Vacuum Check Valve

WARNING: This page is about a different car, the 1995 Ford Pickup, 1995 Ford Econoline, 1995 Ford Club Wagon, and 1995 Ford Bronco. However, it is still accessible from the selected car via links, so may be relevant.

Apply 16 in. Hg vacuum to check side of valve and trap. If vacuum remains greater than 15 in. Hg for 10 seconds, valve is okay. If vacuum drops faster, replace valve.
