The original crimped end tanks are notorious for fatigue cracking, petrifying gasket seals, and micro-fracturing along the upper hose neck under typical operating pressure. Compounding this, the narrow OEM core tube pitch clogs easily with mineral scaling and oxidation, drastically dropping coolant flow rates across the \u003cstrong\u003eM116.962\u003c\/strong\u003e \/ \u003cstrong\u003eM116.960\u003c\/strong\u003e V8 engine block.

Robotically TIG-welded structural aluminum end tanks eliminate failure-prone mechanical crimp seams, handling continuous pressure fluctuations with zero risk of delamination. Optimized internal multi-louvered fin density maximizes ambient airflow cross-exchange, counteracting heat soak during aggressive driving or low-speed stop-and-go conditions. Outfitted with precision-machined inlet and outlet ports matching factory routing, it integrates directly with your existing oil and transmission cooling circuits to ensure dependable thermal regulation across all operating bands.\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;\"\u003e1981-1985 Mercedes Benz SL-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;\"\u003e3.8L V8 (M116) \/ R107, C107\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;\"\u003e155 hp \/ 196 lb-ft (US-Spec 380SL)\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\u003e1075011701\u003c\/strong\u003e, \u003cstrong\u003e1075011401\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1981-1985 Mercedes Benz SL-Class 380SL 3.8L V8 (R107)\u003c\/li\u003e\n  \u003cli\u003e1981 Mercedes Benz SL-Class 380SLC 3.8L V8 (C107)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the R107 SL-Class?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1981-1985 Mercedes Benz SL-Class equipped with the M116 3.8L engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this radiator accommodate the internal automatic transmission cooler lines?\u003c\/strong\u003e\u003cbr\u003e Yes, it features integrated threaded fittings engineered to match OEM transmission line connections with no modification required.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mercedes Benz Precision Standard\u003c\/h3\u003e\n\u003cp\u003eClassic European engineering leaves no margin for sloppy clearances or unstable engine temperatures.
