Ram changed the radiator hoses, water pump and thermostat housings for 2019, and 2013-2018 cooling parts do not carry over, so a radiator for an earlier truck is not a substitute.

The 3944 is made to meet the exact specifications and materials of the original equipment radiator. CSF engineers the design and wind-tunnel tests it in a lab for cooling performance validation, and the radiator is manufactured in ISO\/TSO certified factories.\u003c\/p\u003e\n\u003cp\u003eThe construction follows the factory layout: OEM-specified plastic tanks on a 2-row aluminum core in a cross-flow design, sealed with gaskets made from special grade EPDM rubber. Because CSF built it as a drop-in replacement that works with all original equipment, there is no cutting, bending or adapting. That matters on a 2019-and-newer truck, where the cooling parts are specific to this generation.\u003c\/p\u003e\n\u003ch2\u003eWhat you get\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOne CSF 3944 OE-style radiator: plastic tanks, 2-row aluminum core, cross-flow design\u003c\/li\u003e\n\u003cli\u003eBuilt with gaskets constructed from special grade EPDM rubber\u003c\/li\u003e\n\u003cli\u003eRadiator cap is not supplied\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMeets OE Specs\u003c\/li\u003e\n\u003cli\u003eOE-Style Replacement\u003c\/li\u003e\n\u003cli\u003eDirect-Fit Installation\u003c\/li\u003e\n\u003cli\u003eHigh-Quality Construction\u003c\/li\u003e\n\u003cli\u003eManufactured In ISO\/TSO Certified Factories\u003c\/li\u003e\n\u003cli\u003eGaskets Constructed From Special Grade \"EPDM\" Rubber\u003c\/li\u003e\n\u003cli\u003eOEM Specified Plastic Tank-Aluminum Core Construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBottom Hose Fitting (in): 1 15\/16 Right\u003c\/li\u003e\n\u003cli\u003eBox Height (in): 8 1\/4\u003c\/li\u003e\n\u003cli\u003eBox Length (in): 44 5\/8\u003c\/li\u003e\n\u003cli\u003eBox Weight (lbs): 21\u003c\/li\u003e\n\u003cli\u003eBox Width (in): 23 3\/4\u003c\/li\u003e\n\u003cli\u003eCore Length (in): 33 3\/8\u003c\/li\u003e\n\u003cli\u003eCore Material: Aluminum\u003c\/li\u003e\n\u003cli\u003eCore Thickness (in): 1 5\/8\u003c\/li\u003e\n\u003cli\u003eCore Width (in): 20 5\/16\u003c\/li\u003e\n\u003cli\u003eCross-flow\/ Down-flow: Cross Flow\u003c\/li\u003e\n\u003cli\u003eHazardous Material: No\u003c\/li\u003e\n\u003cli\u003eInlet Length (in): 20 7\/8\u003c\/li\u003e\n\u003cli\u003eInlet Width (in): 2 3\/16\u003c\/li\u003e\n\u003cli\u003eNo. Of Rows: 2\u003c\/li\u003e\n\u003cli\u003eOil Cooler (in): No\u003c\/li\u003e\n\u003cli\u003eOutlet Length (in): 20 7\/8\u003c\/li\u003e\n\u003cli\u003eOutlet Width (in): 2 3\/16\u003c\/li\u003e\n\u003cli\u003eRadiator Cap Supplied: No\u003c\/li\u003e\n\u003cli\u003eTank Material: Plastic\u003c\/li\u003e\n\u003cli\u003eTech Note: O.E.M. style Plastic tank \u0026amp; Aluminum core\u003c\/li\u003e\n\u003cli\u003eTop Hose Fitting (in): 1 15\/16 Left\u003c\/li\u003e\n\u003cli\u003eApplications: 2019-2023 Ram 3500 6.7L Diesel (Standard Output)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNote: Does not fit High-Output engines\u003c\/p\u003e\n\u003ch2\u003eInstallation notes\u003c\/h2\u003e\n\u003cp\u003eCSF designed the 3944 as a drop-in replacement compatible with all original equipment, including the OEM hoses and mounting points\/brackets.

Is it the radiator?\u003c\/h3\u003e\n\u003cp\u003eMaybe not. On the 6.7L Cummins, an internal EGR cooler leak can cause coolant loss with no drips, white sweet-smelling steam on a cold start and a P2457 code. Have the cooling system pressure tested and find the leak before you replace a radiator that is not visibly dented or leaking.\u003c\/p\u003e\n\u003cp class=\"sds-pd-cta\"\u003eQuestions on fitment?
