more than a grand, yep, radiator for a class 8 truck runs from $1.000.00 to about $1,800.00 depending on the engine and truck mfg. But keep in mind we are talking about a 12 gallon rad, and an engine that holds 10 gallons of oil. But they make 1,500 ft. lbs. of torque, and most of my trucks run 3,500 miles a week or more, Kinda of extreme heavy duty, huh.
