Frequently Asked Questions
Does this hose come with clamps?
Clamps are not included. You'll need hose clamps sized for 3.75" diameter — stainless steel is the move for longevity.
Can I use this with my factory thermostat housing and water pump?
As long as your factory connections are 3.75" ID, this hose will bolt straight in. Measure your existing hose diameter before ordering to confirm fitment.
How do I prep the hose before installation?
No prep needed. Clean both your connection points and slide the hose on hand-tight first, then secure with your clamps. Tighten gradually — don't over-cinch and crush the silicone.
