Over time, original factory composite tanks suffer from chemical degradation due to old coolant, micro-fracturing under high-pressure cycles, and neck warping that ruins the radiator cap seal. If you notice a persistent drop in coolant level without a visible puddle, intermittent low-coolant lights, or white crusty residue around the seams, it is time for a replacement before a major hose blow-out occurs.\u003cspan\u003e\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"yhAwj\" data-sfc-cp=\"\" jsaction=\"rcuQ6b:\u0026amp;ZUT3re_u|npT2md\" jscontroller=\"UTzWVc#U8DOt\" data-sfc-root=\"c\" jsuid=\"ZUT3re_u\" data-complete=\"true\" data-processed=\"true\" data-sfc-inited=\"2\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"ZLzG0d ncoeY E8xBUb\" role=\"heading\" aria-level=\"3\" data-animation-nesting=\"\" data-sfc-cp=\"\" jsaction=\"\" data-wiz-attrbind=\"aria-level=ZUT3re_v\/fLk2Md\" jscontroller=\"zg1ZQe#TswZNc\" data-sfc-root=\"c\" jsuid=\"ZUT3re_v\" data-complete=\"true\" data-processed=\"true\" data-sae=\"\"\u003eCross-Reference \u0026amp; Part Numbers\u003c\/div\u003e\n\u003cdiv class=\"n6owBd awi2gc\" data-sfc-cp=\"\" jsaction=\"\" jscontroller=\"TDBkbc#Ml18Xb\" data-sfc-root=\"c\" jsuid=\"ZUT3re_w\" data-hveid=\"CAAICBAA\" data-complete=\"true\" data-processed=\"true\"\u003eTo ensure perfect fitment, this military-grade surge tank replaces and interchanges with the following part numbers:\u003cspan\u003e\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cul class=\"XSq4R KI3fJ\" data-sfc-cp=\"\" jsaction=\"\" jscontroller=\"wiLEJc#NS0kde\" data-sfc-root=\"c\" jsuid=\"ZUT3re_12\" data-hveid=\"CAAICRAA\" data-complete=\"true\" data-processed=\"true\"\u003e\n\u003cli class=\"Z1qcYe\" data-sfc-cp=\"\" jsaction=\"\" jscontroller=\"oSLmPe#HokZ0d\" data-sfc-root=\"c\" jsuid=\"ZUT3re_13\" data-hveid=\"CAAICRAB\" data-complete=\"true\" data-sae=\"\"\u003e\u003cspan class=\"iNqyIf\" data-sfc-cp=\"\" jsaction=\"\" jscontroller=\"KdQfFc#d5Qebf\" data-sfc-root=\"c\" jsuid=\"ZUT3re_14\" data-complete=\"true\"\u003e\u003cstrong class=\"rQesXe MPyX\" data-sfc-cp=\"\" jsaction=\"\" jscontroller=\"tP2kf#s32ZS\" data-sfc-root=\"c\" jsuid=\"ZUT3re_15\" data-complete=\"true\"\u003eNational Stock Number (NSN):\u003c\/strong\u003e 2930-01-256-5350, 2930PL0703685\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"Z1qcYe\" data-sfc-cp=\"\" jsaction=\"\" jscontroller=\"oSLmPe#HokZ0d\" data-sfc-root=\"c\" jsuid=\"ZUT3re_16\" data-hveid=\"CAAICRAC\" data-complete=\"true\" data-sae=\"\"\u003e\u003cspan class=\"iNqyIf\" data-sfc-cp=\"\" jsaction=\"\" jscontroller=\"KdQfFc#d5Qebf\" data-sfc-root=\"c\" jsuid=\"ZUT3re_17\" data-complete=\"true\"\u003e\u003cstrong class=\"rQesXe MPyX\" data-sfc-cp=\"\" jsaction=\"\" jscontroller=\"tP2kf#s32ZS\" data-sfc-root=\"c\" jsuid=\"ZUT3re_18\" data-complete=\"true\"\u003eMilitary \/ AM General Part Numbers:\u003c\/strong\u003e 12340061, 12340062, 5596079\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"Z1qcYe\" data-sfc-cp=\"\" jsaction=\"\" jscontroller=\"oSLmPe#HokZ0d\" data-sfc-root=\"c\" jsuid=\"ZUT3re_19\" data-hveid=\"CAAICRAD\" data-complete=\"true\" data-sae=\"\"\u003e\n\u003cspan class=\"iNqyIf\" data-sfc-cp=\"\" jsaction=\"\" jscontroller=\"KdQfFc#d5Qebf\" data-sfc-root=\"c\" jsuid=\"ZUT3re_1a\" data-complete=\"true\"\u003e\u003cstrong class=\"rQesXe MPyX\" data-sfc-cp=\"\" jsaction=\"\" jscontroller=\"tP2kf#s32ZS\" data-sfc-root=\"c\" jsuid=\"ZUT3re_1b\" data-complete=\"true\"\u003eCivilian Hummer H1 Part Numbers:\u003c\/strong\u003e 5744154\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"yhAwj\" data-sfc-cp=\"\" jsaction=\"rcuQ6b:\u0026amp;ZUT3re_1h|npT2md\" jscontroller=\"UTzWVc#U8DOt\" data-sfc-root=\"c\" jsuid=\"ZUT3re_1h\" data-complete=\"true\" data-processed=\"true\" data-sfc-inited=\"2\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"ZLzG0d ncoeY E8xBUb\" role=\"heading\" aria-level=\"3\" data-animation-nesting=\"\" data-sfc-cp=\"\" jsaction=\"\" data-wiz-attrbind=\"aria-level=ZUT3re_1i\/fLk2Md\" jscontroller=\"zg1ZQe#TswZNc\" data-sfc-root=\"c\" jsuid=\"ZUT3re_1i\" data-complete=\"true\" data-processed=\"true\" data-sae=\"\"\u003eVehicle Compatibility \u0026amp; Model Numbers\u003c\/div\u003e\n\u003cdiv class=\"n6owBd awi2gc\" data-sfc-cp=\"\" jsaction=\"\" jscontroller=\"TDBkbc#Ml18Xb\" data-sfc-root=\"c\" jsuid=\"ZUT3re_1j\" data-hveid=\"CAAICxAA\" data-complete=\"true\" data-processed=\"true\"\u003eThis coolant surge tank is compatible with 6.2L and 6.5L naturally aspirated and turbo diesel variants across the entire military M-series fleet.
