Detailed Description

One Stop Solutions 2986 is a replacement radiator designed for Mazda CX-9 cooling system service where the original vehicle uses a tow package configuration. The radiator uses premium-grade aluminum construction with cadmium-plated tubes inside and out to help resist premature failure, while the factory-style plastic tanks and die-cut gasket support a leak-resistant seal. The integrated concentric transmission cooler is built into the unit, and the radiator is assembled to factory specifications for fit and function.

This radiator is built for direct replacement use on the Mazda CX-9 and follows OE cooler design requirements where originally equipped. The 2986 application is focused on restoring proper coolant flow and transmission fluid cooling in vehicles that need a replacement radiator for the 2007-2015 Mazda CX-9 platform.

Common Problems This Radiator Can Address

  • Coolant leaks from a cracked or aging radiator tank
  • Overheating caused by restricted or damaged radiator flow
  • Transmission temperature issues related to a failing integrated cooler
  • Reduced cooling efficiency in high-mileage Mazda CX-9 vehicles
  • Fitment problems from a non-OE-style replacement radiator

Installation Notes and Tips

Verify the vehicle has the 27-inch core and tow package configuration before installation. Confirm inlet and outlet sizes, cooler line routing, and mounting points against the original radiator. This radiator is built for drop-in replacement use, and all necessary fittings or hardware are included in each unit. For best results, inspect hoses, clamps, and coolant condition during radiator replacement.

Quality Assurance

OSC Premium radiators are tested during production, including cooler testing before tank installation, core testing before assembly, and a final assembled-unit test. The design also incorporates engineering updates aimed at improving durability and cooling performance in higher-mileage vehicles.
