Koyo N-Flow Aluminum Radiator for SR20DET (89-94 S13)

Koyo Aluminum Radiator for your Nissan 240sx w/ SR20DET. High quality aluminum, with polished tanks. We highly recommend doing this upgrade when swapping in the motor, or soon after. Stop cooling issues before they start.

Koyo's "R" Series aluminum radiators feature a 53mm (2 1/16 in) thick, all aluminum core brazed to polished aluminum end tanks for a show quality finish. Koyo uses state of the art Nocolok Brazing Furnace to bond all of the radiator brackets, headers, tubes, and fins, creating high quality "indestructible" radiator. All aluminum end tanks are hand crafted using the latest Heliarc Soldering technique for the most reliable connections, then polished to a mirror finish.

All Koyo Racing series radiators have "OE Specification" mounting location for stock mounting without major modifications. Koyo Hyper Radiator Caps are also available to increase your cooling system pressure to 1.3 bar for increased cooling capacity. Racing series radiators were made for manual transmission only, however with a separate automatic transmission cooler.

Double Pass / N-FLO Construction 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.
