Detailed Product Description

The CSF 3689 radiator features a 7/8 inch thick aluminum core measuring 29 7/16 inches wide and 19 3/4 inches long, optimized for the Mazda CX-9 cooling system. The plastic tanks are engineered to OEM specifications, ensuring compatibility and reliable sealing. Both the inlet and outlet have a diameter of 1 3/8 inches and are located on the left side, supporting straightforward hose connections. The down flow design promotes efficient coolant circulation through the single core row, while the integrated 14 3/4 inch high-efficiency concentric oil cooler enhances overall thermal management. This radiator does not include a cap, so the existing cap should be reused or replaced separately if needed.

Common Applications and Problem Solving

• Replacement for leaking or cracked radiator tanks
• Restoring cooling efficiency in Mazda CX-9 vehicles with overheating issues
• Upgrading from damaged or corroded radiator cores
• Addressing coolant flow restrictions due to clogged or bent radiator fins
• Maintaining engine temperature stability during extended driving or towing

Installation Notes and Tips

When installing the CSF 3689 radiator, ensure the inlet and outlet hoses match the 1 3/8 inch diameter and left-side positioning. Verify that the radiator core dimensions fit within the engine bay without interference. Since the radiator does not include a cap, retain the original or source a compatible cap separately. Properly bleed the cooling system after installation to avoid air pockets and ensure optimal coolant flow.
