What This Hose Helps Address

• Coolant seepage at the hose section
• Restricted coolant flow in the bypass circuit
• Service replacement for aging radiator coolant hose routing
• Cooling-system maintenance on Toyota Camry and Lexus RX applications

Installation Notes

Verify hose routing, diameter, and length against the original part before installation. For the 2004-2006 Toyota Sienna listing, the notes specify cut-to-fit, so measure carefully and trim only as required for the application. Confirm the cooling system is cool and drained to the proper service level before removing the old hose.
