Detailed Description

OSC part 2752 is engineered as an OE-style replacement radiator for the Mitsubishi Montero, combining aluminum core construction with plastic tanks for a direct-fit layout. The radiator includes a plated transmission oil cooler and is built to match original cooler design requirements where equipped, helping maintain proper fluid temperatures in daily driving and demanding conditions. The core, headers, and tank assembly are fitted and torqued to factory specifications, and the unit is tested multiple times during production to verify cooler and assembly integrity. This radiator is a practical choice for Montero owners looking for a direct replacement that preserves factory-style fitment and cooling performance.

This part cross-references Koyorad A2752 for the same application.

Common Problems This Radiator Helps Address

• Overheating caused by a restricted or aging radiator core
• Transmission fluid temperature rise from a worn integrated cooler
• Coolant leaks from cracked tanks or weakened seals
• Reduced cooling efficiency in high-mileage Mitsubishi Montero vehicles
• Fitment issues from non-OE-style replacement radiators

Installation Notes and Tips

Verify inlet and outlet sizes, header dimensions, and cooler line spacing before installation. Transfer any required vehicle-specific components from the original radiator if needed, and inspect hoses, clamps, and coolant condition at the same time. After installation, refill and bleed the cooling system according to factory service procedures and check for leaks at the radiator and cooler connections.

Quality Assurance

OSC radiators are produced with engineering updates aimed at improving cooling durability and service life. Each unit is pressure tested during manufacturing, including cooler testing before tank installation and final assembly testing after completion. The design also incorporates enhancements such as increased fin density and thicker core construction to address heat load in higher-mileage vehicles.
