ECMRAD Aluminum Radiator is produced and designed to provide maximum cooling efficiency to prevent engine cooling failure. It is made of full aluminum light-weight, and high-heat transferring aluminum features a tube and fin design that, dramatically increases surface area that enables the heat to dissipate more efficiently. It has an increased durability over the factory plastic end tank radiator, and much inmprovwed engine cooling. Most importantly, it has a much higher capacity for coolant than stock ones, which means that your cooling system will be more efficient and will be more resistant to temperature surges in racing applications.This Aluminum Radiator Compatible for: for 1972-1983 Jeep CJ5 3.8L / 4.2L / 5.0L for 1973-1975 Jeep CJ6 All Models for 1976-1986 Jeep CJ7 3.8L / 4.2L / 5.0L Radiator Size Details: Core Size: 23 3/4 W x 15 3/4 H x 2'' T Overall Dimension: 24 1/4 x 20 3/4 Surface finish: Aircraft 5057 grade aluminum tank & core Radiator Cap: CNC machined filler neck and cap Petcock Drain: OEM style brass petcock drain Aircraft 5057 grade aluminum and with raw aluminum finish Package Included: 1 X 3-Row Aluminum Radiator w/ Radiator Cap in a Carton Box Upgrade Radiator Replacement for 72-86 JEEP CJ5 CJ6 CJ7 3.8L 4.2L 4.3L 5.0L AT/MT Core Size: 23 3/4 W x 15 3/4 H x 2'' T, Overall Size:24 1/4 x 20 3/4 Full aluminum construction with durable, TIG-welded end tanks Increased durability over the factory plastic end tank radiator TIG-welded aluminum radiator includes high-pressure rad cap and magnetic drain plug ASIN B09QPSX6NL Brand Name ECMRAD Part Number ECM-R-2078 Manufacturer CoolingMaster Direct Mounting Type Chassis Mount Cooler Heatsink Material Aluminum Item Dimensions L x W x H 23.75 L x 20.75 W x 20.75 H Global Trade Identification Number 04624339738548
