A new TOMS OFFROAD exclusive item! Our 4-core Tri-Flo Triple Pass Aluminum Heavy Duty Radiator for 66-77 Ford Broncos. This radiator has 4 rows of cooling tubes and requires 4-core brackets & bushings. It features a triple pass system that creates a longer path for coolant to flow through the radiator. This system allows for the coolant to come in contact with much more surface area of the radiator resulting in exceptional efficiency. This heavy duty aluminum radiator features a built in automatic transmission cooler. This radiator can be used with automatic or manual transmission. You just won't use the built in cooler for manual transmission setups. This heavy duty aluminum radiator will cool the most stubborn of heating problems. This radiator is designed for standard flow early Bronco setup. Not designed for reverse flow pump setups.

Keep in mind when choosing a radiator, there are a few key factors to consider such as size of engine, stock, mild or high performance. What you do with the Bronco and how harsh the climate is you drive in. A bone stock Bronco can be fine with the standard copper core radiator whereas the pumped up or oversized motor in the extreme condition will require the largest aluminum cored radiator. Whatever your application, we have a radiator that will keep you cool. If you need help choosing a radiator, call our staff and we will gladly help you choose the radiator for your Bronco. And most important, don't forget the shroud.

NOTE: We highly recommend a new 1/2 inch fan spacer #6446A when installing any 4-core or Aluminum Radiator. It is recommended that you have at least 1 inch space between the fan and the radiator to avoid damage. If you have power steering box that mounts on the inside of the frame, all 4-core & Aluminum Radiators will require modification to fit. 

Automatic or Manual Transmission?: If you have a automatic transmission, we recommend purchasing the radiator cooler line adapter fittings to hook up your cooler lines to the radiator. They can be selected in the drop down menu above.

WOW, After 2 decades this radiator has finally dropped my temps down almost 20 degrees across the board. 95 to 100 degree weather on the interstate and off roading stayed at 190 or lower this last week. Much better than the old 4 cord brass radiator. Thanks Tom’s

Besides normal day-to-day driving, this amazing radiator has gotten us through two Rebelle Rally competitions to date. Each rally we drive over 1500 miles throughout the California and Nevada mountains and deserts, all the way down to the USA-Mexico border. We drive all day, on and off-road, covering all terrain and elevations, reaching extreme external temperatures, even frequenting Death Valley, all at the end of summer, and we have never once overheated. Our Bronco temps remain low the entire time, which is more than we can say for ourselves!
