Detailed Description

OSC part number 2842 is a replacement radiator for the 2006-2012 Mitsubishi Eclipse, designed to match OE form and function while addressing common cooling-system wear points. It uses a single-row core, plastic tanks, and a concentric transmission cooler to support factory-style cooling performance. The radiator is engineered with cadmium-plated tubes and fitted components assembled to factory specifications, helping maintain proper sealing and fitment in the Mitsubishi Eclipse radiator application.

For buyers searching for a 2006-2012 Mitsubishi Eclipse radiator with transmission cooler, this unit is built as a direct-fit replacement with the necessary fittings and hardware included in the assembly. Part number 2842 is also a practical reference when comparing OE-style replacement options for the Eclipse cooling system.

Common Problems This Radiator Can Address

• Coolant leaks from a cracked or aging radiator tank
• Reduced cooling efficiency from clogged or damaged core passages
• Transmission fluid temperature concerns related to a failing cooler circuit
• Fitment issues caused by warped or deteriorated OE-style radiator components
• Overheating symptoms tied to worn fins, tubes, or sealing surfaces

Installation Notes and Tips

Verify inlet and outlet sizing, cooler line routing, and overall core dimensions before installation. Inspect the mounting points, hoses, and transmission cooler connections for wear or contamination, and flush the cooling system if the previous radiator failed from internal debris or overheating. This radiator is a downflow design, so confirm the vehicle’s original configuration matches the replacement before installation.

Quality Assurance

OSC tests the radiator core before assembly and tests the completed unit again after assembly; the transmission and engine oil coolers are also checked prior to installation into the tank. The design uses engineering updates aimed at improving durability and cooling performance in higher-mileage vehicles, including enhanced fin density and a thicker core where applicable.
