When paired with the substantial thermal load of the \u003cstrong\u003eL410\u003c\/strong\u003e 6.75-liter V8, degraded factory cores quickly experience thermal saturation. At low vehicle speeds or long idle periods, the degraded heat rejection capacity causes coolant spikes, putting head gaskets and auxiliary systems under intense pressure.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a drop-in replacement, this radiator features a full aircraft-grade aluminum construction with a high-capacity 40 mm 2-row core. Precision TIG-welded aluminum end tanks eliminate the failure-prone soldered seams of the OEM component. The crossflow cooling tubes and high-density louvered fin design optimize air-to-coolant heat transfer across the entire 19.29 x 25.59-inch core surface. Designed to match factory plumbing, it integrates standard 1.50-inch inlet and outlet connections alongside internal transmission oil cooling circuits for automatic models without cutting or bracket relocation.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x All-Aluminum 2-Row Radiator\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: solid font-size: min-width:\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;\"\u003e1986-1988 Rolls Royce Silver Spirit,Silver Spur\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\u003eL410\u003c\/strong\u003e 6.75L V8 \/ \u003cstrong\u003eSZ\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;\"\u003e225 hp \/ 340 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\u003cstrong\u003e323Y1-US\u003c\/strong\u003e\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\u003e1986-1988 Rolls Royce Silver Spirit 6.75L V8 (Automatic Transmission)\u003c\/li\u003e\n  \u003cli\u003e1986-1988 Rolls Royce Silver Spur 6.75L V8, including Limousine (Automatic Transmission)\u003c\/li\u003e\n  \u003cli\u003e1987-1992 Bentley Mulsanne \u0026amp; Mulsanne S 6.75L V8 (Automatic Transmission)\u003c\/li\u003e\n  \u003cli\u003e1988-1998 Bentley Eight \u0026amp; Turbo R 6.75L V8 (Automatic Transmission)\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 SZ Silver Spirit,Silver Spur?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1986-1988 Rolls Royce Silver Spirit and Silver Spur equipped with the \u003cstrong\u003eL410\u003c\/strong\u003e engine and automatic transmission.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the system during installation?\u003c\/h4\u003e\n\u003cp\u003eYes, technicians must perform a complete cooling circuit flush and thoroughly bleed all air pockets to prevent hot-spot formation within the aluminum engine block.\u003c\/p\u003e\n\n\u003ch3\u003eThe Rolls Royce Caliber\u003c\/h3\u003e\n\u003cp\u003eEuropean luxury drivetrains depend on strict thermal regulation; this all-aluminum core ensures factory cooling equilibrium is maintained under severe heat loads without triggering coolant warnings.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67610965672184,"sku":"DS-E3TCHD08Y","price":242.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/radiator-for-rolls-royce-silver-spirit-silver-spur-1986-1988-6-8l-1.jpg?v=1791567012","url":"https:\/\/performancechiptuning.com\/de\/products\/radiator-for-rolls-royce-silver-spirit-silver-spur-1986-1988-6-8l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
