1-Row Radiator

The CSF 2946 is a 1-row radiator constructed with an aluminum core and plastic tanks, featuring a core size of 17-3/4 x 27-1/4 x 1-1/4 inches and an inlet tank size of 27-3/4 x 1 inch. This radiator is engineered with 1.375-inch inlet and outlet ports and includes a 5/16-inch hose barb connection for the transmission cooler line. Transmission cooler adapter fittings are included with this unit. This radiator is noted as being for supercharged applications and automatic transmissions. It can also fit manual transmissions, and the transmission coolant line does not require plugging. The CSF 2946 has been listed for fitment on the 2001-2004 Nissan Frontier 3.3L and 2002-2004 Nissan Xterra. Fitment for the 2014 Cadillac Escalade is also indicated, with notes on it being a multi-fit unit that may include dual oil coolers and additional oil cooler fittings. When considering installation, some users have reported that modifications might be necessary for certain vehicles. For example, on some BMW E46 models, the OEM radiator mounts and expansion tank bracket may not directly fit due to differences in radiator height, requiring bracket adjustments. While this CSF radiator is designed as an OE-style replacement, it is always recommended to verify specific fitment details for your vehicle's year, make, model, and trim.
