What fasteners do I need to mount this hose?

Mounting method depends on your plumbing layout — you'll typically use hose clamps (worm-gear or band-style, sized for your hose diameters) at each end. Test-fit before committing to clamp size.

Can I use this for both coolant and boost lines?

Yes. Three-ply silicone handles both coolant circulation and positive boost pressure. Just make sure your clamps and fittings are rated for the working pressure of your application.

Does this hose need any prep before installation?

No prep required. Slide it on, clamp both ends, and torque clamps evenly. Clean the hose ID and fitting OD first if either is dusty or oily.
