Frequently Asked Questions
Will this silicone hose work for coolant and boost lines, or just one?
This is a general-purpose silicone hose rated for coolant loops, vacuum circuits, and turbo boost lines. Temperature and pressure handling depend on clamp tightness and total line design β verify your system's peak PSI and coolant temp before committing.
What clamps do I need?
Hose clamps are not included. You'll need worm-gear or band-style clamps sized for 3.5-inch diameter β pick stainless steel to avoid rust transfer to the silicone.
Can I install this myself with basic hand tools?
Yes β slip it over barbed fittings and tighten clamps evenly on both ends. If you're replacing an existing line, drain the system first and let it cool so you don't burn yourself pulling old hose.
