EGR Vacuum Solenoid Help.

[89CopCoupe]

I needed an EGR vacuum solenoid for my '89 5.0, so I went to a few of my local wreckers and found 1 on a '90 2.3 car. Visually it looks identical to the unit supplied on the 5.0 cars.

My question is do they interchange and operate the same

Plus, does the cap on top of it have to be there in order for it to function properly

Any help is appreciated, Thanks in advance

Check Autozone.com & see if the part numbers are the same.

The cap covers the filter element, and needs to be in place.

The '89 5.0 and '91-'93 2.3 are the same Thanks for response
