Detailed Description

One Stop Solutions part number 78 is a replacement radiator designed around original equipment dimensions and cooling layout. It uses premium aluminum tubes and fins, cadmium-plated tubes, and factory-style fitted components to help maintain cooling efficiency and durability in higher-mileage Jeep Cherokee, Comanche, and Wagoneer vehicles. The radiator measures 31 inches in core height, 10 9/16 inches in core width, and 1-1/4 inches in core thickness, with 1 1/2-inch inlet and 1 1/4-inch outlet connections.

This radiator is built with a crossflow configuration, plastic tanks, and an integrated engine oil cooler. It is engineered for direct replacement service where OE-style fit and function are required, and it is tested during production to verify the core and cooler assemblies before final assembly and again after completion.

What It Helps Address

• Overheating caused by a worn or restricted radiator core
• Coolant leaks from aging tanks, seams, or gasket surfaces
• Reduced cooling efficiency in high-mileage Jeep Cherokee, Comanche, and Wagoneer models
• Heat buildup from a failing or inefficient engine oil cooler circuit
• Fitment issues from non-OE-style replacement radiators
