For some in the racing world, KOYO is the number one ticket. All the radiators we offer are great for the 1993-1998 Supras.

☼ Nocolok Brazing - Tubes, Fins, Headers, and Brackets are brazed in a state-of-the-art Nocolok Furnace, bonding all components into an indestructible radiator.

☼ OE Specification Mounting - Fan mounts are situated to OE specifications allowing for both stock and performance fans to be used.

☼ Hand-crafted Heliarc Soldering - Each radiator is TIG-welded by hand with Heliarc soldering. Heliarc soldering is the highest in industry standard for welding aluminum connections.

☼ Tube and Fin Alignment - Construction under strict quality control and solid boxing result in pristine tube and fin alignment, fresh from the factory.

☼ Koyo Mirror Finish - All Aluminum surfaces are buffed before boxing to a confident mirror finish.

☼ N-Flo Construction (Double-Pass) - Strategically placed partitions make for a "N" or "U" shaped flow through the radiator. This allows for improved cooling efficiency compared to normal all-aluminum racing models. (N-Flo models are denoted by a "N" at the end of the product number)

Additional Information:

☼ Koyorad All-Aluminum racing radiators are made for manual transmission applications only. Automatic transmission models will require an external transmission cooler.

☼ Due to the oversize construction of All-Aluminum Racing Radiators, certain applications may fit tighter when used in different modification settings. Koyorad Racing Radiators are designed to meet OEM-Specific settings.

☼ Koyorad Racing Radiators are all-core radiators.

☼ ~20%-30% more efficient cooling over stock radiators.

NOTE: For automatic transmissions, please select the oil cooler and fan kit below, as it will be needed for the installation.

For the 1993-1998 Supra owners many people want to know if there is a specific radiator for the automatic transmission cars. The answer is yes, there is. The Toyota original radiator on automatic transmission equipped Supra Twin Turbo's came with an internally built-in oil cooler for the transmission fluid. With the exception of a special-order PWR radiator, all aftermarket performance radiators are designed without an oil cooler, so you will need to buy an aftermarket oil cooler with an electric fan, which we can add as an option.

"Okay, that is good information Mark, now I want to know if the manual transmission radiators (all aftermarket) will fit without any problems in my automatic car." Absolutely, yes they will fit.

Buy one of our great radiators, then get yourself one of our oil cooler with fan kits and you are 100% good to go. Hope that helps.

What about radiator fluid for aluminum radiators? Here is what you want to run (if possible). Toyota Red anti-freeze or Toyota Pink (pre-mixed 50/50), DISTILLED WATER (do not use water from the tap) and a single bottle of Redline Water Wetter (or your preferred water wetting ICE additive). Put one bottle of the additive in first, then again 2 liters of Toyota Red, then top off with DISTILLED WATER. Purge as required to remove air bubbles. If you are running Toyota Pink (pre-mixed 50/50) then add the bottle of water wetter first and top-off with the Toyota Pink.

If you do not have access to Toyota Red fluid, then buy a quality fluid that is Toyota rated and you will be fine. People can be real anal about radiator fluid, but follow the basic principals above, and you will be fine.

Please note that you will need the Koyo or SupraStore radiator cap for this radiator.
