2004-2005 Chevrolet Trailblazer Air Inject Check Valve - Dorman 911-003
Dorman makes this air inject check valve for installation on 2004 and 2005 Chevrolet Trailblazers. The air inject check valve ensures that air only flows one way through the valve. It acts like a stop gate to prevent backflow. When an air injection check valve stops working, the air pump may become damaged from the air backflow. When the air inject check valve is replaced, the air pump should also be examined and replaced, if needed. For the best fit, install this Dorman air inject check valve on Chevrolet Trailblazers made in 2004 and 2005. It may not be compatible with other vehicles.
Price was great, was delivered fast, and fit perfect. Has solved the problem.
Dorman makes good stuff and this is priced much better than the chain auto parts stores !!
The part is an exact match to the OEM part i replaced. Worked fine.
Shipping took a whole week, so if you are in a hurry probably should not use the standard rate or look to your local parts dealer. However the part's price was 40% less than the local stores!
