I am working on replacing the vaccum check valve in the HVAC system right by the intake manifold. When I removed the old check valve I forgot the direction that it was setup. Can someone help me with which direction it should be. I currently have it flowing into the intake manifold. Is this correct?

 

Should be an arrow on the valve, indicating flow direction. You want that pointed toward the intake manifold.

 

Perfect thank you much! Time to take her for a drive and see if my AC Blowing out of the defrost when at 1/3+ throttle is fixed.

 

I don't believe there is anything on the originals(mine didn't have anything). If you need replacements you can get them from NAPA.
Yes!

 

Thanks Moparite I got one from Napa as my current check valve didnt work well but it didnt have any direction on it. So I blew thru it to see which direction it should flow.

Everything back in place and good to go. Thanks!
