4x4 Vacuum Solenoid Purge Valve 4WD Locking Hub Vacuum Solenoid 7L1Z-9H465-B Compatible With Ford Expedition Ford F-150 F-250 F-350 F-450 F-550 Super Duty Lincoln Navigator

Perfect fit for my 2012 F150 5.0. Getting the hoses off the old one was the hardest part (without ruining the lines) and even that only took a couple minutes. Everything slid right into place during the install.

Fits like OEM part and performs just as well

Easy to install

good product

If you have 4wd problems with your F150 this solenoid should be the first thing you check. Unlike other 4wd systems, the Ford has "normally vacuum" mode to put the front end free-wheeling (other vehicles use vacuum to pull up the actuators to engage 4wd ... 2012 Ford F150s are opposite of that). This solenoid has two vacuum line connections. To test, start your truck ... pull off both vacuum lines (noting which one goes where). One of the vacuum lines should have vacuum on it while your vehicle is running. If it doesn't, you have a vacuum problem. Look upstream of the vacuum line for your failure. However, if you do have vacuum on one of the lines, plug that one back into the solenoid. Test the other port of the solenoid by putting your finger across it. If the truck is in 2wd then there should be vacuum on that second port. If you switch the dash switch to 4wd, the vacuum should go away on the second port. If your current solenoid isn't behaving as described above, this solenoid should fix your problem. If it doesn't, then you probably have an electrical problem. If your solenoid tests good but you don't have 4wd, then the next thing to look at is vacuum actuators located on the hubs. That fix is far more involved.BTW ... this part install requires no tools whatsoever and literally takes under a minute. Pull the two lines off ... unsnap the solenoid ... install the new solenoid ... reinstall the two vacuum lines ... boom ... you're done.

Fixed the IWE issue right away. Low speed grinding went away instantly after installing. Replaced the check valve and hose as well, solenoid was the issue.

On the day I recieved it I disconnected the electrical connector from the existing solenoid and plugged it into the new 4x4 Vacuum Solenoid Purge Valve to test it and heard no sound and felt no suction with the vehicle running. Defective upon arrival. I had meant to return it but misplaced it and then forgot about it. Anyways I was cleaning out my truck today and found it under the seat still in the box. I tested it again and still defective. It's too late to return it but I do not recommend buying this product!
