Would you like a built-in transmission cooler?
New bolt-in aluminum crossflow radiators! The crossflow design has two 1-inch rows which offers better coolant flow and more cooling capacity than 4-core radiators. These radiators are available with a built-in automatic transmission cooler (select from the pull-down menu). 

These are fully welded (no epoxy, glue or gaskets).

These come set up for 258 straight-6 equipped Jeeps.

Note: transmission cooler lines relocated to driver side (longer flexible transmission cooling hose required)
Note: we recommend the use of Teflon applied to the transmission cooler fittings, but DO NOT use Teflon Tape, as it can bind and ruin the aluminum threads of the cooler. You should use liquid Teflon Tape instead.

Note: Stock Fan Shroud will not work with this radiator without modifications.
