Product Details

Dayco 73036 is a curved radiator hose for the lower coolant path on the Mazda 2. The EPDM material is commonly used in cooling-system hoses because it is suited to coolant exposure and engine-bay temperatures, while the curved shape helps follow the factory hose route. If you are replacing a worn lower radiator hose on a 2011, 2012, 2013, or 2014 Mazda 2, this part number 73036 provides the specified fitment and dimensions for that application.

Common Replacement Reasons

Cracked or split lower radiator hose
Coolant seepage at the hose connection points
Softening, swelling, or heat-related hose wear
Restricted coolant flow from a deteriorated hose
Maintenance replacement during cooling-system service

Installation Notes

Verify the hose routing, end diameters, and lower-position fitment before installation on your Mazda 2. Inspect the mating necks, clamps, and surrounding cooling-system components for wear or corrosion, and confirm the hose seats fully at both ends. Dayco 73036 is listed for 2011-2014 Mazda 2 lower radiator hose applications only.

Quality Assurance

This hose is manufactured to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications for radiator coolant hose service. Dayco 73036 is a direct-fit cooling-system replacement for the confirmed Mazda 2 applications listed above.
