Continuous heating and cooling cycles trigger differential thermal expansion between the plastic and aluminum, resulting in brittle tank seams, stress cracking, and coolant pressure loss. Furthermore, the undersized OEM core struggles with heat soak when towing or idling in high ambient temperatures, jeopardizing head gaskets on both 4.7L and 5.7L powerplants.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed entirely from aircraft-grade aluminum, this replacement eliminates crimped perimeter gaskets through 100% precision TIG-welded structural tanks. The high-capacity 3-row brazed tube-and-fin core dramatically increases fluid contact area and airflow heat dissipation over stock dimensions. Designed as a bolt-in upgrade, it retains OEM mounting geometry and integrated transmission cooling provisions to resist severe vibration and duty-cycle strain.\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;\"\u003e2007-2009 Chrysler Aspen\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;\"\u003e4.7L PowerTech \/ 5.7L HEMI V8 \/ HG Platform\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;\"\u003e235–376 hp \/ 300–401 lb-ft (Approx)\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;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2007–2009 Chrysler Aspen Limited 4.7L V8\u003c\/li\u003e\n  \u003cli\u003e2007–2009 Chrysler Aspen Limited 5.7L HEMI V8\u003c\/li\u003e\n  \u003cli\u003e2008–2009 Chrysler Aspen Signature Series 4.7L V8\u003c\/li\u003e\n  \u003cli\u003e2008–2009 Chrysler Aspen Signature Series 5.7L HEMI V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Chrysler Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle sustained gross combined vehicle weight ratings (GCWR), this unit provides substantial thermal reserve margins, preventing overheating and internal transmission cooler fatigue across steep grades and demanding towing conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50496527827192,"sku":"DS-EP9ST3YPB","price":308.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/aluminum-radiator-for-chrysler-aspen-2007-2009-4-7l-5-7l-1.jpg?v=1789245570","url":"https:\/\/performancechiptuning.com\/fr\/products\/aluminum-radiator-for-chrysler-aspen-2007-2009-4-7l-5-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
