fatigue, causing line voltage to sag below 12.8 volts. This continuous thermal strain and rotor saturation degrade the internal windings, leading to premature diode burnout and sluggish electronic throttle response.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a direct bolt-in replacement, this high-output unit supplies a robust 250 amps of continuous power. Featuring heavy-gauge copper windings, premium avalanche diode rectifiers, and high-temp insulated stators, this assembly maintains consistent 14.4V rail voltage even under severe heat soak. The precision-machined housing fits directly to the factory bracketry, restoring electrical stability across the entire rev range of the \u003cstrong\u003e2.2L Ecotec\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x 250 Amp High Output Alternator\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;\"\u003e2008-2010 Pontiac G5\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;\"\u003e2.2L Ecotec (L61\/LAP) \/ GM Delta\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;\"\u003e148-155 hp \/ 150-152 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;\"\u003e20758751, 22762984, 11164N, 11164R, 11265, 11265n, FG12S010, GMT319, GMX001, GMX384, GMX386, 420532, 2650532, 15828450, 11164\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\u003e2008 Pontiac G5 Base \/ SE (2.2L L4)\u003c\/li\u003e\n  \u003cli\u003e2009 Pontiac G5 Base (2.2L L4)\u003c\/li\u003e\n  \u003cli\u003e2010 Pontiac G5 Base (2.2L L4)\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 GM Delta G5?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2008-2010 Pontiac G5 equipped with the \u003cstrong\u003e2.2L Ecotec\u003c\/strong\u003e engine.
