Over decades of thermal cycles and chassis twist on unpaved terrain, factory crimp gaskets harden, split, and leak under operating pressure. Furthermore, restricted factory tube volumes quickly succumb to thermal saturation during low-speed rock crawling or hill climbs, leading to vapor lock and dangerous coolant spikes in both the AMC four-cylinder and GM-sourced V6 platforms.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct replacement is constructed from aircraft-grade aluminum featuring 100% TIG-welded end tanks and a furnace-brazed 4-row core. By eliminating failure-prone plastic tanks and mechanical crimp seals, burst tolerance is substantially increased. The dense fin-and-tube arrangement expands coolant contact surface area, enhancing thermal dissipation rates even in low-velocity airflow scenarios. It drops directly into the OEM factory mounts without chassis modification.\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;\"\u003e1986-1990 Jeep Comanche\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;\"\u003eAMC 150 (2.5L) \/ GM LR2 (2.8L) \/ MJ Chassis\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;\"\u003e115-117 hp \/ 135-150 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\u003e1986 Jeep Comanche (2.5L I4 AMC 150, 2.8L V6 GM LR2)\u003c\/li\u003e\n  \u003cli\u003e1987 Jeep Comanche (2.5L I4 AMC 150)\u003c\/li\u003e\n  \u003cli\u003e1988 Jeep Comanche (2.5L I4 AMC 150)\u003c\/li\u003e\n  \u003cli\u003e1989 Jeep Comanche (2.5L I4 AMC 150)\u003c\/li\u003e\n  \u003cli\u003e1990 Jeep Comanche (2.5L I4 AMC 150)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jeep Trail Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for the demands of off-camber articulation, utility hauling, and prolonged trail idle.
