Having enough cooling for your engine is an issue we engine swappers encounter in garages and on trails across the nation. We went to the experts at Advance Adapters for our radiator. With over 40 years of experience helping wheelers swap parts into their 4x4, these guys have seen it all. In fact, our request for a radiator to put a Chevy V-8 in a Jeep was about as mundane as can be, and the company’s crossflow aluminum radiator fit perfect in our CJ grille. Mounting holes are not drilled, so you can adjust the height in the grille as desired. Note the blue caps on the right side of the radiator; these are fittings for an internal transmission cooler, where we will plumb in our 4L80E transmission.
