Dayco 72064 Radiator Coolant Hose - Upper

Dayco Curved Radiator Hose for Mirage

Dayco 72064 is a curved radiator coolant hose built for upper cooling-system routing on select Mitsubishi Mirage models. It uses EPDM construction and a dual I.D. design to match the varying connection sizes found in this application.

Compatible with 1997-2002 Mitsubishi Mirage, upper, this Dayco curved radiator hose supports a direct-fit cooling system repair for the Mirage platform. The molded shape helps follow the factory hose path, while the black EPDM material is specified for coolant-hose service.

Product Details

Dayco’s Curved Radiator Hose line focuses on molded coolant hoses that follow the vehicle’s original routing and connection geometry. For this application, the 72064 hose is shaped for the upper radiator position on 1997-2002 Mitsubishi Mirage models and uses a dual inside diameter profile to accommodate the different end sizes required by the cooling circuit. The EPDM material is a common choice for radiator hose service because it is formulated for coolant exposure and under-hood temperatures.

This part cross-references Mitsubishi (e.g., MR204562) for the same application.

What It Helps Address

• Cracked or hardened upper radiator hose material
• Coolant seepage at the hose connection points
• Incorrect hose fitment from universal replacements
• Routing issues caused by a hose that does not match the factory curve
• Cooling-system service on a Mitsubishi Mirage upper hose location

Installation Notes and Tips

Verify the end diameters and upper hose routing before installation. Inspect the radiator neck, engine-side connection, and clamps for wear or corrosion, and replace damaged sealing surfaces as needed. Confirm the hose follows the original path without twisting so the molded curve seats correctly on the 1997-2002 Mitsubishi Mirage cooling system.

Quality Assurance

Dayco manufactures this hose to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications for radiator coolant hose service. The 72064 part number is also listed under common aftermarket references for the same Mirage upper hose application.
