Stock TT (Calsonic) radiator - works great, no leaks, however part of the top hose inlet slightly cracked off about 3/8 inch at the very tip of the inlet. The radiator hose holds perfectly fine. Apparently just about all of the stock TT radiators have this small portion of the plastic inlet break off at the same place as they age. See pics for detail. Comes with stock Nissan radiator cap. Selling only because I upgraded to a Koyo aluminum. Will be shipped in the Koyo box.
