Do I need to resurface or clean the mounting surfaces before installing this gasket?

Yes. Wipe both mounting surfaces with a clean cloth to remove dirt and old gasket material. A light pass with fine sandpaper ensures better sealing, but heavy resurfacing isn't required for aluminum gaskets on flat mounting faces.

What bolts or fasteners do I need?

Fasteners aren't included. You'll need two bolts that match your application's thread size and length — check your original component or service manual for the correct spec. Standard stainless or zinc-plated hardware works here.

Can I reuse this gasket if I remove it?

One-time use is the safe call. Once compressed and seated, aluminum gaskets don't seal as reliably if reinstalled. Order a fresh one if you pull the component apart again.
