Frequently Asked Questions
What clamps do I need to install this hose?
Hose clamps are not included. You'll need 2x clamps sized for 2.25" diameter hose—stainless steel t-bolt or worm-gear clamps work best for underhood heat and vibration.
Can I use this for both coolant and boost lines?
Yes. Silicone handles coolant, heater, and intercooler applications. For boost pressure lines, confirm your system's PSI rating matches the hose's burst pressure—this hose is rated for high-temperature environments but verify boost compatibility with your specific setup.
Do I need to prep or clean the hose before connecting it?
Rinse the interior with clean coolant or distilled water to remove any manufacturing residue. Let dry before installation. No surface prep needed—the hose is ready to use once clamps are tight.
