Over repeated thermal expansion cycles, these composite tanks embrittle and crack along the header seams. Furthermore, packing a 5.3L V8 into the compact Colorado engine bay severely restricts airflow, leading to rapid heat soak, elevated automatic transmission temperatures, and eventual overheating during steep grades or towing.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered for maximum thermal dissipation, this performance downflow unit features 100% aircraft-grade aluminum construction with precision TIG-welded tanks that completely eradicate mechanical crimp-seal failures. The robust 3-row core (23.2\" W x 18.7\" H) significantly increases cooling surface area and fluid capacity over OEM standards. A built-in M14 x 1.5 internal transmission oil cooler maintains optimal automatic transmission fluid viscosity under severe operating conditions.\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;\"\u003e2009-2012 Chevrolet Colorado\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;\"\u003e5.3L LH8 \/ LH9 V8 \/ GMT355\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 hp \/ 320 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;\"\u003eDPI 2855 \/ 25964053\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVehicles:\u003c\/strong\u003e 2009-2012 Chevrolet Colorado (5.3L V8 Automatic Models Only)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e 25964053, 25964054, 25827383, 15828003, 15828004\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterchange Numbers:\u003c\/strong\u003e DPI 2855, CU2855, RAD2855, Q2855, CC2855, MC2855, HU3010101, HU3010102\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitment Note:\u003c\/strong\u003e Direct bolt-on.
