GM Genuine Parts 15-50568 (15733271) Vacuum Check Valve

Exactly what I need. Perfect replacement part. Works as intended. Excellent price. Easy install.

It’s in a GM parts bag, but it’s the same little check valve used across different brands. The price for this version is the best I could find. Along with some new vacuum hose, I used this check valve to fix the vent/defroster duct problem on a 95 F150. Hopefully they’ll still be making these check valves when this one quits in a couple of decades, lol.

The product is designed just right. I used it on my E450 RV A/C repair and worked very well. Very satisfied

It works great at a nice price.

For years I've dealt with my truck only having airflow at the defrost blowing on the windshield. No matter what setting I put the air on, it only came out at the windshield. Now this truck is 29 years old, lots of things no longer work, like the A/C or the light at the vanity mirror (which I cut the wire on because it would not turn off anymore and had drained and destroyed a nearly new battery and who needs a light on the vanity mirror?) and I usually drive with the windows down anyway, but it bothered me that I knew this had to be an easy fix. I checked out some youtube videos and narrowed it down to this part or something way more involved that required a smoke machine and tearing out the dashboard which I am not doing because I'm a 5'2" woman and the one time I removed the door panel to replace the side mirror I learned my brain is stronger than my arms and I lacked the strength to remove everything much less get it all back together, I'd live with the defrost setting because on a nearly 30 year old truck I'm not spending a lot of money on it and it drives, I'm happy for that much. It's not a daily driver. I had to have my husband remove the old part, because the vacuum tubes on it were really on there good and again my brawn is not as powerful as my brain, I knew what needed to be done, I just needed someone else's muscle to do it. So it got switched out and nothing changed...but this is a vacuum issue, it's not an immediate fix, you have to give it time to get cleared out and being to vacuum the way it is supposed to. So maybe in the 3rd trip out with the truck, I tried moving the vent flow around and behold it now comes out at the dash and not windshield unless I actually have it on defrost. So this part fixed my problem and for the price is was well worth it.

The valve fits and works fine, but the quality is lacking. The vacuum hose ports have sharp edges and should have been cleaned up from the factory.

Have an Astro, Safari or S10? You probably need to replace a bunch of vacuum lines if you haven't already. This is one of the components in that system. Make sure you install in the correct orientation.

Worked as should

Perhaps I have some other issues

Le queda a camaro 1996 RS

I installed this to my 3005 GMC savana and as they claim acdelco being OEM for GMC’s, but it only lasted two months

Tengo solo un dia con el producto y fue realmente facil remplazar el deposito de vacio de mi AC en mi ford van e-150 2011. Esperemos dure un buen tiempo y de no ser asi el precio es justo para volver a reemplazar la valvula.

Funciono perfectamente, ahora ya todas las ventilaciones funcionan correctamente.
