Good Radiator
OSC Heat Transfer Products® - Downflow Engine Coolant Radiator with Transmission Oil Cooler
Have had it over a year and it's working great. Tip: if you are installing in a Titan, use your original radiator cap instead of the standard style pressure regulating cap supplied with this radiator. The original bleeds air from cooling system into coolant tank. A standard style cap will trap air in the radiator.
