Detailed Description

This radiator is built to match original equipment form and function for Acura MDX and Honda Pilot cooling system service. One Stop Solutions uses premium-grade materials, cadmium-plated tubes, and a die-cut gasket to help maintain sealing integrity. The design also incorporates cooling-system enhancements such as added fin density and a thicker core to address heat load in higher-mileage vehicles. Part number 2740 is a practical choice when replacing a worn or leaking radiator on 2003-2006 Acura MDX or 2005 Honda Pilot models.

This part cross-references APDI 8012740 and Spectra Premium CU2740 for the same application.

Common Problems This Radiator Can Address

• Coolant leaks from a cracked or aging radiator tank
• Overheating caused by restricted or inefficient heat transfer
• Transmission fluid temperature concerns in radiator-equipped cooling systems
• Corrosion-related failure in the core or cooler passages
• Poor fit or sealing after a previous replacement

Installation Notes and Tips

Verify inlet and outlet hose sizes, cooler line routing, and mounting points before installation. Confirm that the vehicle uses the correct downflow configuration and transmission cooler layout for part number 2740. Flush the cooling system, inspect hoses and clamps, and refill with the correct coolant mixture after installation.

Quality Assurance

OSC tests the transmission and engine oil coolers before tank installation, checks the radiator core before assembly, and tests the completed unit again after assembly. Each radiator is individually pressure tested to help confirm sealing and cooling-system integrity.
