Will this mount using factory attachment points?

Yes. This tank mounts at factory rocker and engine bay mounting points with no drilling or bracket fabrication required. Install goes straight in.

Do I need to drain the cooling system to swap this in?

A full system drain is not mandatory. You can cap or clamp the hose connections to minimize coolant loss, swap the tank, and refill. Still a good idea to have fresh coolant ready in case of small spillage.

Can I reuse the cap and hose connections from my old tank?

Cap reuse depends on its condition—if the seal is still firm and there's no visible cracking, it's fine. Hose connections are usually good to reuse unless they're brittle or cracked. Inspect them before reassembly.
