Over decades of heat cycles, OEM solder seams crack, leading to recurring coolant loss. Furthermore, factory mechanical fan clutches slip with age and fail to pull adequate CFM across the core at low vehicle speeds, causing rapid coolant temperature spikes when idling or working under heavy bed loads.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis cooling upgrade features an all-aluminum tube-and-fin core paired with 100% \u003cstrong\u003eTIG-welded\u003c\/strong\u003e end tanks, eliminating failure-prone epoxy bonds and fragile crimped seams entirely. Structural aircraft-grade aluminum optimizes heat dissipation efficiency while cutting overall front-axle dry weight. Matched with an integrated aluminum fan shroud and dedicated electric cooling fan assembly, airflow is evenly channeled across the entire surface area of the core rather than dissipating within the engine bay. The internal transmission oil cooler provisions maintain factory plumbing routing for reliable fluid stabilization.\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;\"\u003e1975-1986 Chevrolet C\/K Trucks\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;\"\u003eInline-6 (4.1L\/4.8L), SBC Gen-I V8 (5.0L\/5.7L) \/ \u003cstrong\u003eSquarebody (C\/K 3rd Gen)\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;\"\u003e105-175 hp \/ 185-275 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\n\u003cstrong\u003eCC161\u003c\/strong\u003e, \u003cstrong\u003eMC161\u003c\/strong\u003e, \u003cstrong\u003eDPI161\u003c\/strong\u003e, \u003cstrong\u003e161\u003c\/strong\u003e, \u003cstrong\u003eCU161\u003c\/strong\u003e, \u003cstrong\u003eRAD161\u003c\/strong\u003e, \u003cstrong\u003eSBR161\u003c\/strong\u003e, \u003cstrong\u003e3023837\u003c\/strong\u003e, \u003cstrong\u003e3025227\u003c\/strong\u003e, \u003cstrong\u003e52453863\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\u003e1975-1986 Chevrolet C10 (4.1L 250ci, 4.8L 292ci, 5.0L 305ci, 5.7L 350ci)\u003c\/li\u003e\n  \u003cli\u003e1975-1986 Chevrolet C20 (4.1L 250ci, 4.8L 292ci, 5.0L 305ci, 5.7L 350ci)\u003c\/li\u003e\n  \u003cli\u003e1975-1986 Chevrolet C30 (4.8L 292ci, 5.7L 350ci)\u003c\/li\u003e\n  \u003cli\u003e1975-1986 Chevrolet K10 (4.1L 250ci, 5.0L 305ci, 5.7L 350ci)\u003c\/li\u003e\n  \u003cli\u003e1975-1986 Chevrolet K20 (4.1L 250ci, 4.8L 292ci, 5.0L 305ci, 5.7L 350ci)\u003c\/li\u003e\n  \u003cli\u003e1975-1986 Chevrolet K30 (4.8L 292ci, 5.7L 350ci)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the Squarebody C\/K Trucks?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1975-1986 Chevrolet C\/K Trucks equipped with the \u003cstrong\u003eSmall Block Chevy\u003c\/strong\u003e or factory inline-six engines.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this unit retain the internal automatic transmission fluid cooler?\u003c\/strong\u003e\u003cbr\u003e Yes, it features integrated brass transmission cooler ports compatible with factory transmission lines.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Durability Standard\u003c\/h3\u003e\n\u003cp\u003eSquarebody work trucks are built to pull heavy equipment and run for decades in punishing environments.
