Will this hose fit my existing clamps?

The 3.50" outer diameter works with standard hose clamps, but you'll need to verify your current clamp size before installation. Measure the ID of your existing clamps — most bolt-style and worm-drive clamps adjust across a range, so compatibility is usually straightforward.

Do I need to prep or condition the hose before installing it?

No prep needed. Wipe the hose down with a clean, dry cloth before connecting it, then secure both ends tightly with appropriately sized clamps. Tighten clamps evenly and check them again after your first heat cycle.

Can I use this for both intake and discharge lines?

This hose is designed for high-temperature coolant circulation in both directions. The 3-ply construction handles both the suction side (intake) and pressure side (discharge) of your cooling system without issue.
