Aluminum Crossflow Radiator LS / Vortec V8 Engine Conversion 1972-1991

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 are designed for FSJ's with a Vortec 5.3 / 6.0 / 4.8 / 6.2 Engine Swap

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.

Steam Port is included with plug to block it if you're not using one.

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

Note: Black paint is a 2-part epoxy coating that holds up really well on aluminum. It does not help or hurt the cooling in any way
