Concurrently, the OEM composite thermostat housing degrades under prolonged heat cycling, resulting in micro-cracks, stuck-open thermostat valves, and erratic coolant flow that causes localized hot spots across the cylinder heads.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive cooling service kit features a heavy-duty, belt-driven cast aluminum mechanical water pump matched with precision-machined internal impellers to optimize fluid dynamics and prevent cavitation. Paired with a pre-assembled mechanical spring-loaded thermostat inside an OE-spec thermal housing, this setup restores critical coolant loop pressurization. High-grade elastomeric gaskets and O-rings provide an airtight seal against the timing cover and block, resisting degradation from modern ethylene-glycol mixtures.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Mechanical Water Pump Assembly (belt-driven, pulley not included)\u003c\/li\u003e\n  \u003cli\u003e1 Mechanical Engine Coolant Thermostat with Housing\u003c\/li\u003e\n  \u003cli\u003e1 Water Pump Mounting Gasket\u003c\/li\u003e\n  \u003cli\u003eThermostat Housing Mounting Gaskets and O-rings\u003c\/li\u003e\n  \u003cli\u003eMounting Hardware (as pictured)\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;\"\u003e2006-2014 Lexus GS\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;\"\u003e3GR-FSE (3.0L), 2GR-FSE (3.5L) \/ S190, L10\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;\"\u003e245–306 hp \/ 230–277 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;\"\u003e1610039435, 1610039436, 1603131020, PA1170, 1430879, 14411589\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\u003e2006 Lexus GS300 3.0L Gas Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e2007-2011 Lexus GS350 3.5L Gas Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e2013-2014 Lexus GS350 3.5L Gas Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e2007-2011 Lexus GS450h 3.5L Full Hybrid Gas\u003c\/li\u003e\n  \u003cli\u003e2013-2014 Lexus GS450h 3.5L Full Hybrid Gas\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 S190 and L10 GS?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2006-2014 Lexus GS equipped with the \u003cstrong\u003e3GR-FSE\u003c\/strong\u003e and \u003cstrong\u003e2GR-FSE\u003c\/strong\u003e V6 engines.
