Over operational cycles, the thermal expansion and contraction from the \u003cstrong\u003eM272\u003c\/strong\u003e naturally aspirated V6 degrade the plastic tank structure. Heat-cycled PA66 plastic embrittles, resulting in hairline fissures at the radiator inlet and outlet necks. Simultaneously, the crimped elastomer perimeter gaskets harden, introducing pressurized fluid leaks and catastrophic coolant loss that risks cylinder head warpage under sustained load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a drop-in replacement, this heavy-duty cooling assembly features a high-density, furnace-brazed 3-row aluminum tube-and-fin core that increases fluid capacity and convective heat transfer surface area. The failure-prone plastic tanks are replaced by laser-cut, TIG-welded aluminum end tanks designed to endure high operating pressures without deforming. Precision-machined inlet and outlet ports ensure leak-free coupling to factory quick-connect hoses, actively counteracting thermal saturation and heat soak in tight roadster engine bays.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x 3-row all-aluminum direct-fit performance radiator\u003c\/li\u003e\n  \u003cli\u003eProtective transport caps on coolant 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;\"\u003e2005-2008 Mercedes Benz SLK-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;\"\u003e\n\u003cstrong\u003eM272\u003c\/strong\u003e (3.0L, 3.5L V6) \/ \u003cstrong\u003eR171\u003c\/strong\u003e\n\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;\"\u003e228-268 hp \/ 221-258 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;\"\u003e\n\u003cstrong\u003eCU2337\u003c\/strong\u003e, \u003cstrong\u003eMB3010103\u003c\/strong\u003e, \u003cstrong\u003eMB3010154\u003c\/strong\u003e\n\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\u003e2006-2008 Mercedes-Benz SLK280 3.0L V6 (R171)\u003c\/li\u003e\n  \u003cli\u003e2005-2008 Mercedes-Benz SLK350 3.5L V6 (R171)\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 R171 SLK-Class?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2005-2008 Mercedes Benz SLK-Class equipped with the \u003cstrong\u003eM272\u003c\/strong\u003e 3.0L and 3.5L V6 engines; it does not fit the supercharged 1.8L four-cylinder SLK200 or the V8-powered SLK55 AMG.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the cooling system after installation?\u003c\/h4\u003e\n\u003cp\u003eYes, full vacuum bleeding is required during coolant refill to eliminate air pockets from the reverse-flow M272 cylinder head water jackets.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mercedes Benz Precision Standard\u003c\/h3\u003e\n\u003cp\u003eMaintain European sports car reliability with precision-welded cooling components manufactured to tight tolerances, ensuring zero warning lights, zero fitment modifications, and consistent operating temperatures under demanding thermal conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67553130840312,"sku":"DS-E0YUJ3H83","price":164.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/radiator-for-mercedes-benz-slk-class-slk280-slk350-2005-2008-3-0l-3-5l-1.jpg?v=1790826848","url":"https:\/\/performancechiptuning.com\/es\/products\/radiator-for-mercedes-benz-slk-class-slk280-slk350-2005-2008-3-0l-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
