Over repeated thermal cycles, cyclic expansion and contraction weaken the vulcanized rubber gaskets sealing these tanks. This leads to hairline fissures in the plastic inlet and outlet necks, severe stress fractures, and sudden pressure loss. Furthermore, the single-row OEM core restricts fluid transit volume, resulting in progressive heat soak and elevated operating temperatures when the M112, M271, or AMG powerplants are driven aggressively.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to resolve structural fatigue, this direct replacement features a high-density, brazed 3-row aluminum core combined with 100% \u003cstrong\u003eTIG-welded\u003c\/strong\u003e aluminum end tanks. Eliminating composite materials and crimped seals completely removes the primary failure point of the stock system. The enlarged core profile optimizes fluid capacity while louvered aluminum cooling fins maximize surface heat dissipation across incoming ambient airflow. Built to mate directly with factory chassis brackets, this assembly provides uncompromising burst pressure resistance and consistent thermal efficiency for daily and high-load use.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x All-aluminum 3-row performance radiator\u003c\/li\u003e\n  \u003cli\u003eProtective shipping caps on fluid ports\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;\"\u003e2001-2009 Mercedes Benz C-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;\"\u003eM271, M111, M272, M112, M113 \/ W203, CL203\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;\"\u003e168-362 hp \/ 177-376 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;\"\u003eCU2337, MB3010103, MB3010154\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\u003e2001-2005 Mercedes Benz C240 (2.6L V6)\u003c\/li\u003e\n  \u003cli\u003e2001-2005 Mercedes Benz C320 (3.2L V6)\u003c\/li\u003e\n  \u003cli\u003e2002-2004 Mercedes Benz C32 AMG (3.2L Supercharged V6)\u003c\/li\u003e\n  \u003cli\u003e2002-2005 Mercedes Benz C230 (1.8L \/ 2.3L Supercharged I4)\u003c\/li\u003e\n  \u003cli\u003e2005-2006 Mercedes Benz C55 AMG (5.5L V8)\u003c\/li\u003e\n  \u003cli\u003e2006-2007 Mercedes Benz C230 (2.5L V6)\u003c\/li\u003e\n  \u003cli\u003e2006-2007 Mercedes Benz C280 (3.0L V6)\u003c\/li\u003e\n  \u003cli\u003e2006-2007 Mercedes Benz C350 (3.5L V6)\u003c\/li\u003e\n  \u003cli\u003e2001-2009 Mercedes Benz C-Class SportCoupe \/ CL203 (1.8L, 2.3L, 2.5L)\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 W203 C-Class?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for 2001-2009 Mercedes Benz C-Class models equipped with 1.8L, 2.3L, 2.5L, 2.6L, 3.0L, 3.2L, 3.5L, and 5.5L engines conforming to the \u003cstrong\u003eCU2337\u003c\/strong\u003e core configuration.
