Plastic PA66-GF30 tanks pair with longer header tabs for leak-resistant tank seating, and the included transmission oil cooler means no hunting for a separate unit. At 24.45 inches tall and 27.64 inches wide with a 2.2-inch core depth, this radiator meets OE dimensions for a straight swap with no modification required.
