Installation Notes and Tips

Ensure compatibility with your Toyota Highlander model year before installation. The CSF 3505 radiator is designed for direct replacement with OEM-style plastic tanks and aluminum core. Verify inlet and outlet hose diameters match your vehicle’s hoses (1 3/8 inches). Since the radiator does not include a cap, use a compatible CSF cap number 4514 or your vehicle’s original cap. Properly bleed the cooling system after installation to avoid air pockets and ensure optimal performance.
