Customer Question

I'm trying to restore a 1989 Dodge D150 with a 5.2 V8 and an automatic transmission. There's a vacuum problem and the mechanic thinks the Air Switch Relief Valve solenoid is bad but he can't find the part so I'm trying to help him out. The part is located on the left side of the the engine and alongside 2 other similar looking solenoids. Any idea where I could find the part.
JA: How many miles are on the car? Is it the original transmission?
Customer: 230,000 miles on the engine and 180000 on the transmission.
JA: Are you fixing your D150 yourself? What have you tried so far?
Customer: No I'm not fixing it myself, it's in a shop and they're having a hard time finding the part so I'm trying to help.
JA: Anything else you want the mechanic to know before I connect you?
Customer: I don't think so.

No that's not the part I need although everything on the internet directs me to the part when I try to search for the air switch relief valve solenoid. The part I need has an electrical connector on it and is located on the left rear side of the engine where as the part you're showing is located on the front right side of the engine. There are 2 other solenoids right next to the I need one is called a purge solenoid and the other is called the EGR solenoid. All 3 solenods look the same and I would buy all 3 if they come together.

I've attached photos of diagram on the truck hood and the actual part I need which is the middle of the 3 solenoid.

Hi Robert. The mechanic working on my truck says there are 3 ports on the solenoid and there are lines attached to all of them.
Expert:  Robert R replied 5 days ago.

I was researching this part on the NAPA web site. There are several similar solenoids available through NAPA. My recommendation is to take your existing part over to NAPA and have them get you something that will work for you. I also seen some of the solenoids have different connectors which you can purchase aftermarket jumper wire connectors that will fit the new part. You can have your mechanic solder in the pigtail connector inline to be able to connect to the NAPA supplied Solenoid..

Keep me posted and let me know if you have any additional questions...

Thank you,

Robert
