The heat generated by the AJ-V8 platform causes the stock polymer end tanks to embrittle, resulting in micro-fractures at the tank-to-core seams and inlet neck stress points. Additionally, restricted internal tube volume in factory cores accelerates heat soak during aggressive driving, compromising transmission fluid cooling and triggering thermal derating.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis drop-in performance unit is constructed from 100% TIG-welded, 2 mm aircraft aluminum sheet with zero epoxy or plastic failure points. Featuring a high-efficiency 4-row crossflow configuration with 3\/8-inch tube spacing and 14–16 fins per inch (FPI), it maximizes surface area for rapid heat dissipation. The vacuum-brazed core increases cooling capacity over OEM specifications, while the integrated internal transmission cooler maintains stable line temperatures to prevent fluid breakdown and transmission slippage.\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;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2009-2011 Jaguar XF\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eAJ-V8 (4.2L \/ 5.0L) \/ X250\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e300–385 hp \/ 310–380 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eCore Dimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e20 in x 22.5 in (Overall: 29 in x 21 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eInlet \/ Outlet\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1-5\/8 in \/ 1-5\/8 in\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eDPI 13148 \/ 3W4Z8005AA, 5W4Z8005AA, 6W4Z8005AA, XW4Z8005BA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2009–2010 Jaguar XF 4.2L V8 Automatic\u003c\/li\u003e\n  \u003cli\u003e2010–2011 Jaguar XF 5.0L V8 Automatic\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jaguar Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact European OE dimensional tolerances, this cooling assembly installs cleanly into factory mounts without modifications, sensor re-routing, or check engine lights, delivering reliable thermal headroom for high-output British powertrains.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50416634265848,"sku":"DS-EV220FKWW","price":329.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-jaguar-xf-2009-2011-4-2l-5-0l-automatic-1.jpg?v=1788323209","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-radiator-for-jaguar-xf-2009-2011-4-2l-5-0l-automatic","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
