Restore quiet operation and eliminate unwanted vibrations with this updated heater hose. If you are hearing a vibration, moan or buzz-type noise coming from the passenger side or under the hood, this may be your issue. This noise is often described as coming from the passenger-side front of the engine compartment or the cowl area, and is typically most noticeable when engine RPM is raised between 2300 to 2600 RPM.

This replacement hose corrects the issue by allowing proper orientation and relieving stress at the connection point ensuring a quieter cab and more enjoyable Duramax.

New upgraded hose.

My truck was leaking from the quick connect under the firewall. I had to replace the quick connect and I upgraded the hose that you guys sold me. I thought the hose would get rid of the vibration under the firewall when I accelerate, but it did not eliminate that noise. Maybe that noise is something else or another hose. However, I am happy with the new quick connect and the hose that you sold me.
