Does this tank bolt directly into my Avalon without modifications?

Yes. This tank mounts at factory locations using existing points—no drilling, welding, or bracket fabrication. Test-fit to confirm alignment before final tightening.

Will I need to transfer the cap and internal components from my old tank?

Mounting method and internal component compatibility are not specified—inspect both tanks before installation to determine what transfers and what stays with the new assembly.

Can I install this myself with basic hand tools?

Replacement tanks typically require only a socket set and hose clamps to disconnect and reconnect coolant lines. Drain coolant completely before removal to avoid spills.
