Detailed Description
Built for Ram cooling system service, the CSF 3738 radiator follows an OE-style layout with a 27 1/2 in. core length and 21 11/16 in. core width. The 1 1/2 in. left inlet and 1 3/4 in. right outlet match the listed application geometry, while the cross-flow design supports efficient coolant routing through the aluminum core. CSF manufactures radiators to high-performance standards and uses lab testing to validate cooling performance before release. This radiator is a direct replacement choice for Ram 1500, Ram 2500, Ram 3500, and Ram 1500 Classic applications listed below.
This part cross-references Bosch 13493 for the same application.
Common Cooling System Issues Addressed
- Cracked or leaking radiator tanks
- Corrosion or damage in the radiator core
- Restricted coolant flow from an aging radiator
- Overheating caused by reduced heat dissipation
- Replacement needs after impact or wear-related failure
Installation Notes and Fitment
Fits 2019 Ram 1500 Classic, N/A.
Fits 2014-2018 Ram 1500, N/A.
Fits 2014-2018 Ram 2500, N/A.
Fits 2014-2018 Ram 3500, N/A.
Verify inlet and outlet orientation, core dimensions, and hose connection sizes before installation. The radiator is listed without a cap, and the OE-style plastic tank and aluminum core construction should be matched to the vehicle’s original cooling system layout.
