Over decades of thermal cycling, vibration, and pressure fluctuation, the original tank seals degrade, leading to hairline fractures, seam leaks, and catastrophic coolant loss. Furthermore, internal galvanic corrosion and mineral scale buildup within the narrow stock core tubes drastically restrict coolant flow velocity. This causes heat soak and elevated operating temperatures in high-compression diesel and inline-six powerplants, especially during sustained highway hauling or idle conditions in traffic.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a robust drop-in replacement, this heavy-duty unit features an all-aluminum tube-and-fin core furnace-brazed to precision hand-TIG-welded aluminum end tanks. Eliminating brittle plastic components and failure-prone rubber gaskets entirely, the all-aluminum construction withstands higher internal operating pressures and extreme thermal shock. The high-density louvered fin matrix maximizes surface area contact, accelerating ambient airflow exchange and dropping coolant inlet temperatures significantly faster than stock. Designed to match factory mounting locations, it provides a seamless mechanical install while replacing \u003cstrong\u003eOEM 123 500 37 03\u003c\/strong\u003e.\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;\"\u003e1976-1985 Mercedes Benz E-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;\"\u003eOM617, OM616, M110, M115 \/ W123\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;\"\u003e62-182 hp \/ 97-177 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;\"\u003e123 500 37 03\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1976-1985 Mercedes Benz E-Class 300D 3.0L\u003c\/li\u003e\n  \u003cli\u003e1976-1983 Mercedes Benz E-Class 240D 2.4L\u003c\/li\u003e\n  \u003cli\u003e1977-1981 Mercedes Benz E-Class 280E 2.8L\u003c\/li\u003e\n  \u003cli\u003e1976-1978 Mercedes Benz E-Class 230 2.3L\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the W123 E-Class?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1976-1985 Mercedes Benz E-Class equipped with the OM617, OM616, M110, or M115 engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this radiator accommodate automatic transmission cooling lines?\u003c\/strong\u003e\u003cbr\u003e Yes, it features integrated internal transmission cooler connections configured for factory line thread pitches.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mercedes Benz Precision Standard\u003c\/h3\u003e\n\u003cp\u003ePreserve classic European engineering integrity with cooling components built to tight manufacturing tolerances.
