Factory water pumps on the \u003cstrong\u003eLM4\u003c\/strong\u003e and \u003cstrong\u003eLS2\u003c\/strong\u003e engines routinely suffer from cartridge seal breakdown and mechanical bearing degradation past 60,000 miles. Thermal cycling causes the internal mechanical shaft seals to weep coolant past the discharge orifice, contaminating adjacent accessories. Concurrently, factory belt tensioners lose internal spring dampening, leading to harmonic vibration, belt flutter, and localized belt glazing that compromises alternator and power steering output during aggressive acceleration.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive service assembly utilizes a precision die-cast aluminum water pump housing fitted with reinforced internal unitized seals and a high-flow, cavitation-resistant impeller. The integrated thermostat housing maintains uniform operating temperatures, resisting coolant cavitation across all RPM bands. The included high-tensile cast-steel spring tensioner provides continuous dynamic torque to damp accessory harmonics, while matched, synthetic EPDM micro-V serpentine and A\/C belts prevent parasitic slip and resist heat cracking under extreme bay temperatures.\u003c\/p\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;\"\u003e2003-2006 Chevrolet SSR\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 LM4 \/ 6.0L LS2 \/ GMT368\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;\"\u003e300-400 hp \/ 331-400 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;\"\u003e12580162, 12609719, 12560380, 12562458, 12703898, 19195104\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\u003e2003-2004 Chevrolet SSR 5.3L Vortec LM4 V8\u003c\/li\u003e\n  \u003cli\u003e2005-2006 Chevrolet SSR 6.0L LS2 V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the GMT368 SSR?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2003-2006 Chevrolet SSR equipped with either the \u003cstrong\u003eLM4\u003c\/strong\u003e or \u003cstrong\u003eLS2\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eAre replacement gaskets and hardware included with this assembly?\u003c\/h4\u003e\n\u003cp\u003eYes, the kit includes required premium water pump mounting gaskets and direct-fit hardware for a complete, leak-free installation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Muscle Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle the violent power delivery of high-displacement small-block V8s, this cooling assembly ensures your retro muscle roadster maintains stable operating temperatures and zero accessory slip whether idling in traffic or operating under wide-open throttle.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67544640487672,"sku":"DS-ELC1JJ9XF","price":193.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-water-pump-kit-for-chevrolet-ssr-2003-2006-5-3l-6-0l-1.jpg?v=1790708422","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-water-pump-kit-for-chevrolet-ssr-2003-2006-5-3l-6-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
