Will this tank work with my stock cooling system?

Yes. Mounting points and hose connections are designed to match your factory setup without modification.

Do I need to drain the old tank before swapping it in?

Yes. Drain your coolant first, unbolt the old tank, and swap in the new one at the same mounting locations. Refill with fresh coolant once installed.

Can I install this myself or does it need a shop?

This is a straightforward bolt-swap. Basic hand tools and a drain pan are all you need. No special equipment required.
