Installation Notes and Tips

Verify the radiator thread size, connector style, and harness routing before installation. The TS-454 uses a rectangular female plug-in connector with male blade terminals and no mounting bracket, so the existing radiator port and connector condition should be checked carefully. Confirm the vehicle application against the listed Acura CL, TL, or MDX fitment before replacement.
