Product Details
Dayco Curved Radiator Hose 72411 is engineered as a formed coolant hose for the upper radiator connection on 2005-2010 Scion tC models. The EPDM rubber construction is suited for cooling-system use, while the curved shape helps maintain the intended hose path in the engine bay. With matching 1 5/16-inch inside diameters at both ends, this hose is specified for a direct-fit replacement where the original hose follows the same routing and connection size. Dayco 72411 is a practical choice for Scion tC upper radiator hose replacement and related cooling-system service.
Common Replacement Reasons
- Cracked or hardened radiator hose rubber
- Coolant seepage at the hose connection
- Loss of hose flexibility from age and heat cycling
- Incorrect fitment after prior cooling-system repair
- Need for a formed upper radiator hose on a Scion tC
Installation Notes and Tips
Verify the hose routing, end diameters, and upper-position application before installation. Inspect the radiator neck and engine-side connection for corrosion, residue, or sharp edges that can affect sealing. Replace worn clamps as needed and confirm the hose sits naturally without twisting once installed. This part fits 2005-2010 Scion tC, upper.
Quality Assurance
Dayco manufactures this hose to meet SAE J20R4 Class D-1 and SAE J1684 Type EC requirements for radiator coolant hose applications. The protective sleeve adds an extra layer of abrasion protection in the specified routing area.
