Detailed Description

OSC radiator Part Number 2259 is designed as a direct replacement for the factory radiator used in the Nissan Quest and Mercury Villager from 1999 through 2002. It measures 25 3/8 inches in core height, 18 1/8 inches in core width, and 1 inch in core thickness, with 1 3/8-inch inlet and outlet diameters. The unit is built with premium-grade components and engineered to match original cooling system layout while addressing common wear points found in older vehicles.

For buyers searching for a 1999-2002 Nissan Quest radiator or 1999-2002 Mercury Villager radiator, this unit provides OE-style cooling performance with a transmission cooler integrated into the tank. This part cross-references APDI 8012259 for the same application.

Common Problems This Radiator Can Address

• Coolant leaks from an aging radiator core or tank seam
• Reduced cooling efficiency from clogged or weakened internal passages
• Transmission fluid temperature concerns tied to a failing cooler circuit
• Cracked or brittle plastic tank issues on older factory radiators
• Fitment problems caused by non-OE-style replacement parts

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet sizes, and cooler connections before installation. This radiator is built for drop-in fitment on listed applications, but the cooling system should be inspected for hose condition, clamp wear, and contamination before the new unit is installed. Flush the system as needed and confirm proper coolant fill and bleed procedure after installation.

Quality Assurance

OSC tests the radiator core before assembly and tests the completed unit again after assembly, with additional testing of the transmission and engine oil cooler circuits prior to installation into the tank. The design uses premium materials and factory-style engineering enhancements to improve durability and cooling performance in high-mileage vehicles.
