Over time, the repeated heat cycling degrades the factory glass-filled nylon end tanks, making them brittle. The joint between the aluminum core header plate and plastic tanks frequently weakens, resulting in hairline fissures, weeping coolant, and sudden pressure loss. Additionally, road debris and fin oxidation diminish core surface heat rejection, triggering elevated coolant temps and potential engine derating.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to resolve stock fatigue, this replacement radiator combines a high-efficiency aluminum tube-and-fin core with reinforced composite end tanks. The internal core features multi-louvered cooling fins optimized for maximum ambient airflow penetration and accelerated heat exchange. Precision-crimped gaskets and reinforced inlet\/outlet necks resist expansion fatigue from elevated system pressures. Built to exact OE dimensional tolerances, it integrates directly with stock transmission oil cooler circuits and chassis mounts, completely restoring cooling performance for OEM part numbers \u003cstrong\u003eA0995008800\u003c\/strong\u003e and \u003cstrong\u003eA0995007100\u003c\/strong\u003e without line alteration.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; margin-bottom: 20px;\"\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;\"\u003e2018-2019 Mercedes Benz S-Class\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;\"\u003eM276 (3.0L) \/ M176 (4.0L) \/ W222\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;\"\u003e362-463 hp \/ 369-516 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;\"\u003eA0995008800, A0995007100, 0995003303, A0995005000, A0995006703\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2018-2019 Mercedes Benz S-Class S450 3.0L V6 (M276)\u003c\/li\u003e\n  \u003cli\u003e2018 Mercedes Benz S-Class S560 4.0L V8 (M176)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the W222 S-Class?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2018-2019 Mercedes Benz S-Class equipped with the \u003cstrong\u003eM276\u003c\/strong\u003e 3.0L or \u003cstrong\u003eM176\u003c\/strong\u003e 4.0L engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre modifications required for the transmission cooler lines?\u003c\/strong\u003e\u003cbr\u003e No, this unit features OE-pattern internal cooler fittings designed for factory quick-connect transmission lines with zero modifications.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mercedes Benz Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEuropean luxury flagships demand strict thermal tolerance management to protect advanced electronics and twin-turbo induction systems.
